Waters has introduced the OMICS Guard™ CRYO Preservation Buffer, a cryopreservation solution designed to maintain cellular and molecular integrity for downstream single cell and multiomics analyses. The buffer supports long term storage of intact cells, whole blood, and tissue in liquid nitrogen and is intended to preserve gene expression, protein epitopes, and chromatin accessibility for later RNA, protein, and chromatin based analyses. It is compatible with the Rhapsody system and is suited for laboratories that need to store and transport samples across sites or time points while maintaining consistency in downstream data quality.
