Notacow™ rAlbumin (Recombinant Human Serum Albumin)

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. Notacow™ Advantages Animal-Origin-Free Hormone-Free Immunoglobulin-Free Recombinant Fungal Expression High Purity (≥98%) Exceptional Lot-to-Lot Consistency Key Features & Benefits Animal-Origin-Free – Produced without animal-derived materials or plasma components. Hormone-Free – Manufactured without endogenous animal or human hormones that may interfere with sensitive biological assays. Immunoglobulin-Free – Free of immunoglobulins commonly present in serum-derived albumin, reducing background interference and improving assay reproducibility. Recombinant Human Serum Albumin – Structurally and functionally comparable to native human serum albumin. Fungal Expression System – Produced using recombinant fungal cells for scalable, reliable manufacturing. High Purity – Purified to minimize host-cell proteins and process-related impurities. Exceptional Lot-to-Lot Consistency – Recombinant production ensures reproducible performance across manufacturing batches. Enhanced Safety Profile – Eliminates risks associated with plasma-derived contaminants and adventitious agents. Reliable Global Supply – Fermentation-based production removes dependence on plasma collection and animal-derived raw materials.
