OVERVIEW MONKEYPOX CONTROLS SARS-COV-2 CONTROLS RESPIRATORY VIRUS CONTROLS RESOURCES
Overview

Trusted, accurate and safe controls for
a wide-range of applications

The recent Coronavirus pandemic has led to the unprecedented need for diagnostic tests for detecting the presence of SARS-CoV-2 and other Respiratory viruses in a variety of sample types. To address this need, laboratories around the world need high quality tools to enable them in catering to this rapidly expanding requirement for testing. 

 

Reproducible, Quality Results

Positive controls provide quality control measures for a wide range of applications from diagnostic assay development to day-to-day testing. This includes the verification and validation of diagnostic tests of both next-generation sequencing (NGS) and reverse transcription polymerase chain reaction (RT-PCR) assays. 

 

A Safe and Effective Alternative to “Live Virus”

Controls based on viral nucleic acids extracted from either an infected patient or from live virus propagated in cell culture have safety and security concerns. Synthetic controls created through gene synthesis broaden access across diverse strains while mitigating risk.

 

Flexible formats for your applications

Choose from Standard, Assay Ready, or Encapsuled Control formulations. The standard format provides the controls at high concentration in a frozen liquid formulation. The Assay Ready Controls are provided as a dried pellet that increases stability. Just as protein encapsulation of viruses offers more stable molecular storage, Twist’s The Encapsulated Control products leverage a metal capsule sealed around a desiccated pellet to enhance stability of the RNA controls.
 
Both the Assay Ready and the Encapsulated formulations are single use controls. The Assay Ready format allows for shipping at ambient temperatures and storage in standard freezers. The enhanced stability of the Encapsulated controls enables extended shelf life and both ship and store at room temperature. Ambient shipping reduces cost and increases accessibility for researchers across the globe.

Monkeypox Controls
Monkeypox Controls

Twist’s Synthetic human Monkeypox Virus (hMPXV) Controls are based on sequences from either the Congo Basin (CB) or West African (WA) clades of hMPXV and provide coverage of ≥80% of the viral genome. As a result, these controls support the design of custom assays targeting regions of the genome relevant to orthopoxvirus research and can be used for both amplicon and capture-based detection methods. Twist’s hMPXV controls have been validated and are compatible with CDC recommended real-time PCR testing procedures for monkeypox detection. Control 1 and Control 2 are composed of 154 and 151 overlapping 1.8kb fragments, respectively, which tile the genome at an interval of 900bp. Each control is present at  copies and provided at a concentration of approximately 100,000 copies/uL. The figure on the right shows a taxonomic relationship between the WA and CB clades of hMPXV as well as other orthopoxviruses. Please contact your local sales representative for more information.

SARS-CoV-2 Controls
The use of positive controls in quality control

Twist has created synthetic RNA controls for several viral genomes. These 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. The Twist Assay Ready Synthetic SARS-CoV-2 RNA Control was developed in partnership with the US CDC and integrated into the CDC Influenza SARS-CoV-2 (Flu SC2) Multiplex Assay, which tests for influenza A, B and SARS-CoV-2 simultaneously. The Twist Assay Ready Synthetic SARS-CoV-2 RNA Control is now available for customers outside the CDC. 


Twist Bioscience Encapsulated Control products offer a unique storage and delivery method for Twist’s established Synthetic SARS-CoV-2 RNA controls. Just as protein encapsulation of viruses offers more stable molecular storage, Twist’s Encapsulated Control products leverage a novel method to seal a metal capsule around a desiccated pellet to enhance stability of the RNA controls. Due to the enhanced stability, they can be shipped and stored at room temperature, reducing cost and improving accessibility globally. The Encapsulated Controls are sold in a rack of 16 or 96 tubes, are single use, and have a 5-year shelf life from the date of manufacture.
