Our Anti-PTPH1 (Ser459) rabbit polyclonal phosphospecific primary antibody from PhosphoSolutions is produced in-house. It detects human and mouse PTPH1 (Ser459) and is antigen affinity purified from pooled serum. It is great for use in WB.
Western blot of mouse testicular lysate showing specific immunolabeling of the ~104 kDa PTPH1 phosphorylated at Ser459 in the first lane (-). Phosphospecificity is shown in the second lane (+) where the immunolabeling is completely eliminated by lysate treatment with lambda phosphatase (λ-Ptase , 400 units/100ul lysate for 30 minutes, RT).

Bulk Order Anti-PTPH1 (Ser459) Antibody
Protein-tyrosine Phosphatase H1 (PTPH1) has recently been identified as a specific p38γ MAPK phosphatase which is mediated through PDZ interaction (Hou et al., 2010). Ras has been demonstrated to increase both p38γ and PTPH1 protein expression, and there is a coupling of increased p38γ and PTPH1 protein expression in primary colon cancer tissues (Hou et al., 2010). Phosphorylation of PTPH1 at Ser-459 leads to PTPH1 stabilization, which plays an important role in Ras oncogenesis and stress response (Hou et al., 2012). Additionally, phosphorylation of PTPH1 Ser-459 reveals a novel mechanism by which MAPK signals through PTPH1 to regulate cellular response (Hou et al., 2012).
Antigen Affinity Purified from Pooled Serum
Synthetic phospho-peptide corresponding to amino acid residues surrounding Ser459 of human PTPH1, conjugated to keyhole limpet hemocyanin (KLH).
Bovine, Canine, Non-Human Primate, Sheep
Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.
Prepared from pooled rabbit serum by affinity purification via sequential chromatography on phospho and non-phosphopeptide affinity columns.
10 mM HEPES (pH 7.5), 150 mM NaCl, 100 µg per ml BSA and 50% glycerol.
Specific for endogenous levels of the ~104 kDa PTPH1 protein phosphorylated at Ser459. The immunolabeling is completely eliminated by treatment with λ-phosphatase.
