Papain, 100 mg

A plant-derived cysteine protease from STEMCELL Technologies, this papain preparation is purified from Carica papaya latex and supplied as a 100 mg vial for research use only applications in cell biology and tissue dissociation workflows. This lyophilized enzyme preparation is widely used for gentle enzymatic dissociation of neural and other sensitive tissues, producing high-viability single-cell suspensions suitable for downstream cell culture, flow cytometry, and primary cell isolation protocols. The enzyme cleaves peptide bonds with broad specificity and remains active across physiological pH ranges, making it compatible with standard cell isolation buffers. Store the vial at -20°C upon receipt to preserve enzymatic activity, and avoid repeated freeze-thaw cycles by aliquoting into single-use portions. Researchers commonly employ this preparation for dissociating hippocampal and cortical tissue, isolating cardiomyocytes, and preparing cell suspensions from various solid tissues. Each batch is quality-controlled to ensure consistent specific activity, supporting reproducible outcomes in neuroscience research, developmental biology studies, and regenerative medicine workflows.
