Bis-PEG13-NHS ester(CAT: I045985) is a homobifunctional polyethylene glycol (PEG) crosslinker bearing N-hydroxysuccinimide (NHS) esters at both ends of a 13-unit PEG spacer. The activated NHS groups react efficiently with primary amines to form stable amide bonds under mild physiological conditions. The PEG13 backbone provides hydrophilicity, flexibility, and reduced steric hindrance, while offering an intermediate linker length suitable for diverse conjugation needs. This reagent is particularly useful for protein crosslinking, bioconjugation, surface modification, and nanomaterials research, where extended and biocompatible linkers are required. Bis-PEG13-NHS ester enhances solubility, minimizes aggregation, and enables precise control over molecular spacing in advanced bioengineering applications.
