Our Anti-ERK/MAPK (Thr202/Tyr204) rabbit polyclonal phosphospecific primary antibody from PhosphoSolutions is produced in-house. It detects human, mouse, and rat ERK/MAPK (Thr202/Tyr204) and is antigen affinity purified from pooled serum. It is great for use in WB, IHC, ICC.
Immunostaining of neurons in the frontal cortex of saline treated mouse brain identifying cytoplasmic and nuclear staining of ERK/MAPK when phosphorylated at Thr202/Tyr204 (cat. p160-2024, red, 1:500). The intense nuclear staining of a few neurons shows stimulation of the neuron resulting in translocation of the protein. The blue is staining nuclei with DAPI. Photo courtesy of Robert Wine.
Extracellular-Signal Regulated Kinase/Mitogen-Activated Protein Kinase (ERK/MAPK) is an integral component of cellular signaling during mitogenesis and differentiation of mitotic cells and also is thought to play a key role in learning and memory (Adams and Sweatt, 2002; Ahn, 1993; Tanoue and Nishida, 2003; Johnson and Lapadat, 2002). The activity of this kinase is regulated by dual phosphorylation at Thr202 and Tyr204 (Ahn, 1993).
Antigen Affinity Purified from Pooled Serum
Polyclonal
IgG
ICC, IHC, WB
Rabbit
MAPK1/2
42/44 kDa
Synthetic phospho-peptide corresponding to amino acid residues surrounding Thr202/Tyr204 of rat ERK/MAPK conjugated to keyhole limpet hemocyanin (KLH).
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.
Liquid
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.
WB: 1:1000
IHC: 1:100-1:500
ICC: 1:100-1:250
Unconjugated
Specific for endogenous levels of the ~42 - 44 kDa ERK/MAPK protein phosphorylated at Thr202 and Tyr204. Immunolabeling is completely eliminated by treatment with λ-phosphatase.
Phosphorylated
Thr202, Tyr204
Western blots performed on each lot.
