在这里,我们展示了在人抗凝血密度梯度离心后,如何通过磁珠分离从外周血单核细胞中分离单核细胞。孵育 5 天后,人单核细胞分化为未成熟的树突状细胞,并准备好在非临床环境中进行实验程序。
这种 CD14 磁珠分离技术的总体目标是从血液中分离单核细胞,以便在体外进一步分化为树突状细胞或巨噬细胞。该方法可以帮助回答免疫学领域关于树突状细胞识别、加工和呈现病原体或抗原的关键问题。该分离程序的主要优点是可以获得 98% 至 99% 纯度的单核细胞群。
演示该程序的是我们工作组的技术人员 Karolin Thurnes。首先根据收到的血液量,将血袋体积分装到无菌的 50 毫升离心管中。根据需要用无菌 Dulbecco 的 PBS 将每管中的最终体积调整至 50 毫升,然后离心样品。
