HighQC™ Human Embryonic Stem Cells E1

Frequently Asked Questions

• Can specific individual cell lines (e.g., a single 46,XY/O⁺ line) be ordered instead of a mixed collection?

  Yes. Specific individual hESC lines can be ordered separately rather than as a mixed collection. For each individual cell line, an independent Certificate of Analysis (CoA) and full characterization data are provided, including karyotype analysis, STR authentication, pluripotency marker expression, and sterility and mycoplasma testing.

• What are the expression levels of key pluripotency markers in individual lines?

  HighQC™ hESC lines exhibit stable and robust pluripotency marker expression under undifferentiated culture conditions. Typical expression profiles include: Oct4 (POU5F1) >90% positive, SSEA-4 >90% positive, and SSEA-1 <10% positive, consistent with high pluripotency and minimal spontaneous differentiation.

• Are directed differentiation efficiency data (e.g., neural, cardiac, or hepatic) available for individual lines?

  All HighQC™ hESC products undergo standardized trilineage differentiation validation, confirming their capacity to differentiate into ectodermal (neural), mesodermal (cardiac), and endodermal (hepatic) lineages. Due to inherent variability among different cell lines, donor backgrounds, and differentiation protocols, uniform quantitative efficiency percentages are not provided for individual lineages.
