Stem Cell Media
- KnockOut™ DMEM and KnockOut™ DMEM/F12: Reduced osmolality to better mimic the natural environment of embryonic tissue
- StemPro® hESC SFM: Defined, serum- and feeder-free stem cell medium for hESC culture
Serum & Serum Replacement
- Fetal Bovine Serum, Embryonic Stem Cell Qualified: Specifically tested to sustain undifferentiated ESC cellular morphology
- KnockOut™ Serum Replacement: Serum-free formulation designed to replace FBS in hESC culture
- KnockOut™ Serum Replacement Xeno-Free: Xeno-free, serum replacement formulation designed for hESC and human iPS cell culture
Matricies & Substrates
- Now Available! GIBCO® Mouse Embryonic Fibroblasts: Isolated from mouse embryos (Strain ICR) at Day E13.5. Expanded and inactivated by gamma irradiation before cryopreservation at passage 2 (P2).
- Geltrex: Geltrex hESC-qualified reduced growth factor basement membrane matrix has been tested to support hESC growth and pluripotency, therefore eliminating the need for customers to test multiple lots
- CELLstart™: The first xeno-free substrate for attachment and expansion of human embryonic, mesenchymal, and neural stem cells that is fully-defined, has better lot-to-lot consistency and is produced under cGMP
KnockOut™ SR Xeno-Free
First xeno-free cell media for the derivation, growth, expansion, & cryopreservation of hESC & human iPS cells
