Defined Bioscience’s HiDef® B8 is a complete, serum-free, defined formulation designed for the feeder-free maintenance and expansion of human pluripotent stem cells (PSCs) in an undifferentiated state.
To better support small-scale experiments and pilot studies, the HiDef® B8 400x Supplement is offered in two vial sizes. Standard vials prepare 500 ml of complete medium, while miniature vials prepare 50 ml, enabling convenient preparation of smaller volumes without excess waste.
HiDef® B8 contains insulin, ascorbic acid-2-phosphate, transferrin, sodium selenite, TGF-β3, NRG-1, and thermostable FGF-2/bFGF. The addition of further components is not required.

HiDef® B8 from Defined Bioscience is a complete, serum-free, defined formulation designed for the feeder-free maintenance and expansion of human pluripotent stem cells (PSCs) in an undifferentiated state. The HiDef-B8 medium is a unique formulation that offers the modern conveniences of a flexible feeding schedule (including weekend-free maintenance) and the ability to choose the matrices and passaging methods that best suit specific applications.
Key characteristics
HiDef® B8 complete medium is a specially formulated defined medium that maintains human pluripotent stem cells in feeder-free and serum-free conditions with reduced hands-on cell culture effort and lower frequency feeding required.
Use appropriate aseptic technique to prepare HiDef® B8 complete medium (DMEM/F12 basal medium + HiDef-B8 400x Supplement). The following example is for preparing 501.25 ml of HiDef-B8 complete medium. If preparing other volumes, adjust accordingly.
NOTE: Thaw supplements or complete medium at room temperature (15 – 25°C) and use immediately. Do not thaw in a 37°C water bath, overnight at 4°C, or on ice.
HiDef® B8 is a complete, serum-free, feeder-free medium for human pluripotent stem cells.
HiDef® B8 maintains PSCs for >50 passages without karyotypic abnormalities, supports weekend-free feeding, and is compatible with multiple matrices and passaging methods.
Yes. PSCs can be transitioned to HiDef-B8 either 1. directly or 2. by gradual adaptation, in active cell cultures or at time of thawing. Please see our transition guide for further details.
Store the 400x supplement at -20°C; prepared complete medium can be kept at 2–8°C for up to 2 weeks.
