Applications
Our Abpromise guarantee covers the use of ab2391 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
| Application | Abreviews | Notes |
|---|---|---|
| Flow Cyt | 1/200. ab171870 - Rabbit polyclonal IgG, is suitable for use as an isotype control with this antibody.
|
|
| ICC/IF | 1/200. See Abreview | |
| ELISA | Use a concentration of 0.5 - 1 µg/ml. | |
| WB | Use a concentration of 1 µg/ml. | |
| IHC-P | Use at an assay dependent concentration. | |
| IHC-Fr | 1/100. Fix with acetone -20°C for 10 min (provides a better signal than unfixed tissue; PFA 4% abolishes the signal). Incubate primary for 24h at 4°C. Use amplification (indirect IF). |
Target
-
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.
-
Post-translational
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.
Not O-glycosylated. -
Cellular localizationSecreted and Cell membrane.

Immunohistochemistry (Frozen sections) - Anti-TRAP/CD40L antibody (ab2391)This image is courtesy of an Abreview submitted by Jens Schmidtab2391 at a 1/100 dilution staining TRAP/CD40L from human inflamed muscle tissue sections by immunohistochemistry (frozen sections). The tissue was acetone fixed (this provides a better result than unfixed tissue) and then incubated with the antibody for 24 hours at 4 °C. Alexa-Fluor ® 594 was used as the secondary antibody.
