纯度
≥ 95% as determined by reducing SDS-PAGE.
内毒素
< 1 EU/µg as determined by LAL test.
制剂
Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH 7.4.
描述
Recombinant Human PSG1 Protein is produced by Mammalian Cells system. The target protein is expressed with sequence (Gln35-Pro419) of Human PSG1(Accession # P11464) fused with His tag at the C-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.
（1）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；
（2）干粉蛋白复溶浓度建议在0.1-0.5 mg/mL，不能低于0.1mg/mL，长期储存请添加保护剂（如0.1%BSA），并分装保存，避免反复冻融；
（3）液体蛋白的保存温度及效期请参考说明书，如对液体蛋白浓度有要求，请提前咨询销售或者技术支持。
复溶
Always centrifuge tubes before opening.Do not mix by vortex or pipetting.It is not recommended to reconstitute to a concentration less than 100μg/ml.Dissolve the lyophilized protein in distilled water.Please aliquot the reconstituted solution to minimize freeze-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。
请在蛋白复溶计算器中输入蛋白总质量和所需终浓度，快速计算您需要添加溶液的体积吧！
PSG1, also named CD66 antigen-like family member F, Fetal liver non-specific cross-reactive antigen 1/2, PSG95, Pregnancy-specific beta-1 glycoprotein C/D, is a secreted protein which belongs to the immunoglobulin superfamily, CEA family. It contains 3 Ig-like C2-type (immunoglobulin-like) domains and 1 Ig-like V-type (immunoglobulin-like) domain. The human placenta is a multihormonal endocrine organ that produces hormones, enzymes, and other molecules that support fetal survival and development.
