NEXEL's iPSCs were reprogrammed using the Sendai virus method with the 4 Yamanaka trancription factors (Oct3/4, Sox2, c-Myc, Klf4)

NEXEL uses a single hiPSC line for all commercially available products currently. We are actively testing new cell lines and are preparing cell line panels for the future.

'The expiry date is indicated on the product's label. The cell culture media should be used within a month after thawing. 

We highly recommend against attempting to passage the cells as they do not proliferate once differentiation is completed and passaging the cells will result in cell death.

It was developed to mimic the primary cell and is easier for long-term culture than the primary cell. Also, unlike the primary cell, it shows consistent quality by batch.

We do not recommend to refreeze the cell. The viability/cell return on such process will be very low.

NEXEL's cell products are all of a purity higher than 90% when assessed by flow cytometry. However, when tested by Immunocytochemistry there are rarely other cell types observable.
