General description
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.
Specificity
Recognizes the sequence of Ala351-Asp364 of human EGF receptor, Mr 180kDa, (based on numbering without the signal peptide) (Wu et al., 1989).
Immunogen
A431 membrane proteins
Application
Anti-EGFR Antibody, clone LA22 is an antibody against EGFR for use in IC, IP & WB.
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.

L-arginine is metabolized to nitric oxide (NO) by NO synthase (NOS), or to urea and L-ornithine by arginase. L-ornithine contributes to vascular remodeling in pulmonary hypertension via metabolism to polyamines and proline. Previously we found that cytokines upregulate both NOS
