Description
Notacow™ rAlbumin is a premium recombinant human serum albumin (rHSA) produced using a proprietary fungal expression platform and manufactured entirely without animal-derived materials. Designed as a high-performance alternative to plasma-derived albumin, Notacow™ rAlbumin delivers the functionality of native human serum albumin while providing exceptional purity, lot-to-lot consistency, and supply reliability.
Unlike plasma-derived albumin, Notacow™ rAlbumin is animal-origin-free, hormone-free, and immunoglobulin-free, eliminating many of the variability and contamination concerns associated with biological source materials.
Its recombinant production process provides a highly reproducible protein ideally suited for sensitive research, diagnostic, and bioprocessing applications.
Whether used as a carrier protein, stabilizer, media supplement, or formulation component, Notacow™ rAlbumin offers dependable performance without relying on human plasma or animal-derived ingredients.
Why Choose Notacow™?
Researchers increasingly require reagents that deliver reproducible results while supporting animal-free workflows. Notacow™ rAlbumin combines the proven functionality of human serum albumin with the advantages of recombinant fungal expression to provide a highly consistent protein free from plasma-derived variability, hormones, and immunoglobulins.
The result is a dependable albumin source for advanced cell culture and next-generation biologics.
