Gene editing

The Genome Innovation Hub continually develops a number of protocols and procedures while undertaking our collaborative projects. Below are a selection of detailed developments useful to researchers undertaking Gene editing procedures in the laboratory.

Developments

Cas9 protein expression, purification and validation

CRISPR-Cas (Clustered Regularly Interspaced Short Palindromic Repeats-CRISPR associated) technologies enable scientists to accurately modify the genome of cells and organisms. CRISPR-Cas9 and CRISPR-Cas12a enzymes are the most widely studied of the RNA-guided endonucleases used for genome editing. To help reduce costs of our genome editing research projects, we have established an "in-house" protocol for purifiying and functionally testing a range of Cas9/Cas12a endonuclease which are attached to various affinity tags.

Genome editing of mammalian cells using RNP

Currently in development at GIH is a basic workflow of genome editing in mammalian cells including guide RNA design, transfection using electroporation method to deliver RNP to the cell and editing analysis using a T7E1 assay. Commercial source of Cas9 and synthetic guide RNA was used to eliminate the workload of sub-cloning or in vitro transcription of guide RNA and achieve a high efficiency.
