Recombinant Human CD40 Ligand/CD154/CD40L/TNFSF5 Protein (RP00329)



Product nameRecombinant Human CD40 Ligand/CD154/CD40L/TNFSF5 Protein
Catalog No.RP00329
DescriptionRecombinant Human CD40 Ligand/CD154/CD40L/TNFSF5 Protein is produced by Human Cell expression system. The target protein is expressed with sequence (Met113-Leu261) of human CD40 Ligand/CD154/CD40L/TNFSF5 (Accession #P29965).
Bio-ActivityMeasured in a cell proliferation assay using B cell-enriched peripheral blood mononuclear cells (PBMC) in the presence of IL-4. The ED50 for this effect is 1-3 μg/mL in the presence of 20 ng/mL of recombinant human IL-4.
Swiss portP29965
Gene ID959
This protein is expressed on the surface of T cells. It regulates B cell function by engaging CD40 on the B cell surface. A defect in this gene results in an inability to undergo immunoglobulin class switch and is associated with hyper-IgM syndrome.
