Protein Labeling Kits

Protein labeling kits provide a convenient means for covalently attaching conjugates, labels, or moieties to existing protein samples. Modification with conjugates function to enhance proteins for detection (fluorophores or enzyme labels), for purification (biotin, agarose, beads and microparticles), or for other functions, like drug delivery (BSA and other carrier molecules). Labeling methods may involve chemically reactive functional groups (maleimide, succinimidyl esters) or via enzymatic reactions. Consider the chemical labeling method when choosing an appropriate protein labeling kit. Commercial protein conjugation and labeling kits are ready-to-use and contain the necessary reagents for the application.
