Description: The RM153 monoclonal antibody reacts with mouse CD153 (CD30 ligand). This 40 kDa cell surface receptor, a type II transmembrane protein, is a member of the TNF superfamily. Interaction of CD30 with CD153 plays an important role in T cell activation/costimulation. Expression of CD153 on T cells does not appear to require costimulation through CD28 and is upregulated via TCR engagement and peaks 24-48 hours after activation. Signaling through CD153 is important in costimulation of pre-activated T cells. Applications Reported: The RM153 antibody has been reported for use in flow cytometric analysis, immunoprecipitation, and immunohistochemical staining of frozen tissue sections. It has also been reported in blocking of ligand binding. (Please use Functional Grade purified RM153, cat. 16-1531, in functional assays.). Applications Tested: The RM153 antibody has been tested by flow cytometric analysis of 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. Purity: Greater than 90%, as determined by SDS-PAGE. Aggregation: Less than 10%, as determined by HPLC. Filtration: 0.2 µm post-manufacturing filtered. The ligand for CD30 is CD30L (CD153). The binding of CD30 to CD30L mediates pleiotropic effects including cell proliferation, activation, differentiation, and apoptotic cell death. CD30 has a critical role in the pathophysiology of Hodgkin ft.s disease and other CD30+ lymphomas. CD30 acts as a costimulatory molecule in thymic negative selection. In addition to its expression on Hodgkin ft.s and Reed-Sternberg cells, CD30 is also found in some non-Hodgkin ft.s lymphomas (including Burkitt ft.s lymphomas), virus-infected T and B cells, and on normal T and B cells after activation. In T cells, CD30 expression is present on a subset of T cells that produce Th2-type cytokines and on CD4+/CD8+ thymocytes that coexpress CD45RO and the IL4 receptor.
