Biotin-PEG-CHO (Biotin-PEG-Aldehyde, Biotin-PEG-ALD) refers to a compound where biotin is linked to a polyethylene glycol (PEG) spacer terminated with an aldehyde functional group (-CHO). Biotin is a vitamin B derivative that binds specifically and with high affinity to avidin and streptavidin. It serves as a versatile tag for detection, purification, or immobilization of biotinylated molecules. Polyethylene glycol (PEG) is a flexible and hydrophilic linker that provides solubility and reduces nonspecific interactions in biological systems. The aldehyde group is reactive towards primary amines (-NH2), forming a Schiff base or imine linkage under mild conditions. This reactivity is commonly used in bioconjugation reactions.
