Medchemexpress LLC Biotin-PEG3-bromide | 1041766-91-9 | 95.0% | 482.43 g/mol | C18H32BrN3O5S | 50 MG
Biotin-PEG3-bromide is a biotinylated short polyethylene glycol (PEG3) linker terminated with an alkyl bromide. The bromide serves as a reactive leaving group for nucleophilic substitution or cross-coupling reactions, while the biotin enables affinity capture via streptavidin. The PEG3 spacer improves solubility and reduces steric hindrance in bioconjugation and pull-down assays.
- Reactive alkyl bromide for nucleophilic substitution and cross-coupling
- Biotin moiety enables affinity capture with streptavidin
- PEG3 spacer enhances solubility and reduces steric hindrance
- High purity (95.0%) suitable for analytical and preparative use
- Available in small quantities for research use (50 MG)
