Synthetic peptide corresponding to Human Eph receptor A4 aa 875-904 (C terminal) conjugated to Keyhole Limpet Haemocyanin (KLH).
Protein kinases are enzymes that transfer a phosphate group from a phosphate donor, generally the g phosphate of ATP, 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. With more than 500 gene products, the protein kinase family is one of the largest families of proteins in eukaryotes. The family has been classified in 8 major groups based on sequence comparison of their tyrosine (PTK) or serine/threonine (STK) kinase catalytic domains. The tyrosine kinase (TK) group is mainly involved in the regulation of cell-cell interactions such as differentiation, adhesion, motility and death. There are currently about 90 TK genes sequenced, 58 are of receptor protein TK (e.g. EGFR, EPH, FGFR, PDGFR, TRK, and VEGFR families), and 32 of cytosolic TK (e.g. ABL, FAK, JAK, and SRC families).
Our Abpromise guarantee covers the use of ab5396 in the following tested applications.
|WB||1/1000. Detects a band of approximately 108 kDa (predicted molecular weight: 118 kDa).
We recommend using CHAPS lysis buffer rather than RIPA, Invitrogen NuPage gel system, blotting on PVDF membrane, blocking 30' in 10% Fetal Bovine Serum, 3% BSA, 0.3% Tween 20 in 1X PBS - please see Abreview for further information (published on 24th July, 2006).
|IHC-P||1/25 - 1/100.|
Incubation time was overnight at 4°C. Blocking/Dilution buffer: 5% NFDM/TBST.
Blocking/Dilution buffer: 5% NFDM/TBST.
Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human breast carcinoma tissue labeling Eph receptor A4 with ab5396 at dilution 1/25. Tissue was fixed with formaldehyde and blocked with 3% BSA for 0.5 hour at 37°C; heat mediated antigen retrieval was performed using a citrate buffer (pH6). Samples were incubated with primary antibody (1/25) for 1 hour at 37°C. A Peroxidase-conjugated Goat anti-rabbit polyclonal (ready to use) was used as the secondary antibody.
