Bromo-PEG3-Alcohol With CAS NO.944251-24-5 Of PEG Linker Is Applicated In Medical Research

Introduction:  

Bromo-PEG3-Alcohol With CAS NO.944251-24-5 is a reagent with an extended spacer arm. This reagent is soluble in organic solvents such as DMSO or DMF. Once dissolved in an organic solvent, the reagent is further diluted in a non-amine containing aqueous buffer. NHS esters react efficiently with primary amino groups (-NH2) in pH 7-9 buffers to form stable amide bonds. Because antibodies and other proteins generally contain multiple lysine (K) residues in addition to the N-terminus of each polypeptide, they have multiple primary amines available as targets for labeling with NHS-activated PEG reagents.
