The ability to verify and characterize the pluripotency of your stem cell culture is critical in moving your research forward.
The PluriTest Characterization Service leverages our Applied Biosystems PrimeView Global Gene Expression Profile Assays in combination with the PluriTest bioinformatics tool to analyze and process the transcriptome of all samples against an extensive and well-characterized reference set, allowing for the global assessment of pluripotency for your submitted samples.
Samples are screened and analyzed with the PluriTest (Online) Analysis Tool, a well-established method for verifying pluripotency with over 16,000 samples analyzed. The online analysis tool utilizes an extensive stem cell model matrix which consists of more than 450 previously characterized pluripotent and non-pluripotent cell and tissue: including 223 human embryonic stem cell lines, 41 induced pluripotent stem cell lines, somatic cells, and tissues.
The PluriTest analysis tool confirms pluripotency via two separate scores: pluripotency and novelty. The pluripotency score is an indication of how strongly a model-based pluripotency signature is expressed in the samples analyzed. The novelty score is assigned based on well-characterized pluripotent stem cells in the stem cell model matrix and indicates the general model fit for a given sample. These two scores are combined into a pluripotency plot to indicate the pluripotency of your samples in comparison to the reference cell lines.
Figure 1. The Pluripotency Plot window provides a visual representation of the pluripotent samples in the analysis. The pluripotency and novelty x/y scatter plot combines the Pluripotency Score on the y-axis with the Novelty Score on the x-axis. The red and blue background hint to the empirical distribution of the pluripotent (red) and non-pluripotent samples (blue) in the reference data set.
