The resDetect™ Cas9 ELISA Kit (Residue Testing) provides a reliable method for the quantitative detection of Cas9 residues in cell therapy products. Designed for use during in-process testing and final product release, this sandwich-ELISA kit supports quality control in CRISPR-based therapeutic manufacturing by monitoring residual nuclease levels. The assay utilizes a microplate pre-coated with anti-Cas9 antibody to capture Cas9 from standards and samples, followed by detection with a biotin-conjugated antibody and streptavidin-HRP. This kit is intended for research use only.
