Store as concentrated solution. Centrifuge briefly prior to opening vial. For short-term storage (1-2 weeks), store at 4ºC. For long-term storage, aliquot and store at -20ºC or below. Avoid multiple freeze-thaw cycles.

Antigen Species



The antiserum was produced against a chemically synthesized phosphopeptide derived from the region of human FAK that contains tyrosine 861. The sequence is conserved in mouse, rat, chicken and frog.


Purified by antigen-affinity chromatography

This gene encodes a cytoplasmic protein tyrosine kinase which is found concentrated in the focal adhesions that form between cells growing in the presence of extracellular matrix constituents. The encoded protein is a member of the FAK subfamily of protein tyrosine kinases but lacks significant sequence similarity to kinases from other subfamilies. Activation of this gene may be an important early step in cell growth and intracellular signal transduction pathways triggered in response to certain neural peptides or to cell interactions with the extracellular matrix. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jun 2017]

GTX24804 WB Image

WB (peptide competition) analysis of 3T3-L1 cells stimulated with 50 ng/ml LIF for 15 minutes (Lane 2-4) using GTX24804 FAK (phospho Tyr861) antibody prior incubated with the phosphopeptide immunogen (Lane 1), or genertic phosphopeptide (Lane 2), the non-phosphopeptide corresponding to generic phosphoserine-containing peptide (Lane 3), or no peptide (Lane 4).. The data show that only the immunogen phosphopeptide blocks the signal, demonstrating the specificity of the antibody.
