GenCRISPR™ Ultra ErCas12a-3NLS, His-tag, is a revolutionary CRISPR-associated nuclease that delivers highefficiency editing across challenging systems, including plant cells and hard-to-transfect primary T cells. Unlike traditional editors, GenCRISPR™ Ultra ErCas12a-3NLS, His-tag, operates with minimal off-target effects while maintaining robust on-target activity – even in notoriously difficult-to-edit genomes. For plant biology, broad PAM compatibility and high editing efficiency of GenCRISPR™ Ultra ErCas12a-3NLS, His-tag, enable seamless gene knockouts, insertions, and multiplexed modifications in protoplasts, callus, and regenerated plants. Its low toxicity and high specificity reduce screening workloads, accelerating trait development. In primary T cell engineering, GenCRISPR™ Ultra ErCas12a-3NLS, His-tag, outperforms conventional nucleases by achieving high knock-in efficiency without compromising cell viability.
