NT-L028 Spectral Shift Optimized Protein Labeling Kit For His-Tag Size Medium
This kit provides convenient means for the site-specific, purification-free labeling of small amounts of His-tagged proteins with our SpS-optimized fluorescent dye. It can be used for the labeling of any protein or peptide carrying a polyhistidine-tag (His-tag). Labeling can be completed in a few minutes and no removal of excess dye is required. The SpS-optimized dye binds efficiently to His-tags which contain at least six histidines with a Kd in the single digit nanomolar range.
The kit contains material sufficient for 500 data points.
