我们开发了一种方法,在小鼠研究模型中检测肥胖基因的单点突变。该方法快速、易于进行,适用于肥胖和糖尿病相关研究,特别是在资源有限的情况下,以识别和区分野生型小鼠和携带基因突变的小鼠。由于瘦素的自发缺乏,肥胖/肥胖小鼠是糖尿病研究中最常用的实验动物模型之一。在本研究中,我们报道了一种快速、简便的基因分型方法,利用四引物扩增难治突变系统-聚合酶链式反应(ARMS-PCR)来区分突变等位基因和野生型基因。不同基因型的扩增产物在1.5%琼脂糖凝胶上清晰可见。这种方法可以作为一种有价值的工具来区分育种目的的基因类型,维持动物群体,控制动物设施中的可用空间,并为动物实验识别合适的个体。
We developed a method to detect a single-point mutation in an obese gene in a mouse research model. The method is quick, easy to conduct, and suitable for obesity and diabetes-related research, especially in settings with constrained resources to identify and differentiate wild-type mice from mice carrying a gene mutation. Due to spontaneous deficiency in leptin, ob/ob mice are one of the most commonly used experimental animal models in diabetes research. In this study, we reported a quick and easy-to-conduct genotyping method using tetra-primer amplification refractory mutation system-polymerase chain reaction (ARMS-PCR) to differentiate mice with a mutated allele from the wild-type genotype. The amplicon patterns of different genotypes are clearly visible and distinguishable on 1.5% agarose gel. This method can serve as a valuable tool to differentiate genotypes for breeding purposes, to maintain animal colonies, control the available space in the animal facility, and identify appropriate individuals for animal experiments.
