描述
Recombinant Human Angiopoietin-like 7/ANGPTL7 Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Gln27-Pro346) of human Angiopoietin-like 7 (Accession #NP_066969.1) fused with a 6×His tag at the C-terminus.
内毒素
< 0.1 EU/μg of the protein by LAL method.
生物活性
Measured by its binding ability in a functional ELISA. Immobilized Recombinant Human ANGPTL7 at 5 μg/mL (100 μL/well) can bind Recombinant Human LILRB4 with a linear range of 0.5-3.5 μg/mL.
制剂
Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.Contact us for customized product form or formulation.
储存
Store the lyophilized protein at -20°C to -80 °C for long term.
After reconstitution, the protein solution is stable at -20 °C for 3 months, at 2-8 °C 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 vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid votex 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。
研究方向
人类 ANGPTL7/血管生成素相关 7 蛋白是 Angptl 家族中研究最少的成员。它最初是从人角膜细胞中克隆出来的，被命名为角膜衍生转录物6。血管生成素相关蛋白7可以修饰人黑色素瘤细胞和小梁网细胞中细胞外基质蛋白的表达，表明它具有角膜形态发生素的功能，并且可以调节眼内压。
背景信息
Angiopoietin-like 7 (ANGPTL7), also known as Corneal-Derived Transcript 6 (CDT6), is a secreted glycoprotein that is structurally related to the angiopoietins. ANGPTL7 is expressed in the corneal stroma, trabecular meshwork, and sclera and is elevated in glaucoma aqueous humor. Its production is up regulated in trabecular meshwork cells by glucocorticoids and TGF-beta and in cartilage by TNF-alpha. Overexpression of ANGPTL7 in trabecular meshwork cells inhibits the production of collagen and proteoglycans . When overexpressed in tumor cells it promotes collagen and proteoglycan deposition but inhibits tumor xenograft progression and tumor angiogenesis.
