Biolaminin 521 Cell Culture Substrates
Biolaminin 521 is a full-length, human recombinant laminin that recreates the natural stem-cell niche for robust, reproducible culture of human pluripotent stem cells. Available in both research-grade (MX) and cell-therapy grade (CTG) formats, it provides a defined, animal-origin-free substrate that supports reliable adhesion, survival, single-cell passaging, and long-term expansion. Manufactured in human suspension cell lines and rigorously quality-controlled for purity, sterility, and safety, Biolaminin 521 enables consistent feeder-free workflows from basic research through clinical-scale cell manufacturing.
