The UCB samples were mixed with the Hetasep solution (StemCell Technologies, Vancouver, Canada) at a ratio of 51, and then incubated at room temperature to deplete erythrocyte counts. The supernatant was carefully collected and mononuclear cells were obtained using Ficoll density-gradient centrifugation at 2,500 rpm for 20 min. The cells were washed twice in PBS.* o2 Y$ k4 P2 I
疑惑1.Hetasep solution是指的红细胞裂解液么 ?, f3 @' z; _- c
2.The cells washed twice in PBS.?需要离心不?转速?1000RPM/M*5MIN ?5 K+ D- k9 d/ ^& h+ U" _: h1 b- J
求高手指点一下!!!; `, J+ @. `0 `$ s0 B6 P( ?$ `) z0 z) Q
