“We purchased the Sapphire Biomolecular imager to replace an aging, first generation Licor Odyssey scanner. Six months in and the Sapphire has proven to be a workhorse in the lab. With easy to use software, high resolution and the ability to scan 4 channels (2 IR 2 fluorescent) simultaneously , the Sapphire has given us the capacity to probe for multiple proteins at once without crosstalk between channels, thus eliminating the need to run and probe multiple gels. Equipped with a separate CCD camera, the Sapphire is capable of imaging both chemiluminescence Western blots and phosphoimaging screens, providing us a choice of detection methods. Our primary application is Western blotting, however the versatility of the machine has allowed us to do 96 well ELISA studies as well.

Analysis of blots or plates is very straight forward using the AzureSpot software.

Azure customer service has been excellent. Email enquiries are answered promptly and the service staff have gone above and beyond to help rectify the few minor issues we’ve had.

If you are in the market for an IR scanner, I would highly recommend considering the Sapphire for your lab.”

“I have used other Western blot imaging systems but they were too slow and complicated. The Azure c600 makes it easy to see my data quickly.

I use Femto grade ECL for hard-to-detect targets like low abundance proteins or targets with weakly binding antibodies. This used to give me problems with X-ray films that were full of dark spots or sometimes even turning completely dark. That never happens any more. The Azure c600 gives me very clean and nice looking results.

The system is fast and easy to use. I load the membrane on the tray and choose my imaging method with the touch of a button. I specially like how it records multiple cumulative images, so I never need to re-expose the membrane.”

“Before purchasing the Azure c600 we imaged our blots on a Typhoon 9410 fluorescence scanner from GE Healthcare.

We evaluated both the Odyssey CLx from Li-Cor and the Azure Biosystems c600. The Li-Cor and the Azure systems yielded similar results with both having identical limits of IR-based detection. On the other hand, the Azure c600 was more flexible (chemi, visible and infrared capabilities), and therefore had more to offer.

Three features that I appreciate about the c600 are i) the user-friendly graphical interface, ii) the quick and adjustable acquisition times and iii) the custom acquisition mode which allows one to detect information from multiple chemistries and then present the resulting merged image!”

“We pursued digital imaging because we were looking for a way to save time by skipping the dark room and having to scan film. We considered two other imagers that are on the market. We chose the Azure c300 system for the best cost, great-looking images while using the demo, large work area to accommodate larger western blots, and most importantly, ease of use. One person in the lab was resistant to switching to digital imaging at first, but has since come around because of the convenience, ease of use, and images that are equal to or better than film. None of us have had to use the dark room in over a year.

Considering how much we initially liked the machine, I was a little nervous about going with a product and company that were so new to the market. The sales and technical support have always been great and we are very satisfied.”

“We purchased the Azure imaging system to replace our previous digital imager (a Fluorchem Q) when it broke beyond repair. We chose the Azure system for several reasons. First, the machine itself was simple to use and had a small footprint, which is very important for our cramped bench space. Second, we were able to demo the machine. You cannot appreciate how easy-to-use a piece of equipment is until you have it in your hands without the field rep there to guide you. Third, Azure will send field reps to service the instrument. We chose Azure over Protein Simple because Protein Simple would not do this. Quality customer service is important for us because our lab is small and we are all very busy and unable to spend hours troubleshooting.

The Azure instrument has been great. We are currently using it for chemiluminescence and UV imaging. It is easy to use for these applications and we have obtained high-quality images. The cumulative capture feature for chemiluminescence in particular is a very useful feature for my work.”

“We purchased the Sapphire imager to replace our obsolete typhoon scanner and could not be happier with the performance and ease of use. Equipped with multiple lasers, it is possible to probe for many proteins at high resolution and with great sensitivity. We primarily use the system for western blotting and fluorescent slide scanning and have had clear, publishable results. The software is easy to use and has many practical features. Customer service is amazing – they are always available, informative, and as scientists, they assist with troubleshooting experimental design and optimizing results. This product is highly recommended for anyone who routinely uses electrophoresis, cell-based, or slide-based analyses with fluorescent or chemiluminescent detection.”

“Freedom to capture data for studying proteins and nucleic acids.

