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: 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, and appears to participate in both TGF-beta dependent and independent cellular signaling. The Type II receptor, by contrast, 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 requires the presence of the Type II receptor to bind TGF-beta. Evidence suggests that signal transduction requires the cytoplasmic domains of both the Type I and Type II receptors. TGF-beta receptor II isoform 2 (also TGF-beta RII isoform A) is an alternatively spliced variant of the standard Type II TGF-beta receptor (or TGF-beta RII isoform 1) that possesses a 27 amino acid substitution for Val10 near the N-terminus of the mature protein. Both T beta RII and T beta RII isoform 2 bind TGF-beta 1 and TGF-beta 3 with high affinity. However, only TGF-beta RII isoform 2 also binds TGF-beta 2 with high affinity in the absence of TGF‑ beta  RIII. While TGF-beta RII is widely expressed on cells, TGF-beta RII isoform 2 shows distinct expression pattern mainly associated with bone‑related cells, such as osteoblasts and mesenchymal precursor cells. TGF-beta RII isoform 2 may play an important role in TGF-beta 2 binding and signaling in cells lacking TGF-beta RIII.
