Albumin, being the most abundant plasma protein in humans, is recognized by the body as a 'self' component，without substantial toxicity or immunogenic response. OsrHSA is a recombinant human serum albumin produced via Healthgen’s patented rice-endosperm expression platform(OryzHiExp). Coated with OsrHSA, the medical device surface creates a biocompatible biological interface that minimizes direct interaction between the device's non-native surface and the patient's tissues, thus significantly enhancing overall device safety.
