T-bet/TBX21 Antibody (1091005) [Unconjugated]

Western Blot shows lysates of Jurkat human acute T cell leukemia cell line, SUP‑T1 human T cell lymphoblastic lymphoma cell line and Daudi human Burkitt's lymphoma cell line. PVDF membrane was probed with 0.5 µg/ml of Mouse Anti-Human T‑bet/TBX21 Monoclonal Antibody (Catalog # MAB11637) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for T‑bet/TBX21 at approximately 58 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.

Simple Western shows lysates of Daudi human Burkitt's lymphoma cell line, loaded at 0.5 mg/ml. A specific band was detected for T‑bet/TBX21 at approximately 54 kDa (as indicated) using 20 µg/mL of Mouse Anti-Human T‑bet/TBX21 Monoclonal Antibody (Catalog # MAB11637). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Background

T-box expressed in T cells (T-bet), also known as T-box transcription factor TBX21, is a 62 kDa member of the T-box family of transcription factors and the Tbr1 subfamily. Human T-bet is 535 amino acids in length and contains a T-box DNA binding domain (aa 136-327). Human T-bet shares 88% aa sequence identity with mouse T-bet. T-bet is a nuclear protein highly apparent in Th1-cells. Northern blot analysis revealed that it is also expressed in lung, thymus and spleen. Functionally, T-bet controls the expression of the Th1 cytokine, IFN gamma , and initiates Th1 lineage development from naïve Th precursor cells by both activating Th1 genetic programs and by repressing the opposing Th2 programs.

FAQs for T-bet/TBX21 Antibody (MAB11637). (Showing 1 - 1 of 1 FAQ).

1. Do you make a Tbx21 ab for FACS for porcine?
   • We have not tested our Tbx21 antibodies for porcine, however you might like to test NBP1-43298 as part of our Innovators Reward Program. This is gained from testing a product on a species or application that we have not yet tested. I have carried out a blast to check the % homology between the pig protein and human protein, this is 94% and our lab recommends use if the % homology is 85% or above.
