The Abpromise guarantee
Our Abpromise guarantee covers the use of ab23553 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use 10µl for 106 cells in 100µl.
Note: ab23553 induces homotypic aggregation of B cells and inhibits anti Ig and IL4 induced proliferation. ab23553 requires the presence of both extracellular loops of TAPA1 for binding.
Not tested in other applications.
Optimal dilutions/concentrations should be determined by the end user.
FunctionMay 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.
Tissue specificityHematolymphoid, neuroectodermal and mesenchymal tumor cell lines.
Involvement in diseaseDefects 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.
Sequence similaritiesBelongs to the tetraspanin (TM4SF) family.

Flow cytometric analysis of mouse blood labelling CD81 with ab23553 at 1/10 dilution (Right). Compared with Alexa Fluor® 700 conjugated hamster IgG1 isotype control (Left). Gated on live, single lymphocytes in the presence of 10% mouse serum. Cells were stained with Alexa Fluor 700 conjugated Rat anti Mouse CD19. Data acquired on the ZE5™ Cell Analyzer.
