产品介绍

产品介绍

? ? ? ? 人血清白蛋白(Human Serum Albumin,HSA)作为人血浆中含量最丰富的蛋白,是激素、脂类等物质的转运载体,其主要生理功能是调节血浆pH值和维持血浆渗透压。

? ? ? ? OsrHSA(Recombinant Human Serum Albumin from Oryza sativa)是利用水稻胚乳细胞表达平台(OryzHiExp)和纯化平台(OryzPur)研发的重组人血清白蛋白,不含有动物源成分,可杜绝血液源的病毒感染风险。与胎牛血清(FBS)、血浆来源白蛋白(pHSA)和牛血清白蛋白(BSA)相比,OsrHSA具有更高的纯度,更好的批次稳定性,可以用于各类研究,包括生物制药、细胞治疗、基因治疗的细胞培养等,可替换血清,促进细胞生长。同时,OsrHSA也被广泛用于生物医药生产中作为药物载体,疫苗保护剂、细胞冻存保护剂和医疗器械包埋剂等。


应用领域

生物制药、人用疫苗、细胞培养、医疗器械、体外诊断、美容等。


注意事项

复溶:建议用PBS重溶OsrHSA冻干粉。溶解后的无菌OsrHSA在4℃可保存3-6个月。

开启后,请尽快使用,避免污染。

Product Introduction

As the most abundant protein in human plasma, human serum albumin (HSA) is the transporter of hormones, lipids and other substances. Its main physiological function is to regulate plasma pH and maintain plasma osmotic pressure.

Osrhsa (recombinant human serum albumin from Oryza sativa) is a recombinant human serum albumin developed by using rice endosperm cell expression platform (oryzhiexp) and purification platform (oryzpur). It does not contain animal derived ingredients and can eliminate the risk of blood derived virus infection. Compared with fetal bovine serum (FBS), plasma derived albumin (pHSA) and bovine serum albumin (BSA), osrhsa has higher purity and better batch stability. It can be used in various research fields, including biopharmaceutical, cell therapy and cell culture of gene therapy. It can replace serum and promote cell growth. At the same time, osrhsa is also widely used in biomedical production as drug carrier, vaccine protector, cell cryoprotectant and medical device embedding agent.


Application

Biopharmaceuticals, human vaccines, cell culture, medical devices, in vitro diagnosis, beauty, etc.


Matters needing attention

Re dissolving: it is suggested to re dissolve osrhsa lyophilized powder with PBS. The dissolved sterile osrhsa can be stored at 4 ℃ for 3-6 months.

After opening, please use it as soon as possible to avoid pollution.
