Formulation, Preparation and Storage

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.

Carrier: 241-R2

Background: TGF-beta RII

Most cell types express three sizes of receptors for TGF-beta. These are designated type I (53 kDa), type II (70-85 kDa), and type III (250-350 kDa). The type III receptor, a proteoglycan that exists in membrane-bound and soluble forms, binds TGF-beta 1, TGF-beta 2, and TGF-beta 3 but does not appear to be involved in signal transduction. The type II receptor is a membrane-bound serine/threonine kinase that binds TGF-beta 1 and TGF-beta 3 with high affinity and TGF-beta 2 with a much lower affinity. The type I receptor is also a membrane-bound serine/threonine kinase that apparently requires the presence of the type II receptor to bind TGF-beta. Current evidence suggests that signal transduction requires the cytoplasmic domains of both the type I and type II receptors.

The recombinant soluble TGF-beta type II receptor is capable of binding TGF-beta 1, TGF-beta 3, and TGF-beta 5 with sufficient affinity to act as an inhibitor of these isoforms at high concentrations. The soluble receptor also binds TGF-beta 2, but with an affinity at least two orders of magnitude lower. Binding of TGF-beta 1, TGF-beta 3, and TGF-beta 5 to the soluble TGF-beta type II receptor can also be demonstrated by using the soluble receptor as a capture agent on ELISA plates and this observation has been used as the basis for the development of immunoassays for these isoforms of TGF-beta.

FAQs for Recombinant Human TGF-beta RII Protein

Showing  1 - 1 of 1 FAQ Showing All
  • Q: Can Recombinant Human TGF-β RII (Catalog # 241-R2) be used as a capture reagent in an ELISA-like assay?

    A: Yes, it can, but Recombinant Human TGF-β RII Fc Chimera (Catalog # 341-BR) binds to the plate better and has a higher affinity for the ligand. Therefore, Catalog # 341-BR is recommended to use as a capture reagent in ELISA applications.
