Amersham unveils new stain for proteomics
which it claims will improve the detection of proteins in 1D and 2D
Amersham Biosciences has launched a new protein stain, called Deep Purple, which it claims will enable scientists to detect and quantify proteins in gels more accurately and in greater quantities than ever before.
Deep Purple Total Protein Stain is a fluorescent stain for the detection and visualisation of proteins in 1D and 2D gels. The product offers up to eight times more sensitivity in protein detection, making it the most sensitive in-gel fluorescent total protein stain commercially available, according to the company.
"Deep Purple gives proteomics customers the ability to detect more proteins with greater accuracy while eliminating the problem of uneven levels of background fluorescence, known as 'speckling,'" said Amersham in a statement.
The stain can be used in every step of protein analysis, from sample preparation to mass spectrometry, and is compatible with Amersham 's Typhoon imager as well as with other industry standard fluorescent scanners.
"Deep Purple offers outstanding accuracy, quality and value for money. It provides up to eight times more sensitivity than other commercially available fluorescent stains while offering clear uniform backgrounds at around 30 per cent less cost than other products on the market," said Richard Cumming, vice president proteomics product management at Amersham.
