The Best Protein Labeling 2023. Web protein labeling reagents are reactive dyes that attach to a specific functional group (i.e., amine or thiol) on a target biomolecule allowing for its subsequent detection or purification. Antibody labeling with fluorophores and biotin.

Removal of bsa and other stabilizers is required prior to labeling Web labeling a protein is only the first step. Detection systems help you figure out where, how much and what role the protein plays in the cell.
