Anti-Mouse CD40 (FGK45) ColorWheel^® Dye-Ready mAb

ColorWheel^® technology is a novel and proprietary method of creating your own antibody and dye combinations for use in flow cytometry. By incubating any ColorWheel^® antibody with any ColorWheel^® dye, researchers can quickly and simply produce primary conjugated antibodies for use in single color or multicolor flow cytometry analysis. Each ColorWheel^® antibody and dye is lyophilized for long-term storage, allowing for simplicity and flexibility without compromise. ColorWheel^® technology requires both ColorWheel^® antibody and ColorWheel^® dye for Flow Cytometry application.

Tumor necrosis factor receptor superfamily member 5 (UniProt: P27512; also known as B-cell surface antigen CD40, Bp50, CD40L receptor, CD40) is encoded by the Cd40 (also known as Tnfrsf5) gene (Gene ID: 21939) in murine species. CD40 is a single-pass type I transmembrane glycoprotein that is synthesized with a signal peptide (aa 1-19), which is subsequently cleaved off to produce the mature form that contains an extracellular domain (aa 20-193), a transmembrane domain (aa 194-205), and a cytoplasmic domain (aa 216-289). CD40 serves as a receptor for TNFSF5/CD40L. It is a costimulatory protein found on antigen-presenting cells and is required for their activation. Its expression has been observed in B cells, basal epithelial cells, macrophages, follicular dendritic cells, endothelial cells, and a subset of CD34+ hematopoietic progenitors. It transduces TRAF-6 and MAP3K8-mediated signals that activate ERK in macrophages and B cells that leads to induction of immunoglobulin secretion. CD40 pathway is essential for the survival of many cell types including germinal center B cells, dendritic cells, and endothelial cells under normal and inflammatory conditions. Five isoforms of CD40 have been described that are produced by alternative splicing. (Ref.: Eliopoulos, AG., et al. (2003). EMBO J. 22(15); 3855-3864).

Clone FGK45 is a rat monoclonal antibody that detects murine CD40. It targets an epitope within the extracellular domain.

Lyophilized from PBS containing D-Mannitol and Sucrose, normal appearance is a dried pellet. Reconstituted antibody solution is stable and functional as assessed by functional testing. Contains no biocide or preservatives, such as azide.

1.0 mg/mL after reconstitution at 25 μL in PBS. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Recommend storage of lyophilized product at 2-8°C. Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial. Reconstitute each vial by adding 25 μL PBS. Protect from light.
