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: IL-10

Interleukin-10 (IL-10) is a pleiotropic cytokine that plays a crucial role in regulating immune and inflammstory responses (1). It has closely related homologs in the genome of several viruses including the human cytomegalovirus (HCMV), a prevalent pathogen that can remain in humans as a latent infection (2). Viruses use multiple strategies to avoid detection and clearance by the host immune system. One of these strategies is to express virus-encoded host cytokine homologs, such as IL-10, to modulate the host immune system to the virus’ advantage. HCMV IL-10 is encoded from noncontiguous stretches in the viral genome and is transcribed early during infection. It shares 27% amino acid sequence identity with the endogenous human IL-10. Despite its low homology with the human protein, it can bind to the human IL-10 receptor complex and induces signal transduction. HCMV IL-10 has been shown to suppress cytokine production and inhibit proliferation of mitogen‑stimulated human peripheral blood mononuclear cells. HCMV IL-10 can also down regulate the antigen-presenting and accessory cell functions of human monocytes. These immunosuppressive properties of HCMV IL-10 likely contribute to immune evasion during virus infection (3).
