Product Description
Cat
IMP-10356
Official Symbol
Cd40
Product Overview
Recombinant Mouse CD40/TNFRSF5 protein (Val24-Arg193) with a Human IgG1 (Pro100-Lys330) Fc tag and 6×His tag at C-terminus was expressed in Mouse myeloma cell line.
Description
This gene is a member of the TNF-receptor superfamily. The encoded protein is a receptor on antigen-presenting cells of the immune system and is essential for mediating a broad variety of immune and inflammatory responses including T cell-dependent immunoglobulin class switching, memory B cell development, and germinal center formation. AT-hook transcription factor AKNA is reported to coordinately regulate the expression of this receptor and its ligand, which may be important for homotypic cell interactions. Adaptor protein TNFR2 interacts with this receptor and serves as a mediator of the signal transduction. The interaction of this receptor and its ligand is found to be necessary for amyloid-beta-induced microglial activation, and thus is thought to be an early event in Alzheimer disease pathogenesis. Mutations affecting this gene are the cause of autosomal recessive hyper-IgM immunodeficiency type 3 (HIGM3). Multiple alternatively spliced transcript variants of this gene encoding distinct isoforms have been reported.

Bio-activity
Measured by its binding ability in a functional ELISA. When Recombinant Mouse CD40/TNFRSF5 Fc Chimera is immobilized at 1 μg/mL (100 μL/well), the concentration of Recombinant Mouse CD40 Ligand/TNFSF5 that produces 50% optimal binding is found to be 100-600 ng/mL.
Endotoxin
<0.10 EU/μg of the protein by the LAL method.
Purity
>90%, by SDS-PAGE visualized with Silver Staining and quantitative densitometry by Coomassie Blue Staining.
Notes
Disulfide-linked homodimer
