Characterization and Quality Control

Proper characterization and quality control are essential for ensuring the integrity, reliability, and safety of iPSC lines. Our comprehensive process includes:

Cell Morphology Evaluating growth patterns of typical iPSCs
Molecular Analysis Confirming pluripotency-associated gene expression using PCR and RNA sequencing
Growth and Viability Assessment Monitoring cell proliferation and health
Microbial and Fungal Sterility Testing Detecting and eliminating contaminants
Mycoplasma Testing Preventing contamination by mycoplasma species
Human Pathogen Testing Screening for pathogens to ensure safety
Identity Testing Microsatellite analysis for genetic match verification
Cytogenetic G-Banded Karyotype Ensuring chromosomal stability
Microarray Genotyping Confirming genetic authenticity and stability
Confirmation of Integration-Free Reprogramming Verifying no genomic integration
Stem Cell Surface Marker Assessment Using immunocytochemistry, flow cytometry, and alkaline phosphatase staining
In Vitro Embryoid Body (EB) Assay Confirming pluripotency through 3D aggregate testing
Pluripotency and Tri-Lineage Differentiation Potential Using the Applied Biosystems TaqMan hPSC Scorecard Panel to evaluate differentiation into ectoderm, mesoderm, and endoderm germ layers

Coriell’s commitment to meticulous quality control ensures that every iPSC line meets the highest standards of reliability and reproducibility.
