Description

Thermo Scientific Krypton Fluorescent Protein Stain enables sensitive visualization with fluorescence imagers (520nm excitation; 580nm emission) of proteins separated in polyacrylamide gels or transferred to membranes.

Features of Krypton Fluorescent Protein Stain:

Intense fluorescent stain—excitation and emission maxima of 520nm and 580nm, respectively (compatible with 532nm excitation light sources and 580 to 600nm emission filters)
Instrument-compatible—effective with popular laser-based and filter-based fluorescence imagers
Broad dynamic range—linear quantitative range spans three to four orders of magnitude Sensitive—detect as little as 0.25ng protein with the standard protocol (approx. 2.5 hours); at least as sensitive as fluorescent stains from other suppliers
Fast—standard (2.5 hours) and rapid (30 minutes) protocols are significantly faster than procedures of other popular fluorescent stains
Versatile—compatible with proteomics workflows involving downstream mass spectrometry
Compact—supplied as a 10X solution to save storage space; just dilute with water before use

This fluorescent protein gel stain is for bright yellow-orange fluorescent detection of proteins separated by 1D or 2D polyacrylamide gel electrophoresis (SDS-PAGE). Krypton Stain uses a protein-binding dye with fluorescence properties (Ex/Em = 520/580nm) suitable for visualization with a variety of standard laser-based and filter-based fluorescence imagers and documentation systems. Proteins are detectable at concentrations greater than 0.25ng per band in a typical mini-gel lane (greater than 2ng for the rapid staining protocol). Krypton Stain provides high signal intensity, exhibits minimal protein-to-protein variation, has an excellent quantitative dynamic range and is compatible with subsequent destaining and analysis by mass spectrometry.

For best results, detect bands using visible laser-based imagers equipped with a 532nm laser light source. Although 580nm-filters are optimal for emission, 600nm-filters are also compatible. Stained gels can be imaged on any platform with the respective excitation and emission filters.
