Product Specific Information

Description: This 4D10.1 monoclonal antibody recognizes human Syk, a 72-kDa member of the Syk/ZAP-70 family of non-receptor protein tyrosine kinases. Syk is expressed most highly in B cells, with lower expression in immature thymocytes, mast cells, and platelets. Syk can also be detected in fibroblasts, epithelial cells, hepatocytes, endothelial cells, and neuronal cells. This protein is a major component of signaling cascades downstream of the B and T cell antigen receptors and plays an essential role in lymphocyte development. Upon recruitment to immunoreceptor tyrosine-based activation motifs (ITAMs) on the antigen receptors, Syk is activated by phosphorylation on multiple tyrosines. Once activated, Syk phosphorylates proteins such as phospholipase C gamma and BLNK/SLP-65. Finally, abnormal Syk expression has been linked to tumor cell migration and invasion in several cancers.

Applications Reported: This 4D10.1 antibody has been reported for use in intracellular staining followed by flow cytometric analysis.

Applications Tested: This 4D10.1 antibody has been pre-diluted and tested by intracellular staining followed by flow cytometric analysis of normal human peripheral blood cells using the Foxp3/Transcription Factor Staining Buffer Set (Product # 00-5523-00) and protocol. Please refer to "Staining Intracellular Antigens for Flow Cytometry, Protocol B: One step protocol for intracellular (nuclear) proteins" located at Flow Protocols . This may be used at 5 µL (0.125 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test.

Excitation: 488 nm; Emission: 519 nm; Laser: Blue Laser.

Target Information

Spleen tyrosine kinase (SYK), along with ZAP70, are cytoplasmic tyrosine kinases that are viewed as potential druge targets for allergic disorders and autoimmune diseases. SYK may also play a role in cancer. Syk translocates to the plasma membrane upon B cell antigen receptor (BCR) or the high-affinity IgE receptor (FcepsilonRI) triggering, and phosphorylates downstream adaptor proteins, thereby providing docking sites for initiation of subsequent signaling pathways, such as calcium mobilization, cytoskeleton remodeling, or transcription of specific genes. Syk binds to the receptor assemblies through interactions of its pair of SH2 domains with ITAM motives of the receptor, which have been phosphorylated by Src-family kinases. These kinases also help to activate Syk by phosphorylation of its activation loop.
