Product Datasheets

Carrier Free

What does CF mean?

CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.

What formulation is right for me?

In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Background: CD40/TNFRSF5

CD40, also known as TNFRSF5, is a type I transmembrane glycoprotein member of the TNF receptor superfamily (1). Mature Cynomolgus Monkey CD40 consists of an extracellular domain, a transmembrane domain, and a cytoplasmic domain (2). The extracellular domain (21-193 aa) of Cynomolgus Monkey CD40 shares 96%, 58% and 56% amino acid (aa) sequence identity with human, mouse and rat CD40, respectively. CD40 is expressed on the surface of B cells, dendritic cells, macrophages, monocytes and platelets, as well as endothelial and epithelial cells (4, 5). 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 the aggregation of CD40 molecules resulting in the initiation of bidirectional intracellular signaling in both CD40 and CD40L expressing cells (6). CD40 ligation by CD40L promotes B cell activation and T cell‑dependent humoral responses (7, 8). CD40 serves multiple functions in both hematopoietic and epithelial cancers and is a target for tumor immunotherapy (9, 10). Dysregulation of CD40/CD40L expression and interactions contributes to the immune deficiency associated with HIV infection and AIDS (11, 12). It is also implicated in the pathology of multiple cardiovascular diseases including atherosclerosis, atherothrombosis, and restenosis (13, 14).
