Very good source of control RNA
Control RNA for identifying potential RNA modifications
The RNA is high quality and was far more convenient than in vitro transcription of the entire viral gRNA.

The MVP of 2020 SARS-CoV-2assay development!
Assay development
This product is simple to use, simple to buy, and excellently packaged and orderable. Customer support answered all questions fully and quickly and was a very easy process. This is one of the most straight forward companies I have had to deal with and was the easiest and most important material I had to routinely buy during 2020. Materials always shipped same or next day and were received the next business day. Our team would not have been able to develop and perfect our SARS-CoV-2 assays without this material.

Twist has created synthetic RNA controls for several viral genomes, and variants were selected to cover a wide range of sequence diversity. Each control consists of six non-overlapping 5 kb fragments generated from Twist Gene Fragments then transcribed into ssRNA. These controls provide coverage of greater than 99.9% of the bases of the SARS-CoV-2 viral genome. The majority of the controls are provided in the standard format which consist of 100 μL at a concentration of approximately one million copies per microliter. Twist also offers certain controls in Assay Ready and Encapsulated Formats that are supplied as a desiccated pellet. The Assay Ready Controls are supplied at approximately two million copies per tube. The Encapsulated Controls are supplied at approximately 50,000 copies per tube.
