CF(Carrier-Free)とは?
R&D Systems社組換え体タンパク質製品では通常ウシ血清アルブミン(BSA)をキャリアタンパク質として加えています。キャリアタンパク質を加えることで組換え体タンパク質の安定性が高まり、使用期限が長くなります。また、より濃度の低い溶液での保管も可能となります。CF製品はBSAが含まれない製品となります。一般的に細胞培養や、ELISAのスタンダードにはBSA含有製品を推奨しています。CF製品はBSAが影響してしまうアプリケーションに推奨されます。

Product Details
- Source
- Chinese Hamster Ovary cell line, CHO-derivedAla279-Ser390
- Accession #
- P01137
- Purity
- >97%, by SDS-PAGE visualized with Silver Staining and quantitative densitometry by Coomassie® Blue Staining.
- Predicted Molecular Mass
- 12.8 kDa (monomer)
- SDS-PAGE
- 12 kDa, reducing conditions24 kDa, non-reducing conditions
- Activity
- Measured by its ability to inhibit the IL-4-dependent proliferation of HT‑2 mouse T cells. Tsang, M. et al. (1995) Cytokine 7:389. The ED50 for this effect is 0.04-0.2 ng/mL.The specific activity of Recombinant Human TGF-beta 1 is approximately 2.5 x 104 U/μg, which is calibrated against human TGF‑ beta 1 Standard (NIBSC code: 89/514).
- Bioactivity
- Recombinant Human TGF-beta 1 (Catalog # 240-B) inhibits Recombinant Mouse IL‑4 (Catalog # 404-ML) induced proliferation in the HT-2 mouse T cell line. The ED50 for this effect is 0.04-0.2 ng/mL.
- SDS-PAGE
- 1 μg/lane of Recombinant Human TGF-beta 1 was resolved with SDS-PAGE under reducing (R) and non-reducing (NR) conditions and visualized by silver staining, showing single bands at 12 kDa and 24 kDa, respectively.
- Bioactivity
- Epithelial to Mesenchymal Transition (EMT) was induced in the A549 human lung carcinoma cell line with cell culture media supplemented with Recombinant Human (rh) TGF-beta 1 (Catalog # 240-B). Control cells were cultured without rhTGF-beta 1. EMT induction was confirmed at 48 h by flow cytometric staining for E-Cadherin (filled; Catalog # FAB18381P), an epithelial cell marker, or an isotype control (Catalog # IC0041P). TGF-beta 1 decreased the expression of E-Cadherin.

- Background
- TGF-beta 1
- TGF-beta 1 (transforming growth factor beta 1) is one of three closely related mammalian members of the large TGF-beta superfamily that share a characteristic cystine knot structure (1‑7). TGF-beta 1, -2 and -3 are highly pleiotropic cytokines that are 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 1, mice with targeted deletion show defects in hematopoiesis and endothelial differentiation, and die of overwhelming inflammation (2). Human TGF‑ beta 1 cDNA encodes a 390 amino acid (aa) precursor that contains a 29 aa signal peptide and a 361 aa proprotein (8). A furin‑like convertase processes the proprotein to generate an N‑terminal 249 aa latency‑associated peptide (LAP) and a C‑terminal 112 aa mature TGF‑ beta 1 (8, 9). Disulfide‑linked homodimers of LAP and TGF‑ beta 1 remain non‑covalently associated after secretion, forming the small latent TGF‑ beta 1 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 human TGF‑ beta 1 shares 100% aa identity with pig, dog and cow TGF‑ beta 1, and 99% aa identity with mouse, rat and horse TGF‑ beta 1. It demonstrates cross‑species activity (1). TGF‑ beta 1 signaling begins with high‑affinity binding to a type II ser/thr kinase receptor termed TGF‑ beta RII. This receptor then phosphorylates and activates a second ser/thr kinase receptor, TGF‑ beta RI (also called activin receptor‑like kinase (ALK) ‑5), or alternatively, ALK‑1. This complex phosphorylates and activates Smad proteins that regulate transcription (3, 11, 12). Contributions of the accessory receptors betaglycan (also known as TGF‑ beta RIII) and endoglin, or use of Smad‑independent signaling pathways, allow for disparate actions observed in response to TGF‑ beta in different contexts (11).
