Trisomy 13 Standard for counting based assays, 5% fetal fraction, 125ng in 5mL plasma

A 125 ng cfDNA standard representing Trisomy 13 at a 5% fetal fraction, pre-spiked into 5 mL of DNA-depleted human plasma. This commutable format accurately mimics a clinical specimen for whole-process NIPT assay validation.

Serves as a full-process positive control for counting-based NIPT assays. It is used to validate the entire workflow, from cfDNA extraction and library preparation to sequencing and data analysis, for the detection of Trisomy 13.

This ready-to-use format in a clinically relevant matrix is ideal for validating sample preparation, assessing extraction efficiency, and performing routine quality control. For optimal stability, store as recommended.
