42 kDa

ERK2 is activated by MEK2, which phosphorylates neighboring threonine 183 and tyrosine 185 residues. ERK2 is a serine/threonine kinase that phosphorylates MAP2 and myelin basic protein. This kinase is an important proximal component of the MAP kinase pathway involved in transeitting the signals from growth factors, neurotransmitters and hormones at the cell surface to the transcriptional events in the nucleus.

Other species cross reactivity is unknown.

This antibody recognizes MAP kinase encoded by the mapk gene, Mr 42 kDa.

HPLC purified murine recombinant MAP Kinase. Clone 1B3B9

Anti-MAP Kinase 2/Erk2 Antibody, clone 1B3B9 is an antibody against MAP Kinase 2/Erk2 for use in IP & WB.

Immunoprecipitation:
4 μg of a previous lot immunoprecipitated MAP Kinase 2/Erk2 from a RIPA lysate from mouse 3T3 cells. Boil the cell lysate and let cool before adding the antibody, as this antibody only binds to denatured MAP Kinase.

Format: Purified

Purified mouse monoclonal IgG2a in buffer containing PBS with 0.05% sodium azide. Store frozen at -20°C, avoid freeze thaw cycles.

Stable for 1 year at -20ºC from date of receipt.

Handling Recommendations:
Upon receipt, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.

Control
Positive Antigen Control: Catalog #12-301, non-stimulated A431 cell lysate. Add 2.5µL of 2-mercaptoethanol/100µL of lysate and boil for 5 minutes to reduce the preparation. Load 20µg of reduced lysate per lane for minigels.

Routinely evaluated in RIPA lysates from human A431 carcinoma cells, mouse 3T3 fibroblasts, or rat L6 cells.

Western Blot Analysis:
0.5-2 µg/mL of this lot detected MAP Kinase 2/Erk2 in RIPA lysates from human A431 carcinoma cells. A previous lot detected MAP Kinase in mouse 3T3 fibroblasts and rat L6 cells.

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.
