Background
CD40 is a type I transmembrane glycoprotein belonging to the TNF receptor superfamily. The mature hCD40 consists of a 172 amino acid (aa) extracellular domain, a 22 aa transmembrane region and a 62 aa cytoplasmic domain (1). Human and mouse CD40 share 62% aa identity. CD40 is expressed in B cells, follicular dendritic cells, dendritic cells, activated monocytes, macrophages, endothelial cells, vascular smooth muscle cells, and several tumor cell lines (2). The extracellular domain has the cysteine-rich repeat regions, which are characteristic for many of the receptors of the TNF superfamily. Interaction of CD40 with its ligand, CD40L, leads to aggregation of CD40 molecules, which in turn interact with cytoplasmic components to initiate signaling pathways. Early studies on the CD40-CD40L system revealed its role in humoral immunity. Interaction between CD40L on T cells and CD40 on B cells stimulated B cell proliferation and provided the signal for immunoglobulin isotype switching (3). Mutations in the CD40L gene, which resulted in a CD40L molecule unable to interact with CD40, are responsible for the hyper-IgM syndrome (4). Cross-linking of CD40 with antibodies or by CD40 binding to CD40L produces cell type-specific responses which include costimulation and induction of proliferation, induction of cytokine production, rescue from apoptosis, and upregulation of adhesion molecules (5). Some of the early events of intracellular signaling by the
CD40‑CD40L system include the association of the CD40 with TRAFs and the activation of various kinases (6‑8).

I wanna know does CD40 antibody for IHC-P comes with positive control slide?
- Our CD40 antibodies do not come with positive control slides however you can use any type of primary carcinoma cell as a positive control. I recommend breast carcinoma as this is what we have tested our CD40 antibodies on.
-
We are studying CD40L in our system. It has been known that both CD40 and CD11b are receptors for CD40L. We need CD40 antibody to neutralize CD40 binding to CD40L, then we may prove what is function for CD11b binding to CD40L. Do you have any CD40 Ab which has block function only between CD40 and CD40L, but not between CD11b and CD40L?
- Unfortunately, none of our CD40 antibodies have been specifically tested for this application.
