Opentrons Thermocycler GEN2 Seals are adhesive-backed Ethylene Propylene Diene Monomer (EPDM) seals designed for use with the fully-automated Thermocycler Module GEN2. They come in a package of 10 seals. These seals need to be applied to the hood of the Thermocycler and can be reused up to 20 times. Opentrons Thermocycler GEN2 Seals need to be sterilized before each use.
Note, if you have a Thermocycler Module GEN1, please use the Thermocycler GEN1 Seals.

Norovirus is known to cause acute gastroenteritis. It is a small (27-38 nm), round, nonenveloped RNA virus belonging to the Caliciviridae family and is responsible for over 80% of non-bacterial outbreaks of gastroenteritis in the world. It affects individuals of all ages, with a distinct seasonal link to winter. It has a genome of 7.6 kb that is positive sense and has a single stranded linear confirmation. It encodes a major structural protein (VP1) of about 58 to 60 kDa and a minor capsid protein (VP2). Transmission occurs predominantly through ingestion of contaminated water, food and airborne transmission, as well as contact with contaminated surfaces. The ease with which norovirus is transmitted and the low infectious dose required to establish an infection results in extensive outbreaks in numerous environments, such as hospitals, hotels and schools. There is no antiviral drug available to treat this infection and little is known about its pathogenicity. However, it has been observed that the virus can be taken up by enterocytes where translation of viral nonstructural proteins can occur; it damages and alters intestinal microvilli, leaving them blunt and broadened, thus inhibiting absorption; it causes crypt cell hyperplasia and also leads to apoptosis of enterocyctes. An incubation period of 24-48 hours is usual. Infection is characterized by the acute onset of nausea, vomiting, abdominal cramps, aching limbs, raised temperature and diarrhoea that generally last for about 48 hours. However, more severe and prolonged infection may be observed in children and the elderly. There are five recognized norovirus genogroups, of which three (GI, GII, and GIV) are known to affect humans and, since 2002, variants of the GII.4 genotype have been the most common cause of norovirus outbreaks. There have been 31 different genotypes identified within the genogroups, with a wide degree of genetic variability present even within each genotype.

Kit Performance
Fig 1. Only three steps will be need for Sample Preparation and only 20 minitutes will be taken for Sample Preparation.
Fig 2. Seven concentration samples of 0.3fg/μL, 3fg/μL, 30fg/μL, 300fg/μL, 3pg/μL, 30pg/μL, 300pg/μL were detected. CV of each concentration was < 30%, Regression coefficient associated with standard solutions was 0.99992, and amplification efficiency was 100.370%.
Fig 3. Five concentration samples of 0.1 fg/μL, 0.3 fg/μL, 0.5 fg/μL, 1 fg/μL and 3 fg/μL were detected, and 10 multiple wells were detected for each concentration. The CV of concentrati on values of samples with 0.3 fg/μL and above concentrations were less than 30%.
Fig 4. DNA recovery can be determined by including samples spiked with known DNA amounts which are prepared from the corresponding DNA standards. Typically, the range for this value varies from 70% to 130%.

Note: Price not include shipment & duty, contact us to get full quote. The resDNASEQ CHO Residual DNA Quantitation kit is designed for the quantification of residual DNA from CHO, in cell lines which are used for production of biopharmaceutical products. The Ducky Bio residual DNA CHO Assay, based on proven real-time qPCR technology, makes testing of residual DNA from the Chinese hamster ovary (CHO) cell line rapid, specifc. The PCR-based assay is sensitive and specific for DNA from the CHO cell line and not subject to detection of human or environmental DNA that might be introduced during sample handling. The kit was developed to meet the sensitivity requirements defined by WHO (10 ng CHO DNA per therapeutic dose).
