Features of this kit:
• Compatible—staining compatible with mass spectrometry analysis
• Protocol—protein bands (0.3 ng of protein) can be visualized within an hour or for added speed a microwave procedure can be completed in ∼30 minutes
• Color-coded solutions—color-coded solutions for easy staining protocol

Mass spectrometry-compatible reagents
The SilverQuest Silver Staining Kit has been specifically designed to make protein detection compatible with mass spectrometry analysis. The SilverQuest reagent set contains a sensitizer that contains no glutaraldehyde or formaldehyde, so it leaves lysine and arginine side-chains unmodified. Additionally, the SilverQuest destaining solution effectively removes silver from protein bands in polyacrylamide gels. Peptides remain as efficient targets for in-gel trypsin digestion and gel extraction and yield better coverage during mass spectrometry analysis.
