Lysozyme (LYZ) is a small protein with 14.7 kDa molecular weight, contains 130 amino acid. Lysozyme is a potent antimicrobial enzyme, by catalytic hydrolysis of their cell wall peptidoglycan, which contains sugars and amino acids. The sugar component consists of A-(1, 4)-linked N-acetylglucosamine and N-acetylmuramic acid and this bond is broken by lysozyme. This compromises the bacterial cell wall and causes the bacterium to burst under the high internal osmotic pressure. The recombinant human lysozyme (OsrhLYZ) was expressed in the patented rice endosperm, has been demonstrated that has the same physical and chemical with the native lysozyme.

DMF(No.29648)
| Items | OsrHSA (rice-derived) | ScrHSA (yeast-derived) |
| Safety | Free of animal, Virus, Pathogene, low endotoxin | Possible residual yeast cell wall components (such as B-glucan),additional removal of endotoxins required |
| Post-translational modifications | No glycosylation modification, structure identical to native HSA | Glycosylation modification, Risk of inclusion formation requires reproducibility |
| Production process | Simple process with Three-step chromatography purification | High-density fermentation is costly, with more complex production process |
| Scale up | Low-cost in rice cultivation Long-term stable storage in rice seeds Single-batch purification cycle: 24h Low immunogenicity, suitable for stem/primary cells, high batch consistency |
High capital investment for fermentation equipmentSingle-batch production cycle:3-7 days Residual host proteins affect cell growth, batch difference exists |
| Cell culture compatibility | ||
| Regulation and ethics | Comply with regulations and shorten the filing time, environmentally fri endly and sustainable |
Microbial fermentation requires strict GMP control, Acceptance of genetically modified yeast varies by region |

Yes, we do. From our comparative test, OsrHSA is structurelly and biochemically equivalent to pHSA, and functions equivalently to pHSA in terms of binding capacity and promotion of cell growth. In addition, OsrHSA displays the same immunogenicity as pHSA.
