Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to
worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting
immunostaining in relation to complex human pathologies.
TCR Screening Services
Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding.
Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".
Mouse Monoclonal [clone B199.2] (IgG2b) to Human KLRB1 / CD161
Human KLRB1 / CD161
Human (tested or 100% immunogen sequence identity)
IgG2b Monoclonal [B199.2]
Protein G purified
Specificity and Use
Recognizes the human CD161 cell surface antigen, expressed by almost all NK cells and with a small subset of CD3+ve T cells. CD161 is a homodimeric cell surface protein, comprising two chains of 40-44kD. Clone 3H1911 recognizes a similar epitope to the DX9 monoclonal antibody.
Flow Cytometry: Neat. The applications listed have been tested for the unconjugated form of this product. Other forms have not been tested.
Lyophilized from PBS, pH 7.2, 0.1% sodium azide, 1% BSA.
Short term: 4°C. Long term: Store at -20°C. Avoid freeze-thaw cycles.
Plays an inhibitory role on natural killer (NK) cells cytotoxicity. Activation results in specific acid sphingomyelinase/SMPD1 stimulation with subsequent marked elevation of intracellular ceramide. Activation also leads to AKT1/PKB and RPS6KA1/RSK1 kinases stimulation as well as markedly enhanced T-cell proliferation induced by anti-CD3. Acts as a lectin that binds to the terminal carbohydrate Gal-alpha(1,3)Gal epitope as well as to the N-acetyllactosamine epitope.
