Invitrogen™ Phosphoserine/threonine/tyrosine Polyclonal Antibody 

Description

This antibody detects pS, pT and pY amino acids with very low cross reactivity to their non-phosphorylated variants.

There are three amino acids that are typically phosphorylated in eukaryotes: serine, threonine, and tyrosine. These phosphoric acid esters can be used as an identifier in the analysis of peptides, proteins, and enzymes. Antibodies that specifically recognize phosphorylated residues have proved to be invaluable to the study of biochemical pathways in which they function.
