生物活性Testing in progress
蛋白构建A DNA sequence encoding the SARS-CoV-2 (2019-nCoV) Spike RBD(V483I)-His Recombinant Protein (YP_009724390.1) (Arg319-Phe541(V483I)) was expressed with a polyhistidine tag at the C-terminus.
NP No.YP_009724390.1
表达宿主HEK293 Cells
种属2019-nCoV
预测 N 端Arg319
分子量The recombinant SARS-CoV-2 (2019-nCoV) Spike RBD(V483I)-His Recombinant Protein consists of 234 amino acids and predicts a molecular mass of 26.6 kDa.
缓冲液Lyophilized from sterile PBS, pH 7.4.
Please contact us for any concerns or special requirements.
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the hard copy of CoA.
运输方式In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
稳定性 & 储存条件Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃
Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
复溶A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

[摘要]以麦麸酶法降解液为原料，采用D201大孔树脂对阿魏酸进行分离提纯，探讨了上柱工艺条件和洗脱条件，确定最佳离子交换操作工艺：室温下，料液阿魏酸浓度在20OOmg／L-3000mg／L之间，pH值9．0，上柱流速1 mE／min，洗脱剂配比(V／V)为无水乙醇：水：盐酸=60：36：4，洗脱流速为1 ml／min。在该操作工艺条件下，阿魏酸收率达97％以上，且纯度大大提高。 阿魏酸(4-羟基-3-甲氧基肉桂酸，FA)是植物中普遍存在的一种酚酸，很少以游离态存在，多与低聚
