SKU: AP15974 Category: OPSS-Poly(L-Glutamic Acid)

OPSS-Poly(L-Glutamic Acid), MW 2.5K (OPSS-pGlu, MW 2,500)

Structure: Negatively charged synthetic polyamino acid with γ‑peptide‑linked L‑glutamic acid units, one terminal orthopyridyl disulfide (OPSS) group, and one carboxyl (COOH) per repeat unit.
Key Properties: White/off‑white crystalline solid; soluble in water (alkaline), dichloroacetic acid, chloroform, warm DMF, and dioxane.
Core Function: OPSS selectively reacts with free thiols (‑SH) to form reversible disulfide bonds, enabling thiol‑specific bioconjugation.
Applications: Drug conjugation, protein labeling, reversible surface modification, layer‑by‑layer assembly, and stimuli‑responsive delivery systems.
Storage: −20 °C.
