活性重组蛋白 Recombinant Human Latent TGF beta 2 / LAP / Cetermin / TGFB2 Protein-武汉瑾萱生物科技有限公司商城首页

研究方向

作为 TGF-β-2 信号通路的核心参与者，TGF-β2/TGFB2 蛋白承担潜伏相关肽 (LAP) 和转化生长因子 β-2 (TGF-β- 2）链条。这些链共同分别形成 TGF-β-2 的调节亚基和活性亚基。值得注意的是，TGF-β2/TGFB2 对于在细胞外基质内储存期间维持 TGF-β-2 链处于潜在状态至关重要。该蛋白与 TGF-β-2 进行非共价结合，通过与“环境分子”（包括 LTBP1 和 LRRC32/GARP）相互作用来复杂地调节其激活。这些相互作用在控制 TGF-β-2 的激活中发挥着关键作用，有助于这一关键信号通路的精细调节。

描述

Recombinant Human Latent TGF-beta 2 Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Leu21-Ser414) of Human Latent TGF-beta 2 (Accession #NP_003229.1) fused with with His tag at the N-terminus.

储存

Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt.
After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.未开盖的干粉蛋白在 -20°C至-80°C可保存12个月；
复溶之后，蛋白溶液在-20°C及以下可保存3个月，在2-8℃可保存1周。

复溶

Centrifuge the tube before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.收到重组蛋白产品之后请检查蛋白冻干粉末是否贴于瓶底，如果粉末浮起，开盖之前请先低温离心。将蛋白用说明书中指定的缓冲液复溶至0.1-0.5 mg/mL（请注意蛋白复溶浓度不能低于0.1 mg/mL），室温平衡5-10 min保证充分溶解，复溶过程中请不要剧烈涡旋及吹打蛋白溶液。如需长期储存，建议复溶时添加载体蛋白或者稳定剂（如0.1% BSA, 5% HSA, 10% FBS 或者 5% 海藻糖），同时将复溶后的蛋白溶液按照需求进行分装，储存于-20°C至-80°C，随取随用，避免反复冻融。

背景信息

This protein belongs a member of the transforming growth factor beta (TGFB) family of cytokines, which are multifunctional peptides that regulate proliferation, differentiation, adhesion, migration, and other functions in many cell types by transducing their signal through combinations of transmembrane type I and type II receptors (TGFBR1 and TGFBR2) and their downstream effectors, the SMAD proteins. Disruption of the TGFB/SMAD pathway has been implicated in a variety of human cancers. The encoded protein is secreted and has suppressive effects of interleukin-2 dependent T-cell growth. Translocation t(1;7)(q41;p21) between this gene and HDAC9 is associated with Peters' anomaly, a congenital defect of the anterior chamber of the eye. The knockout mice lacking this gene show perinatal mortality and a wide range of developmental, including cardiac, defects. Alternatively spliced transcript variants encoding different isoforms have been identified.
