mTeSR1 Complete Kit Without Phenol Red

This complete cell culture medium from STEMCELL Technologies is formulated for the feeder-free maintenance of human embryonic stem (ES) and induced pluripotent stem (iPS) cells. It is a highly specialized, serum-free medium made with pre-screened raw materials, providing batch-to-batch consistency and homogeneous, undifferentiated phenotypes with robust feeder-free protocols.

The formulation supports established workflows ranging from cell line derivation to differentiation, and is offered without phenol red for applications in which the indicator dye is undesirable. According to the supplier, the medium has been used to maintain hundreds of ES and iPS cell lines in over 40 countries, and is described as the most widely published feeder-free cell culture medium for human pluripotent stem cells.
