Cell Signaling - Antibodies for the analysis of signal transduction pathways

Antibodies for the analysis of signal transduction pathways

Cell signaling is a complex process that enables communication between cells and the transduction of a signal from the cell surface all the way to the nucleus. In order to efficiently transmit the signal a myriad of different proteins are required ranging from growth factors/ligands that bind to cell surface receptors to transcription factors altering gene expression patterns. Changes in the levels of biochemical molecules, like nitric oxide and cyclic GMP, and modifications, such as phosphorylation, ubiquitination, neddylation, and sumoylation, are the main ways to convey these signals.

Extensive research has enabled the elucidation of many cell signaling mechanisms and has resulted in the mapping of entire cell signaling pathways. These pathways, which are often named after their main kinase protagonists (e.g. MAP kinase pathway, PI3K-Akt pathway), feature sophisticated feedback loops and due to extensive cross-talk should be viewed as part of a larger network rather than a simplistic single pathway. Misregulation of cell signaling pathways has been implicated in a variety of diseases including cancer, type II diabetes and Parkinson’s disease. Based on this it is not surprising that a lot of effort into developing targeted inhibitors against specific cell signaling molecules or protein interactions.

For your cell signaling research, Bio-Rad offers antibodies for the characterization of kinases, phosphatases, phosphorylated proteins, SUMO mediated signaling and ubiquitin mediated signaling by ELISA, flow cytometry, immunofluorescence, immunohistochemistry, immunoprecipitation and western blotting.

Featured rabbit anti-FAK antibody (AHP1106)

Focal Adhesion Kinase (FAK), also known as PTK2 protein tyrosine kinase 2 (PTK2), is a non-receptor tyrosine kinase that plays an essential role in regulating cellular processes such as cell migration, spreading and cell adhesion. Its hypothesized involvement in cancer cell proliferation and well documented interactions with proto-oncogenes (e.g. EGFR, VEGFR) and tumor suppressor proteins (e.g. p53) make it an ideal target for the development of novel cancer treatments. 

Rabbit anti-FAK antibody (AHP1106) has been tested in Immunohistochemistry-paraffin and detects an epitope within the internal region of FAK.

Applications: Immunohistochemistry-paraffin

Featured mouse anti-SSH3 antibody (MCA3868Z)

The slingshot homologs phosphatase family consists of three members (SSH1, SSH2 and SSH3), which have been implied to control actin dynamics via dephosphorylating actin-depolymerizing factor (ADF)/cofilin. The exact role of SSH3 remains somewhat elusive as is the importance of the phosphorylation of SSH3 on serine residue 37. Mouse anti-SSH3 antibody (clone 6F9) has been raised against a recombinant protein corresponding to amino acids 293 - 392 of human SSH3 and recognizes a protein of approximately 75 kDa in Western Blotting. The antibody has also been tested in Immunofluorescence and Immunohistochemistry- paraffin (antigen retrieval using heat treatment should be performed).

Applications: Immunofluorescence, Immunohistochemistry-paraffin, Western Blotting
