SPE Sorbents

Supplier: G-Biosciences

These cross-linking agents contain at least two reactive groups that are reactive towards numerous groups, including sulphydryls, amines and carbohydrates, and create chemical covalent bonds between two or more molecules. Functional groups that can be targeted with cross-linking agents are primary amines, carboxyls, sulfhydryls, carbohydrates and carboxylic acids. Protein molecules have many of these functional groups and therefore proteins and peptides can be readily conjugated using cross-linking agents.
