AI Technical Summary

Problems solved by technology

Both types of software build a general model. However, due to the large heterogeneity between different species and different cells, the prediction performance of existing software is not very good, and because different experimental conditions The heterogeneity of sgRNA has a certain impact on the digestion efficiency of sgRNA, and the general model evaluation accuracy is relatively low

Abstract

The invention relates to a CRISPR/Cas9-based sgRNA design method. The method is characterized by comprising the following steps of obtaining the value of enzyme digestion efficiency of sgRNA and corresponding Cas9; building a personalized sgRNA design model; measuring the quality of the built personalized sgRNA design model by applying an NDCG algorithm and updating a database; and designing sgRNA and giving out an assessment value of each sgRNA. Compared with the prior art, the method has the characteristics of high accuracy, complete characteristics, wide application range and wide data analysis range.

Description

technical field [0001] The invention relates to the field of gene editing research, in particular to a method for designing sgRNA based on CRISPR / Cas9 gene editing technology. Background technique [0002] With the development of molecular biology, people have a deeper understanding of the constituent elements of life, but there are still many puzzles about the mechanism of life processes, especially the healing mechanism of certain diseases. The relationship between genes and phenotypes, and the mutual influence between genes, urgently require an engineering technology that can quickly knock out and insert genes in vivo. The CRISPR / Cas9 system appeared in time to meet the needs of scientific researchers. [0003] The CRISPR / Cas9 system (Clustered regularly interspaced short palindromic repeats / CRISPR-associated protein 9) is a gene editing tool with simple operation and wide applicability. The whole system is mainly composed of a nuclease (Cas9) and an RNA (sgRNA) that gu...
