4A4
Isotype:
IgG1
Background Information:
The identification of protein phosphorylation as a regulatory mechanism originated from studies by Fischer and Krebs in the mid 1950s that later earned them the 1992 Nobel prize. It is the major mechanism for the regulation of diverse cellular processes including cell division, protein synthesis, transcriptional regulation and neurotransmission. The steady state phosphorylation of any given substrate is governed by the opposing activities of kinases and phosphatases. It is now believed that a third of all eukaryotic cellular proteins are phosphorylated and that the majority of all phosphorylation events occur on serine and threonine residues (greater than 95%).
Species Reactivity:
Vertebrates
Control:
Suggested Positive Control: Cat.# 12-628, Calyculin A/Okadaic-treated A431 cell lysate is recommended as a positive control for western immunoblotting. Aliquot as desired, refreeze immediately, and store at –20ºC. The lysate is stable for 6 months at –20ºC.
Quality Assurance:
Routinely evaluated by immunoblot analysis on lysate from Calyculin A/Okadaic-treated human A431 carcinoma cells.
Purification Method:
Protein G-Sepharose™ chromatography
Presentation:
1 mL of PBS
Storage Conditions:
2 years at -20°C from date of shipment.
