I'm using the TaqMan hPSC Scorecard Panel. How do I load the samples onto a 384-well plate if I don't have a multichannel pipette?
You can load samples using a single channel pipette, but this method is time-consuming and may increase pipetting error. We strongly recommend that you use an 8- or 16-channel multichannel pipette. You also can dispense samples using automated systems, with the understanding that additional sample will be required to compensate for the dead volume.
Why should I set up cDNA synthesis in 8 wells of a 96-well plate or in 8-well PCR strips when using the TaqMan hPSC Scorecard Panel?
Setting up your cDNA synthesis in 8 wells of a 96-well plate or in 8-well PCR strips facilitates sample loading of the 96-well and 384-well hPSC Scorecard Panel plates.
Can I analyze somatic non-pluripotent primary cells with the TaqMan hPSC Scorecard Panel?
Somatic non-pluripotent primary cells, such as the parental lines used for iPSC generation, are not pluripotent in nature and their scores will be low. However, the expression of lineage markers will largely rely on homogeneity of the cells. Note that the markers in the panel are designed to evaluate early germ layer specification and not any particular terminally differentiated state.
Does the reprogramming method affect the TaqMan hPSC Scorecard analysis results?
Minor differences in gene expression profiles are sometimes observed based on the reprogramming method, but in general the hPSC Scorecard analysis results do not change significantly for lines derived using various reprogramming methods. This was tested with ESC and iPS derived using episomal or Sendai-based reprogramming systems before and after seven days of spontaneous differentiation. Cells were grown in KSR-based media on irradiated MEFs prior to removal of FGF for EB formation.
Will the presence of Sendai virus affect my TaqMan hPSC Scorecard analysis results?
The presence or absence of Sendai virus in established iPSC clones does not have an impact on pluripotency and hence on TaqMan hPSC Scorecard analysis results.

'Although significant advancement has been made in the induced pluripotent stem cell (iPSC) field, current methods for iPSC derivation are labor intensive and costly. These methods involve manual selection, expansion, and characterization of multiple clones for each reprogrammed cell sample and therefore significantly hampers the feasibility of studies where a ...

'Induced pluripotency is a promising avenue for disease modeling and therapy, but the molecular principles underlying this process, particularly in human cells, remain poorly understood due to donor-to-donor variability and intercellular heterogeneity. Here, we constructed and characterized a clonal, inducible human reprogramming system that provides a reliable source of cells ... More
