Implementing CRISPR-Cas9 Technology using RJH Reagents 

CRISPR technologies have been increasingly utilized in research and therapeutic development. RJH has been collaborating with leading CRISPR experts to validate our reagents for CRISPR applications. The following shows Prime-Fect and other RJH reagents used for gene editing using pDNA-based CRISPR-Cas9 technology.
