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".
Ki-B1R recognizes a surface antigen of 47kDa molecular weight, which appears as a single band under reducing conditions in SDS-PAGE. The epitope has not been further characterized. Antigen distribution: Isolated cells: In a test comparing the immunophenotype of rat blood lymphocytes, Ki-B1R recognised 19% + 3% of peripheral blood lymphocytes (n=5). In the same test, 18% +/- 3% of the lymphocytes stained positive for sIg, whereas 79% +/- 3% stained positive with Ki-T1R, the rat pan T-cell marker. Tissue sections: Ki-B1R shows a staining pattern similar to that of anti-rat immunoglobulin markers. Follicular mantle B- lymphocytes are strongly positive whereas staining of germinal centre B-lymphocytes depends on the immunological status of the lyphoid organ. In the gastrointestinal tract, the typical mucosa-associated lymphoid tissue (MALT) selectively displays the B-follicles, mostly those containing prominent germinal centres. The reactivity pattern of Ki-B1R does not change when applied in vivo. Specificity: Rat: mature B-lymphocytes, plasma cells. Other species: not tested.
