m-PEG2000-NHS ester
Based on 1 Customer Validation
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.

Biologische Aktivität
|
MMP-2 |
m-PEG2000-NHS ester (10 μL/h; 8 h) creates a PEG thickness gradient (0 to 16 nm) that reduces the adhesion rate of BAVEC-1 cells, with near-zero adhesion rate at the 16 nm thick gradient center when delivered into a 3% agarose gel overlay on cystamine-coated gold substrates[1].
m-PEG2000-NHS ester (1:5 molar ratio; overnight, 2 h, 48 h) successfully forms an amide bond with the N-terminus of an MMP-2-cleavable octapeptide, which is then conjugated to DOPE to create an MMP-2-responsive PEG-lipid conjugate[2].
