Biotin-PEG2-acid features a short, hydrophilic PEG spacer linking biotin to a terminal carboxylic acid group. This design enables site-specific conjugation via amine coupling while maintaining high affinity for streptavidin. The molecule exhibits excellent solubility in aqueous buffers and stability under standard handling conditions.
Biotin-PEG2-acid serves as a versatile bifunctional linker for bioconjugation, enabling site-specific labeling via its reactive carboxylic acid group and high-affinity biotin binding. The short PEG spacer enhances solubility and reduces steric hindrance, facilitating efficient conjugation to proteins, antibodies, or solid supports while maintaining functional group integrity under standard coupling conditions.
