Product Specific Information

Description: This M4G3LN monoclonal antibody recognizes human and mouse Bruton's tyrosine kinase (also known as BTK, agammaglobulinaemia tyrosine kinase, B-cell progenitor kinase)/interleukin-2-inducible tyrosine kinase (also known as ITK, T-cell-specific kinase, Tyrosine-protein kinase Lyk) when phosphorylated on Y551 and Y511, respectively.

In addition to Src family and SYK family kinases, B cells and T cells express a third family of receptor-proximal kinases called the Tec kinase family. The B cell-specific Tec family kinase is BTK; T cells express ITK as well as Tec and Rlk. Tec family kinases play an indispensable role in activation of phospholipase C and activation of calcium-dependent signaling cascades following antigen receptor triggering. BTK has been implicated in propagating signals downstream of LPS-TLR4 in B cells via signaling through the TLR4 co-receptor RP105/CD180. Mice congenitally lacking BTK or ITK show profound defects in B cell or T cell development and signaling, respectively. People with mutations or deletions in BTK suffer from X-linked agammaglobulinemia and X-linked immunodeficiency.

Specificity of this M4G3LN clone was determined by ELISA, flow cytometry, and western blotting.

Applications Reported:This M4G3LN antibody has been reported for use in intracellular staining followed by flow cytometric analysis.

Applications Tested: This M4G3LN antibody has been pre-titrated and tested by intracellular staining followed by flow cytometric analysis of stimulated normal human peripheral blood cells. This can 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.

Staining Protocol: All protocols work well for this monoclonal antibody. Use of Protocol A: Two-step protocol: intracellular (cytoplasmic) proteins allows for the greatest flexibility for detection of surface and intracellular (cytoplasmic) proteins. Use of Protocol B: One-step protocol: intracellular (nuclear) proteins is recommended for staining of transcription factors in conjunction with surface and phosphorylated intracellular (cytoplasmic) proteins. Protocol C: Two-step protocol: Fixation/Methanol allows for the greatest discrimination of phospho-specific signaling between unstimulated and stimulated samples, but with limitations on the ability to stain specific surface proteins (refer to "Clone Performance Following Fixation/Permeabilization" located in the BestProtocols Section under the Resources tab online). All Protocols can be found in the Flow Cytometry Protocols: "Staining Intracellular Antigens for Flow Cytometry Protocol" located in the BestProtocols® Section under the Resources tab online.

Excitation: 633-647 nm; Emission: 660 nm; Laser: Red Laser.

Filtration: 0.2 µm post-manufacturing filtered.
