Abstract

The invention relates to a PROM1-KO mouse model construction method and application thereof. A mouse model is a PROM1 gene knockout mouse. A PROM1 gene knockout mouse model is constructed based on CRISPR / Cas9 gene knockout technology. The construction method comprises the following steps: step one, designing sgRNA and Cas9mRNA, transcribing sgRNA and Cas9mRNA into mRNA in vitro, and microinjecting the active sgRNA and the active Cas9mRNA into mouse fertilized eggs to obtain PROM1-KO mice; and step two, identifying a PROM1-KO mouse animal model. The PROM1-KO mouse animal model is firstly constructed based on the CRISPR / Cas9 gene knockout technology, and a convenient, reliable and economical animal model is provided for researching the relationship between PROM1 and diseases such as hereditary retinopathy and tumors.

Description

technical field

[0001] The invention relates to the technical fields of molecular biology and biomedicine, in particular to a method for constructing a PROM1-KO mouse model and its application. Background technique

[0002] The CRISPR / Cas system is developed from the adaptive immune system of bacteria and archaea against foreign viruses or plasmids, including three different types, of which the Type II CRISPR / Cas system has only one subunit of the DNA endonuclease Cas9 , the structure is the simplest, so it is the most widely used. In addition to the Cas9 protein, the system also includes two short CRISPR RNAs (crRNAs) and trans-activatingcr RNAs (tracrRNA). The mature crRNA-tracrRNA complex can guide the Cas9 protein to the target sequence through complementary base pairing, and specifically cut the DNA double strand near the PAM (protosp aceradjacent motif) to form a DSB (double strand break). DSB can be repaired in two ways, one is Non-Homologous End Joining (NHEJ) DNA ...
