ImmuneChem’s ICP0615 detects biotinylated tyrosines on Tau and tubulin-associated proteins

February 1st, 2023

ImmuneChem’s Biotin Antibody, Agarose (ICP0615) allowed for the “direct detection of >600 distinct biotinylated tyrosine residues on Tau- and tubulin-associated proteins” (Tara et al., 2022) using the antibiotin purification strategy. These biotinylation sites revealed Tau-interacting proteins at both subcellular and amino acid levels.
