m-PEG2000-NHS ester mPEG2000-SC; mPEG2000-Succinimidyl ester	Biochemical Assay Reagents MMP	Cancer
m-PEG2000-NHS ester (mPEG2000-SC) is a reagent with both cell adhesion inhibition and peptide conjugation functions. The NHS ester group of m-PEG2000-NHS ester forms stable amide bonds with primary amine-containing molecules (e.g., the N-terminus of MMP-2-cleavable octapeptide) to generate mPEG-peptide intermediates for liposome surface modification. When m-PEG2000-NHS ester is immobilized on a cystamine-modified gold surface, it can construct an in vitro model for cell adhesion kinetic studies, and higher PEG density and thicker layers correlate with lower cell adhesion rates. m-PEG2000-NHS ester can synthesize MMP-2-responsive PEGylated lipid conjugates to achieve MMP-triggered dePEGylation in the tumor microenvironment. m-PEG2000-NHS ester can be used in studies related to colon cancer and other conditions .
