Recombinant HSA With White To Light Beige Lyophilized Powder HSA High Purity

Recombinant Serum Albumin HSA with White to Light Beige Lyophilized Powder has high purity

Description

Healthgen Biotech recombinant human serum albumin (OsrHSA) has excellent batch consistency. Using self-pollination rice as the bioreactor to express the OsrHSA, with the world's advanced facility and top production proceeding to extract and purify the OsrHSA, Healthgen Biotech can ensure the excellent consistency of OsrHSA from different batches. OsrHSA is animal origin free, which effectively avoid any potential risk of animal contaminants, bacteria, prions, virus and contagious protein disease.

Wuhan Healthgen Biotechnology Corp. has been committed in research of protein purification, meanwhile our technology has been patented by the US Patent and Trademark Office on May 15th 2015 and been granted the patent of "A method for isolating and purifying recombinant human serum albumin from transgenic rice grain", which patent number is US9, 023,990. Now, our OsrHSA purity can be higher than 99%.

Introduction:

Human serum albumin is the most abundant protein in human plasma. It can transport hormones, lipids and other molecules and maintain osmotic pressure. OsrHSA is a recombinant human serum albumin derived from rice grains, which provides an excellent solution for animal free medium. Compared to FBS, pHSA and BSA, OsrHSA has higher purity and excellent batch consistency. Meanwhile, OsrHSA is widely used as excipient, stabilizer and embedding agent in bio-pharmaceutical applications.

Physical Appearance: Off-white to light beige lyophilized powder

Formulation: It is lyophilized without stabilizer or surface active agent

Purity: More than 99% as determined by SDS-PAGE and HPLC analysis.

Endotoxin: Less than 0.01EU/mg

Applications:

Vaccine manufacture and formulation

In vivo/vitro diagnostics

Cryopreservation of cell

Coating of medical devices

Storage and Handling: Stored at temperatures 2-8℃ for 48 months. For lyophilized powder, it is recommended to reconstitute the lyophilized OsrHSA in sterile PBS. Upon reconstitution OsrHSA should be stored below -20℃. Use as soon as possible after opening. Please avoid freeze-thaw cycles.

Supplemental Description

Human serum albumin has been widely used as plasma expansion reagent. Because of its non-enzymatic activity and no immunogenicity, etc. HSA can also be used as excipient and stabilizer in a variety of pharmaceutical preparations. In addition, HSA is also used as a drug carrier due to its antioxidant properties, thereby conferring drugs better physicochemical properties. At present, most HSA products in the market are directly derived from human plasma.

On the one hand, due to the potential existence of various infectious disease pathogens in the human blood, especially AIDS, hepatitis B and other viruses. Thereby, these virus from human plasma will be brought with HSA to the final products. rHSA produced by plant derived recombinant proteins technology can effectively avoid the risks of virus pollution and infection. What’s more, the supply of human blood is limited. Therefore, it’s very urgent to search blood substitutes. The establishment and development of recombinant technology provide an important method for the acquisition of biological materials. In recent years, many researchers have been hotly committed to the recombinant human serum albumin research.