Traditionally, western blot detection methods have used X-ray films to capture chemiluminescence. However, the increasing costs for film, reagents, and maintenance made many researchers to shift from darkrooms to more sensitive and technologically advanced digital imaging systems such as Cooled charge coupled devices (CCD) cameras capturing both chemiluminescence and fluorescence images. The two mentioned detection methods allow the ability to simultaneously detect proteins on the same blot minimizing the need for stripping and reprobing leading to an increase in detection efficiency (Mathews, Plaisance et al. 2009).

Here, I will review Azure Biosystems imaging system for chemiluminescent, fluorescent and infrared imaging, and briefly discuss their advantages and disadvantages.

The Azure Biosystems C600 image analyzer.

C600 system is the only imaging system available in the market currently with the following features (i) infrared laser excitation for quantitative imaging in the near IR, (ii) picogram detection of proteins using chemiluminescence, (iii) wide range of dye selection with Cy®5/Cy3/Cy2 excitation, and (iv) option of upgradation from the base units c200, c300, c400 and c500. This increases the options of selecting different chemistry for performing western blots by using the same imaging system. Due to the signal stability and low background, detection in the near-infrared fluorescent (NIR) for western blot detection is achievable using the infrared fluorescent dyes. The NIR western detection also offers multiplexing allowing the option to detect multiple proteins at the same time. Azure Biosystems’ c600 system is equipped with two IR detection channels and allows users to study multiple proteins with overlapping in a blot. The image generated can be spectrally separated as the secondary antibodies are imaged in two different channel.

We have compared the image obtained and the analysis results were comparable to other laser detection system e.g. LiCOR odyssey western blot imaging system.

Chemiluminescence continues to be a favorite and sensitive method of detection. Azure c600 provides quantitative analysis with accurate, fast detection with superior sensitivity, dynamic range, and linearity needed for quantitative blot analysis by chemiluminescent means made possible due to the use of the high resolution, F 0.95 fast lens technology. The superiority of the analyzer is evident from the availability to use any HRP substrate allowing users to maintain the same protocol and capture images with the same sensitivity as film without the risk of oversaturation due to the broader window of detection of several orders of magnitude of protein concentration. The c600 can also be equipped with powerful LEDS for Cy5/Cy3/Cy2 imaging or similar dyes thus allowing the users the option to expand multiplexing. The c600 is also able to image a wide range of dyes (excitation maxima from 302 nm to 785 nm), enabling WesternDots™, Stain-Free™ gels and different types of in-gel fluorescence.

The c600 system also is of immense to molecular biologists with the inclusion of UV, white, and blue lights for imaging Ethidium bromide, Coomassie, and non-mutagenic dyes like Gel red and Gel green.

Features of the machine

  • Two Channel Infrared (IR) Direct Detection – Laser diodes at 660nm and 785nm
  • Three Channel RGB Excitation – For Cy5/Cy3/Cy2 applications
  • Fast Chemiluminescent Detection
  • Capture of gel and blot images on a single instrument
  • 4.3 OD Dynamic Range
  • Camera captures images with spatial resolution down to 40 μm (microns) for chemiluminescence applications and 60 μm (microns) for gel and fluorescent applications
  • Analysis software- AzureSpot software is very friendly, easy to use and efficient to detect and subtract the immunoblot background

Azure c600 machine offers great value for the money as it combines the functionalities of laser NIR imager with chemiluminescent camera in one simple affordable machine.

The after sales service provided by Azure Biosciences is of highest professional standard, with arrangement of hands-on training beginning from installation to detailed explanation of functioning of the machine. The technical team took into consideration about minor technical information while explaining the functioning of the Azure spot software. We had faced problem once with regards to the software and it was promptly resolved by the Azure Biosciences team.

The technical team is also helping us to explain the analysis beyond western to analyze multiplexing on glass bead format as is available for the analysis of many cytokines and key molecules from many supplier as well as thick tissues pre-labelled with dye probe e.g. GFP protein.

“Before purchasing the Azure c600, we evaluated its performance against the Odyssey CLx from LI-COR. The LI-COR and the Azure systems had similar limits of IR-based detection, but the Azure c600 was more versatile (chemi, visible and infrared capabilities), and therefore had more to offer. The c600 has an easy to use graphical interface and offers both default and customizable acquisition modes. The fast acquisition time and the ability to simultaneously detect information from multiple chemistries are definitely what sets this instrument apart from scanning-based imagers. Additionally, the Azure service team is very responsive, making improvements to the software/hardware as per customer demand.”
