About InVivoMAb anti-mouse/human/rat v-H-Ras
The Y13-238 monoclonal antibody reacts with human, mouse, and rat v-H-ras (within amino acids 120-138) and does not react with v-K-ras. v-H-ras binds GTP/GDP and has intrinsic GTPase activity. Ras proteins alternate between an inactive form bound to GDP and an active form bound to GTP, activated by a guanine nucleotide-exchange factor (GEF) and inactivated by a GTPase-activating protein (GAP). Under normal conditions, Ras family members influence cell growth and differentiation events. Mutations in the Ras family of proto-oncogenes are very common, being found in 20% to 30% of all human tumors. Ras point mutations are the single most common abnormality of human proto-oncogenes. The Y13-238 antibody does not neutralize ras GTPase binding and hydrolysis in vivo or in vitro.

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。
