CRISPR reagents are the biological components used in CRISPR-based gene editing systems. CRISPR, short for Clustered Regularly Interspaced Short Palindromic Repeats, originated from a natural defense mechanism found in bacteria. Scientists adapted this system to precisely edit DNA in living cells.
CRISPR reagents exist to make gene editing accurate, repeatable, and controllable. These reagents allow researchers to target specific DNA sequences, introduce changes, and study gene function in a controlled laboratory environment. Over time, CRISPR reagents have become essential tools in molecular biology, genetic engineering, biotechnology research, and biomedical studies.
Unlike earlier gene-editing methods, CRISPR-based approaches rely on fewer components and simpler workflows. This has contributed to wider adoption across academic research institutions, biotechnology labs, and clinical research environments.
