本品为来源于母乳的高纯度酪蛋白酸钠,是纯度高、活性稳定的试剂级功能性蛋白产品。酪蛋白作为哺乳动物乳汁中含量最高的特异性蛋白,是人乳核心营养与功能组分,天然人乳酪蛋白经钠盐改性后,水溶性、分散性及生物适配性大幅提升,可稳定保持天然蛋白的空间构象与生物活性。
相较于常规牛乳源酪蛋白酸钠,母乳源酪蛋白酸钠在氨基酸序列、空间结构、磷酸化修饰位点及杂质组分上高度贴合人体原生蛋白特征,无异种蛋白特异性杂质,生物相容性极佳,可最大程度规避异种乳蛋白带来的实验干扰与生物排斥问题,可为生命科学基础研究、哺乳动物细胞培养、婴幼儿营养机理研究、生物活性制剂开发、肠道微生态研究等诸多领域,提供更贴合人体原生生理状态、数据重复性更高的优质实验原料与科研载体。
The product is high-purity sodium caseinate derived from human milk, a reagent-grade functional protein with high purity and stable activity. As the most abundant specific protein in mammalian milk, casein serves as a core nutritional and functional component of human milk. After sodium salt modification, native human milk casein exhibits greatly improved water solubility, dispersibility and biocompatibility, while stably retaining the native protein conformation and biological activity.
Compared with conventional bovine milk-derived sodium caseinate, human milk-derived sodium caseinate closely matches the characteristics of native human protein in amino acid sequence, spatial structure, phosphorylation modification sites and impurity profiles. It contains no specific heterologous protein impurities and has excellent biocompatibility. It can minimize experimental interference and biological rejection caused by heterologous milk proteins, and provide high-quality experimental materials and research carriers that better mimic the native human physiological state with superior data reproducibility for numerous fields including basic life science research, mammalian cell culture, infant nutrition mechanism research, bioactive formulation development, and gut microbiome studies.
