BMEM Cardiomyocyte Selection is a ready-to-use, highly optimized, chemically defined, and animal origin-free (AOF) medium designed for the selective enrichment of hiPSC-derived cardiomyocytes.•Rapid Purification: Efficiently eliminates non-cardiomyocytes to yield highly enriched cultures (>95% TNNT2+) within just 4 days.•High Viability: Formulated to support robust cell health and strong contractile activity during the selection process.•Workflow Integration: Designed for post-differentiation use with the BMEM Protein-Free Cardiomyocyte Differentiation Kit and BMEM growth media (Human Primed or Max).•Matrix Compatibility: Compatible with standard matrices including Matrigel, Geltrex™, Vitronectin, and Laminin-521 (e.g., Acro Biosystems™).•Quality Control: Each lot is performance tested on hiPSC-derived cardiomyocytes and sterility tested.
