Pall 15950-017 Ultroser™ G serum substitute 20mL 血清替代品是一种半定义的血清替代物，PALL Ultroser™ G包含6类真核生物细胞生长所必须的营养物质，包括粘附因子，结合蛋白，生长因子，微量矿物元素，荷尔蒙，维生素等。Pall 15950-017 Ultroser G血清替代物与胎牛血清相比，它的生物活性是胎牛血清的5倍，一般使用浓度是2%，而血清是10%～20%的浓度，由于近一年，胎牛血清价格猛涨，很多细胞培养实验室和间充质干细胞培养实验室的胎牛血清浓度调整到：5%～10%的浓度。Pall 15950-017 Ultroser™ G serum substitute 20mL 血清替代物是干粉状包装，真正小而强大，很容易储存。更为重要的是，对于很多干细胞培养和MSC间充质干细胞培养的实验来说，保持：组分的一致性，批次的稳定性，使实验结果的可重复性提高显得尤为重要。Pall 15950-017 Ultroser G血清替代品恒定不变的生物活性，更低的蛋白含量使中国广大生命科学领域内的科研人员无需再为内毒素和血红蛋白而苦恼。Pall Ultroser G血清替代品与常规细胞培养基相比，有更长的保质期，从生产日期算起有4年，科研人员可以批量采购Pall Ultroser G血清替代物。
Ultroser™ G serum substitute can successfully replace FCS (fetal calf serum) in cell culture medium. It is designed for the in vitro culture of anchorage-dependent cells. It is specially tested as the primary culture from amniotic liquid cells and is designed to confirm their ability for karyotyping.
Ultroser G serum substitute is CE mark-certified.
