Mitogen Activated Protein Kinases (MAPKs) play pivotal roles in mediating signal transduction from the cell surface to the nucleus. These kinases are encoded by distinct genes and together form a family of kinases whose activation is dependent upon dual phosphorylation on specific threonine and tyrosine residues. In yeast, a number of different MAP Kinases have been identified and are activated by distinct signaling pathways. In mammalian cells, the best characterized sub-group of the MAP Kinase family are the Extracellular Signal Regulated Kinases (ERKs). To date, at least 4 distinct ERKs have been identified including: ERK1 (p44/p43), ERK2 (p42/p43), ERK3 (p62), and ERK4 (p45). Analysis of cDNAs encoding MAP Kinase suggest that numerous other ERKs may exist. MAP Kinase has been shown to phosphorylate numerous proteins including: RSK (4) , c-Fos, c-Jun, c-Myc, c-raf, MAP2, and MEK (5) . MAP Kinase is directly activated when phosphorylated by MEK and indirectly stimulated by many factors (6, 7, 8) .

Applications:

Recommended Dilution:
ELISA: 0.1–1ug/ml
Immunoprecipitation (11) : 2–5ug
Western Blotting (9, 10) : 1ug/ml

Optimal dilutions to be determined by the researcher.

Storage and Stability:
Store product at 4°C if to be used immediately within two weeks. For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20°C. Aliquots are stable at -20°C for 12 months after receipt. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Note: Sodium azide is a potent inhibitor of peroxidase and should not be added to HRP conjugates.
For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.

Note: Applications are based on unconjugated antibody.
