Our Abpromise guarantee covers the use of ab237257 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
FunctionReceptor for TNFSF5/CD40LG.
Tissue specificityB-cells and in primary carcinomas.
Involvement in diseaseDefects in CD40 are the cause of hyper-IgM immunodeficiency syndrome type 3 (HIGM3) [MIM:606843]; also known as hyper-IgM syndrome 3. HIGM3 is an autosomal recessive disorder which includes an inability of B cells to undergo isotype switching, one of the final differentiation steps in the humoral immune system, an inability to mount an antibody-specific immune response, and a lack of germinal center formation.
Sequence similaritiesContains 4 TNFR-Cys repeats.
Cellular localizationSecreted and Cell membrane.

Flow cytometry staining of C57 BL/6 mouse splenocytes with ab237257 (right) or Rabbit IgG (monoclonal) Alexa Fluor® 488 (ab199091) isotype (left). Cells were incubated for 30 min on ice in 1x PBS containing 10 μg/ml anti CD16/CD32 and 10 % normal goat serum to block FC receptors and non-specific protein-protein interaction followed by the antibody (ab237257) or Rabbit IgG (monoclonal) Alexa Fluor® 488 (ab199091) isotype (1x 106 in 100μl at 1 µg/ml (1/500)) for 30 min on ice. The cells were simultaneously stained with CD19.
Acquisition of >30000 events were collected using a 50 mW Blue laser (488nm) and 530/30 bandpass filter. Events were gated on live single cells.
