A polyclonal antibody for detection of NF?B-p105/p50 phospho Ser337) from Human, Mouse, Rat. This NF?B-p105/p50 phospho Ser337) antibody is for WB, IHC-P, IF, ELISA. It is affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogenand is unconjugated. The antibody is produced in rabbit by using as an immunogen synthesized peptide derived from human NF?B-p105/p50 around the phosphorylation site of S337
