Bulk anti-CD40 In Vivo Antibody – Low Endotoxin (FGK4.5)
ichorbio’s anti-CD40 In Vivo Antibody – Low Endotoxin (FGK4.5) is manufactured in a cGMP compliant, ISO Quality Standard 9001:2015 facility. ichorbio’s low endotoxin antibodies have half the endotoxin of comparable antibodies from our competitors at less than 1.0 EU/mg. If ichorbio’s low endotoxin antibodies are not low enough we also offer ultra low endotoxin antibodies which have even less endotoxin (<0.75EU/mg) at an even higher purity (98% versus 95%). ichorbio offers Amazon vouchers or donations to the NC3Rs for reviews of this product: click here for more information. ichorbio: the best antibodies for in vivo research.
Anti-CD40 In Vivo Antibody – Low Endotoxin (FGK4.5) recognizes an epitope on Mouse CD40
This monoclonal antibody was purified using multi-step affinity chromatography methods such as Protein A or G depending on the species and isotype.
B cells, basal epithelial cells, macrophages, follicular dendritic cells, and endothelial cells
CD40, also known as TNFSF5, is a type I transmembrane protein and member of the TNF receptor family. The binding of CD40L (CD154) on TH cells to CD40 activates antigen presenting cells and induces a variety of downstream effects. CD40 is expressed on B cells, dendritic cells, monocytes, thymic epithelial cells and, at low levels, on T cells. Signaling though CD40 plays an important role in the proliferation and differentiation of B cells and is critical for immunoglobulin (Ig) class switching. The membrane-anchored CD40L is expressed almost exclusively on activated CD4+ T lymphocytes. Failure to express CD40L leads to “immunodeficiency with hyper-IgM”, a disease characterized by failure to produce IgG, IgA and IgE. Some of the early intracellular signaling by the CD4-CD40L system includes the association of the CD40 with TRAFs and the activation of various kinases (4). Adaptor protein TNFR2 interacts with this receptor and serves as a mediator of the signal transduction. The interaction of CD4-CD40L is found to be necessary for amyloid-beta-induced microglial activation, and thus is thought to be an early event in Alzheimer disease pathogenesis.
