人血清白蛋白（HSA）由肝实质细胞合成，是人血浆中含量最高的蛋白，可作为载体运输脂肪酸、氨基酸 等营养物质，同时能够调节血浆 pH 和维持血浆渗透压，是动物细胞培养基中的重要组分之一。 NebuSelect™ Recombinant Human Serum Albumin是利用基因重组技术从毕赤酵母中表达纯化得到的， 不含有动物源成分，无任何血源性病毒感染风险，批稳定性高。

Human serum albumin (HSA) is synthesized by liver parenchymal cells and is the most abundant protein in human plasma. It can serve as a carrier to transport nutrients such as fatty acids and amino acids, while also regulating plasma pH and maintaining plasma osmotic pressure. It is an important component in animal cell culture media. NebuSelect™ Recombinant Human Serum Albumin is expressed and purified from Pichia pastoris using genetic recombination technology, and does not contain animal-derived components, posing no risk of blood-borne virus infection. It exhibits high batch stability. NBL-240221 is a lipid-enriched albumin that utilizes recombinant human serum albumin as a lipid carrier, enhancing its solubility. It is safe and non-toxic, and can be used for various types of cell culture.
