DescriptionDescription: The eBioC9B7W monoclonal antibody recognizes mouse CD223 (LAG-3, LAG3) protein expressed by activated alpha/beta-TCR bearing T cells, a subset of gamma/delta-TCR bearing T cells and a subset of NK cells. CD223 is a 70kDa type I transmembrane protein with a structure that is similar to CD4. However, a soluble form of human CD223 has been detected by ELISA in human serum, and data suggest that mouse CD223 is proteolytically cleaved in the D4 domain. This results in a 54kDa fragment containing all the extracellular domains, and a 16kDa fragment containing the intracellular and transmembrane domains. The 54kDa can remain membrane-associated or be released as soluble CD223. CD223 binds to MHC class II with higher affinity than CD4, and it is thought that this interaction is involved in the negative regulation of T-cell activation and homeostatic proliferation. Furthermore, CD223 is expressed by CD4+CD25+ regulatory T cells, and it has been suggested that CD223 may be involved in their regulatory function.Applications Reported: This eBioC9B7W (C9B7W) antibody has been reported for use in flow cytometric analysis, immunoprecipitation, and ELISA. (Please use Functional Grade purified eBioC9B7W (C9B7W), cat. 16-2231, in functional assays.).Applications Tested: This eBioC9B7W (C9B7W) antibody has been tested by flow cytometric analysis of anti-CD3 and anti-CD28-activated mouse splenocytes. This can be used at less than or equal to 0.5 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. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.This eBioC9B7W (C9B7W) antibody has also been tested by ELISA analysis of supernatant produced from mouse CD223-transfected 3A9 cells. This can be used in ELISA at 2 μg/mL for capture of the secreted form of CD223, together with the polyclonal anti-mouse CD223 (cat. 24-2232) as the detection antibody.Purity: Greater than 90%, as determined by SDS-PAGE.Aggregation: Less than 10%, as determined by HPLC.Filtration: 0.2μm post-manufacturing filtered.
