双语例句
Study on the Action of Decreasing level of Isotype Cysteine for High Blood Viscosity
降低同型半胱氨酸水平对高黏血症作用的研究
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
选用和特异性抗体同种亚型的,同样荧光素标记的抗体,采用同样的染色步骤染同样浓度的细胞。然后上机检测。如果细胞有非特异性的结合,那同型对照的荧光强度可能会比未染色的阴性对照要高一些。
同型对照只用于那种阳性和阴性之间没有明确分解的情况。如果阳性细胞群非常清楚,是不需要同型对照的。另外,在多色同染的情况下,也不采用同型对照,而是采用FMO(fluorensence minus one)对照。
另外,对于同型对照的使用,也有很多反对意见。就算是同型抗体,也可能会有不同的亲和力,并不一定就能真实反应非特异性的结合。
