Biotin-PEG2-alkyne CAS:2227450-68-0 plays a key role in click chemistry biotinylation, facilitating the marking of azide-containing substances using biotin in a copper-activated click reaction. This marking permits binding with avidin or streptavidin, furthering purification and detection. The compound’s structure features a PEG2 chain, effectively separating the biotin segment and target molecule for efficient streptavidin binding, while also enhancing water solubility for improved conjugation.
AxisPharm offers 5000+ PEG Linkers with high purity. Different kinds of PEG Reagents may be available by custom synthesis.
