Biotin-PEG3-Bromide
Based on 1 Customer Validation
Biotin-PEG3-Bromide is a short PEG linker featuring a biotin group and a bromide. The bromide is a halogen which is easily displaced by nucleophiles such as alcohols or amines. Alternatively, bromide can be applied in a number of cross-coupling reactions such as in a Suzuki reaction. Biotin is useful for affinity-based applications such as pull-down assays or for ligating with streptavidin proteins.
