Details
Description:Mouse monoclonal antibody to human Transforming Growth Factor beta (TGF-β)
Purification: Protein G affinity purified
Product Type:Primary antibody
Target Protein:Human TGF-β
Immunogen:TGF-βfrom human platelets
Fusion Myeloma: Sp2/0-Ag14
Specificity:Western blotting demonstrated that this antibody reacts with the dimeric (25kDa) and monomeric (12.5kDa.) forms of TGF-β under both non-reducing and reducing conditions respectively. This antibody recognizes both human platelet-derived and recombinant TGF-β in ELISA.
Species Reactivity: Human, others not tested.
Host / Isotype: Mouse, IgG1 Kappa
Formulation: Lyophilized in 0.01M PBS, pH 7.0.
Reconstitution:Double distilled water is recommended and to adjust the final concentration to 1.00mg/mL.
Storage: Store at -20oC
Research Area:Growth Factors and Their Receptors, Angiogenesis
Background:
Transforming growth factor beta (TGF-β) has three isoforms (TGF-β1, TGF-β2, and TGF-β3) with similar functions.
The cytokine is a homodimer linked by disulfide bind. Inside cells, the cytokine forms a small latent complex with latent associated peptide (LAP). This small complex binds to latent TGF-β binding protein (LTBP) to be secreted to extra-cellular matrix. Disassociation of the latent proteins from TGF-β results in the release of the cytokine to its receptor. The process is called activation, which can be influenced by various factors, including proteases, metalloproteases, extreme pH, mild acidic condition, reactive oxygen species and integrins.
TGF-β is an anti-proliferation factor in normal cells. It increases the synthesis of p15 and p21, which can block the cyclin: CDK complex, and causes cells to stop at G1 phase. The cytokine can induce apoptosis through both SMAD and DAXX pathways. In cancer cells, TGF-β signaling is altered and TGF-β no longer stops cell proliferation.
Applications:
Western Blot:This antibody, when used at concentration of 50-500ng/mL, will allow visualization of 100-500ng/lane of TGF-β.
Neutralizing Activity: This antibody neutralizes TGF-β activity in vitro and in vivo.In an inhibition assay of CCL/64 cell growth and in a NRK-49F colony forming assay, the antibody neutralized TGF-β bioactivities. The effect of micro-injection of this antibody into one blastomere of two cell stage Xenopus embryos indicated that it was also able to neutralize the bioactivity of TGF-βin vivo.
Immunohistochemistry: Can be used in immunohistochemical applications to locate TGF-β within tissues.

目前人们可以获得大量的治疗方法如乳膏和药物来促进头发脱落,但是没有方法非常有效地促进头发生长。已知毛囊干细胞发送信号来指示毛囊和自然头发再生。人们使用一种被称作生物发光的分子成像技术来在细胞水平上展示这些再生过程。生物发生信号是在特异性的化学底物上产生的。这些信号容易被非常灵敏的光学成像系统识别,因而可以观察到在最小的地方(即毛囊干细胞)中正在发生的事情。
韩国庆北大学医学院核医学部门主任和教授Byeong-Cheol Ahn博士说,“利用毛囊干细胞进行头发再生是一种新兴的有望治疗头发脱落的方法。分子成像能够加速这种疗法的开发。这项研究是第一次利用体内分子成像技术来研究毛囊再生。”
当前的研究涉及将毛囊干细胞移植到模式动物中来观察它们是否能够像正常细胞那样生长和增殖。
利用生物发光报告基因的表达产物作用于特定底物发光来非侵入式地追踪毛囊干细胞的治疗过程。目前有来源于萤火虫、甲虫和其他生物发光有机体中的几种生物发光报告基因供人们选择。利用生物发光报告基因进行追踪的策略对干细胞研究是比较理想的,这是因为生物发光只在活细胞中发挥作用。
