mPEG6-NHS ester, a versatile reagent in bioconjugation and surface modification, is utilized across protein chemistry and biotechnology for a myriad of applications.

Protein and Peptide Modification: Positioned as a cornerstone in protein engineering, mPEG6-NHS ester emerges as a pivotal player for augmenting the solubility, stability, and biocompatibility of proteins and peptides. Through strategic conjugation with amino groups on lysine residues, researchers cloak proteins to shield them from immunogenic responses.

Surface Coating: In the realm of advancing biomaterials, mPEG6-NHS ester assumes a critical role in surface engineering, particularly in the coating of medical devices and implants to mitigate protein adsorption and cell adhesion. This innovative PEGylation strategy erects a hydrophilic barricade to curb fouling and enhance surface biocompatibility, thereby prolonging the functionality and longevity of implanted biomedical equipment.

Drug Delivery: Embarking on the journey towards optimized drug delivery systems, mPEG6-NHS ester shines as a linchpin in the modification of nanoparticles and liposomes. By skillfully PEGylating the carrier surface, scientists prolong circulation time in the bloodstream, elevating drug stability and bioavailability.

Diagnostic Applications: Within diagnostic realms, mPEG6-NHS ester assumes a pivotal role in amplifying the precision and reliability of assays by conjugating PEG chains to antibodies and detection molecules. This strategic modification diminishes nonspecific binding, amplifying sensitivity and accuracy in assays such as ELISAs.

The molarity calculator equation

Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2
