Before the Tet-One systems were developed, our Tet-On and Tet-Off products all required two separate vectors: one to introduce the doxycycline-responsive transactivator protein into your target cells, and the other to introduce the inducible promoter controlling your gene of interest.
Before the Tet-One systems were developed, our Tet-On and Tet-Off products all required two separate vectors: one to introduce the doxycycline-responsive transactivator protein into your target cells, and the other to introduce the inducible promoter controlling your gene of interest. The Tet-One Systems provide both of these components on a single vector. The Tet-On 3G transactivator is expressed in the forward direction from the human phosphoglycerate kinase 1 promoter, and the cloned gene of interest is expressed from the PTRE3GS promoter in the reverse orientation. Compared to the two-vector Tet-On 3G systems, all previously published all-in-one vectors have shown a low signal-to-noise ratio, typically providing only 50- to 100-fold induced expression, even in selected clones. Our Tet-One systems are based on an all-in-one design that has shown up to 25,000-fold induction (Heinz et al. 2011).

比如你用anti-MHC-II，mouse IgG1-FITC，那同型就用非特异性的mouse IgG1-FITC，同样浓度
请问：同型对照应该怎么设？
不买专门的IgG2Bisotypecontrol，而用其他的抗体，
比如mouseanti-humanCD117，Igclass也是IgG2B，可以吗？
阴性对照(Isotype Control)：非特异荧光的强弱取决于抗体浓度、单克隆荧光抗体特异性和纯度，应与试验管抗体相对应。在多色分析时，同型对照应与其它抗体同时使用，以避免补偿造成的误差
血小板体外活化试验：使用正常人活化标本作为阳性质控；使用正常人未活化标本作为阴性质控
血小板自身抗体检测：使用含有已知血小板抗体的血清与血小板孵育，作为阳性质控；使用不含血小板抗体的血清与血小板孵育，作为阴性质控
血小板表面抗原缺失：如巨血小板症血小板表面CD42a/CD42b缺失，血小板无力症血小板表面gpIIb/IIIa，即CD41/CD61缺失或异常。使用正常人标本做阳性对照，抗体的同型对照做阴性对照
