Description

Human Serum Albumin (HSA) is the most abundant protein in human plasma. It functions as a carrier protein for various substances such as steroids, fatty acids, and thyroid hormones, and plays a critical role in regulating plasma pH and maintaining osmotic pressure.

This product is recombinant human serum albumin (rHSA) derived from rice endosperm cells. Compared with animal-derived bovine serum albumin (BSA) or plasma-derived human serum albumin (pHSA), it contains no animal components, thereby eliminating the risk of interference from animal-derived IgG, hormones, and potential animal-borne viruses.

Advantages

• Animal-Free Origin: Produced through recombinant technology with no risk of exogenous viral contamination. No animal-derived materials are used at any stage of the manufacturing process.
• Consistent Quality: Manufactured in bulk with strict quality control to ensure batch-to-batch consistency and reliable performance.
• Cell Culture Compatibility: Eliminates interference from animal-derived viruses, offering a well-defined and stable supplement for cell culture media.
• Lyophilized Form: Easy to store and transport due to its freeze-dried format.

Applications 

As a non-animal-derived protein, recombinant HSA is widely used as a substitute for bovine serum albumin (BSA). It can partially replace serum in cell culture to promote cell growth, serve as a component in enzyme reaction buffers to prevent enzyme adsorption to tube walls, and stabilize certain proteins during incubation.

It is also suitable for various immunoassays, protein quantification and detection, and for stabilizing enzymes, antigens, and antibodies in research applications.
