Background | IL-4 is a pleiotropic cytokine that is produced by activated T cells, mast cells, and basophils. IL-4 elicits many different biological responses but has two dominant functions. The first is regulating differentiation of naïve CD4+ T cell to the Th2 type. Th2 cells produce IL-4, IL-5, IL-10, and IL-13, which tend to favor a humoral immune response while suppressing a cell-mediated immune response controlled by Th1 cells. The second is regulating IgE and IgG1 production by B cells. |

Q1:组织样本检测胞内指标的注意事项有哪些?
①所有样本管均需与实验组一样进行固定破膜,如blank对照,单标组,fmo-iso;②各组固定破膜时间尽量不要相差太久,如果样本量多,建议分批次操作;③对于肿瘤组织样本,由于检测目的细胞量少,需考虑增加抗体用量,上机时间数至少100万个;④建议增加75um微米孔径滤网进行二次过滤,提高免疫细胞纯度和含量;⑤由于刺激阻断时间较长,需要在刺激阻断时间结束前注意无菌操作。

Q2:流式抗体样本什么时候用无菌的耗材?
后续需要进行细胞培养操作的实验都需要使用无菌耗材,如胞内因子检测或流式分选实验。
Q3:人外周血检测胞内因子的注意事项有哪些?
①选择肝素抗凝管;②样本制备:a.人外周血样本:提前稀释红细胞裂解液,现配现用;b.PBMC样本:将样本及试剂复温到18~20℃以后再进行实验;实验环境温度控制在18~20℃;收集的新鲜人血尽量在1 h内进行PBMC分离; 加入血液时,避免冲散分层液面;加完后不要混匀或晃动管。③采血过程中,血样在肝素抗凝管中充分摇匀,避免血凝(肝素抗凝管保存时间一般不要超过12h);④裂红时间不超过5min,建议做预实验摸索一下最佳时间;⑤无菌操作;⑥刺激和阻断时间建议通过预实验摸索。
