The Abpromise guarantee
Our Abpromise guarantee covers the use of ab273509 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use at an assay dependent concentration.
Use at an assay dependent concentration.
FunctionMediates B-cell proliferation in the absence of co-stimulus as well as IgE production in the presence of IL-4. Involved in immunoglobulin class switching.
Release of soluble CD40L from platelets is partially regulated by GP IIb/IIIa, actin polymerization, and an matrix metalloproteinases (MMP) inhibitor-sensitive pathway.
Tissue specificitySpecifically expressed on activated CD4+ T-lymphocytes.
Involvement in diseaseDefects in CD40LG are the cause of X-linked immunodeficiency with hyper-IgM type 1 (HIGM1) [MIM:308230]; also known as X-linked hyper IgM syndrome (XHIM). HIGM1 is an immunoglobulin isotype switch defect characterized by elevated concentrations of serum IgM and decreased amounts of all other isotypes. Affected males present at an early age (usually within the first year of life) recurrent bacterial and opportunistic infections, including Pneumocystis carinii pneumonia and intractable diarrhea due to cryptosporidium infection. Despite substitution treatment with intravenous immunoglobulin, the overall prognosis is rather poor, with a death rate of about 10% before adolescence.
Sequence similaritiesBelongs to the tumor necrosis factor family.
modificationsThe soluble form derives from the membrane form by proteolytic processing.
N-linked glycan is a mixture of high mannose and complex type. Glycan structure does not influence binding affinity to CD40.
Cellular localizationSecreted and Cell membrane.

Flow cytometric analysis of human peripheral blood mononuclear cell (PBMC) treated with 50ng/mL PMA and 500ng/mL Ionomycin for 6h cells labelling TRAP/CD40L with ab273499 at 1/600 dilution (0.1µg) (Right panel) compared with a Rabbit monoclonal IgG (ab172730) isotype control (Left panel). Goat anti rabbit IgG (Alexa Fluor® 488, ab150077) at 1/2000 dilution was used as the secondary antibody.
Gated on viable cells.
This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab273499).
