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 2

TGF-beta 2 (transforming growth factor beta 2) is one of three closely related mammalian members of the large TGF-beta  superfamily that share a characteristic cysteine knot structure (1‑7). TGF-beta 1, -2 and -3 are highly pleiotropic cytokines proposed to act as cellular switches that regulate processes such as immune function, proliferation and epithelial-mesenchymal transition (1-4). Each TGF-beta isoform has some non-redundant functions; for TGF-beta 2, mice with targeted deletion show defects in development of cardiac, lung, craniofacial, limb, eye, ear and urogenital systems (2). Mouse TGF-beta 2 cDNA encodes a 414 amino acid (aa) precursor that contains a 19 aa signal peptide and a 395 aa proprotein (8). A furin-like convertase processes the proprotein to generate an N-terminal 283 aa latency-associated peptide (LAP) and a C-terminal 112 aa mature TGF-  beta 2 (8, 9). Disulfide-linked homodimers of LAP and TGF-beta 2 remain non-covalently associated after secretion, forming the small latent TGF-beta 2 complex (8-10). Covalent linkage of LAP to one of three latent TGF-beta binding proteins (LTBPs) creates a large latent complex that may interact with the extracellular matrix (9, 10). TGF-beta is activated from latency by pathways that include actions of the protease plasmin, matrix metalloproteases, thrombospondin 1 and a subset of integrins (10). Mature mouse TGF-beta 2 shares 100% aa identity with rat TGF-beta 2, and 97% aa identity with human, porcine, canine, equine and bovine
TGF‑ beta 2. It demonstrates cross-species activity (1). In most cells, TGF-beta 2 signaling begins with binding to a complex of the accessory receptor betaglycan (also known as TGF-beta  RIII) and a type II ser/thr kinase receptor termed TGF-beta  RII, which then phosphorylates and activates another ser/thr kinase receptor, TGF-beta  RI (also called activin receptor-like kinase (ALK) -5), or alternatively, ALK-1. The whole complex phosphorylates and activates Smad proteins that regulate transcription (3, 11, 12). In bone -related cells, however, TGF-beta 2 also signals through TGF-beta RIIB (a splice variant of TGF-beta RII), independently of TGF-beta  RIII (13). Use of other signaling pathways that are Smad-independent allows for disparate actions observed in response to TGF-beta in different contexts (11).

Recombinant Mouse TGF-beta 2 Protein
By Anonymous on 03/28/2019
Application: used in direct ELISA to check the specificity of Abcam's TGFb3 antibody

I coated my plates with 50ng/well of recombinant mouse TGFb1 & 2 proteins and in-house produced human TGF beta 3. I wanted to check the specificity of Abcam's TGF beta 3 antibody. I did not use it because it showed cross reactivity with TGF beta 2
