Biotin-PEG3-bromide is a biotinylated short polyethylene glycol (PEG3) linker with a terminal alkyl bromide. It is used to introduce a biotin affinity tag onto molecules via nucleophilic substitution or cross-coupling reactions, enabling streptavidin-based capture, detection, and pull-down workflows in chemical biology and bioconjugation studies.
- Reactive alkyl bromide suitable for nucleophilic substitution and cross-coupling reactions.
- Biotin moiety enables high-affinity capture with streptavidin/avidin reagents.
- Short PEG3 spacer improves solubility and reduces steric hindrance.
- High solubility in DMSO allows preparation of concentrated stock solutions.
- Powder stable at -20°C; follow recommended storage for solutions to maintain integrity.
AdipoGen 4-ITCB-MPO-pyridinium bromide
Chemical. CAS 155862-90-1. Formula C23H18BrN3O2S. MW 480.38. Synthetic. New class of highly photostable, water soluble fluorescent labels with large Stokes shift, high QY in aqueous media and pH tolerance. Major disadvantage rel. low extinction coefficient.
