Our reagents are recommended for newborn screening by key opinion leaders. Extracta DBS in combination with ToughMix chemistry enable simple and cost effective processing of DNA from dried blood spots (DBS) for molecular testing using qPCR.

Quantabio reagents streamline workflows, improve performance and reduce testing costs in Public Health Labs for multiple testing applications

What Customers Say

We make our technology choices based on several criteria, such as ease of use, consistent performance, and applicability to challenging samples. I have tried several alternatives and the combination of Quantabio Extracta DBS and ToughMix® reagent provided the best overall assay performance when we performed real-time PCR assays to measure T cell receptor excision circles (TRECs) used for SCID screening.

Customer Profile Story

Mei Baker, MD, FACMG
Co-Director of Newborn Screening
We used the qScript XLT 1-step RT-qPCR ToughMix to reliably and very quickly identify an experimental drug candidate and demonstrate its efficacy to correct the debilitating effect of an inherited disease. The immediate success and impeccable performance of this mix shortened our labs time to result and confirmation easily by 2-3 months.
