The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use 10µl for 106 cells. Induces homotypic aggregation of B cells and inhibits anti Ig and IL4 induced proliferation. It requires the presence of both extracellular loops of TAPA1 for binding.
ab18473-Armenian Hamster monoclonal IgG, is suitable for use as an isotype control with this antibody.
Use at an assay dependent concentration.
May play an important role in the regulation of lymphoma cell growth. Interacts with a 16-kDa Leu-13 protein to form a complex possibly involved in signal transduction. May acts a the viral receptor for HCV.
Hematolymphoid, neuroectodermal and mesenchymal tumor cell lines.
Defects in CD81 are the cause of immunodeficiency common variable type 6 (CVID6) [MIM:613496]; also called antibody deficiency due to CD81 defect. CVID6 is a primary immunodeficiency characterized by antibody deficiency, hypogammaglobulinemia, recurrent bacterial infections and an inability to mount an antibody response to antigen. The defect results from a failure of B-cell differentiation and impaired secretion of immunoglobulins; the numbers of circulating B cells is usually in the normal range, but can be low.
