Biotinyl-Asp-Glu-Val-Asp-aldehyde (pseudo acid)

Description:
Biotinyl-Asp-Glu-Val-Asp-aldehyde (pseudo acid) is a biotinylated amino acid, which can be used to study the affinity of caspases and other proteases. Biotin binds to the peptide through an amide bond and the amino group on the biotin molecule reacts with reactive groups on proteins, such as lysine, cysteine, histidine, or arginine. This reaction leads to the formation of a stable link between biotin and the target protein. The biotinylated peptide can then be purified from a sample by using an affinity chromatography column that has been pre-coated with streptavidin.Biotin is not toxic because it does not bind to DNA.
