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.

Storage and Handling:
Stored at temperatures 2-8℃ for 24 months (HYC002C01, HYC001C01). 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.
1. HPLC analysis
OsrHSA was analyzed by size exclusion chromatography HPLC (SEC HPLC), showing the purity is more than 99.99%.
2. OsrHSA has equal safety in Vivo to pHSA
The titers of individual immunoglobulins IgG, IgM, IgE, and IgA showed no significant difference among the pHSA, OsrHSA, and saline groups, and the titers of C4 complement were not significantly different.
3. Performance of OsrHSA in CIK cell therapy
OsrHSA was used in PBMC culture to induce the CIK cells. After 14 days, the total cell amount reach to 6.6X109, and
the CD3+CD56+ rate is more than 22.97%. It showed that OsrHSA has effective action in promoting CIK cell growth.
