Protein kinases are enzymes that transfer a phosphate group from a phosphate donor onto an acceptor amino acid in a substrate protein. By this basic mechanism, protein kinases mediate most of the signal transduction in eukaryotic cells, regulating cellular metabolism, transcription, cell cycle progression, cytoskeletal rearrangement and cell movement, apoptosis, and differentiation. The protein kinase family is one of the largest families of proteins in eukaryotes, classified in 8 major groups based on sequence comparison of their tyrosine (PTK) or serine/threonine (STK) kinase catalytic domains. Epidermal Growth factor receptor (EGFR) is the prototype member of the type 1 receptor tyrosine kinases. EGFR overexpression in tumors indicates poor prognosis and is observed in tumors of the head and neck, brain, bladder, stomach, breast, lung, endometrium, cervix, vulva, ovary, esophagus, stomach and in squamous cell carcinoma.

Recognizes the sequence of Ala351-Asp364 of human EGF receptor, Mr 180kDa, (based on numbering without the signal peptide) (Wu et al., 1989).

Immunoprecipitation:
4 μg of a previous lot immunoprecipitated EGF receptor from 500 μg of A431 RIPA lysate.

Immunocytochemistry:
5 μg/mL of previous lots of the antibody showed positive immunostaining for EGF receptor in A431 cells fixed with 4% paraformaldehyde followed by 100% methanol.

Evaluatd by RIPA lysates from human A431 cells under reducing conditions.

Western Blot Analysis:
0.5-2 μg/mL of this antibody detected EGF receptor in RIPA lysates from human A431 cells under reducing conditions.

Replaces: 04-337; 04-338

Purified mouse monoclonal IgG2a in storage buffer (0.1 M Tris-glycine, pH 7.4, 0.15 M NaCl, 0.05% sodium azide). Frozen solution.
Format: Purified
Protein G Purified

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