Product Description

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.
