Biotin-PEG2-NHS ester enables efficient conjugation to primary amines under physiological conditions. This water-soluble linker combines biotin’s high-affinity binding with a short PEG spacer that minimizes steric interference, delivering robust detection or immobilization in biochemical assays and protein labeling workflows.
Biotin-PEG2-NHS ester serves as a versatile bifunctional linker for protein and biomolecule conjugation. The NHS ester moiety readily reacts with primary amines under physiological conditions, enabling efficient labeling. The short PEG2 spacer enhances solubility and reduces steric hindrance, while the biotin group provides high-affinity binding to streptavidin or avidin for detection, purification, or immobilization. Ideal for antibody-drug conjugates, immunoassays, and surface functionalization.
