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 0.1fg/μL, 0.3fg/μL, 0.5fg/μL, 1fg/μL and 3fg/μL were detected, and 10 multiple wells were detected for each concentration. The CV of concentration values of samples with 0.3fg/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).
Nucleic acid testing (NAT) is the method of choice for detection and quantification of a wide range of micro organisms. Primerdesign manufactures and supplies high quality quantitative real-time PCR kits for the detection and simultaneous quantification of numerous significant pathogens . A copy number standard curve is provided for quantification and an the internal extraction template (DNA or RNA), controls for the quality of the nucleic acid extraction and eliminates false negative results.
The kit is designed with the broadest possible detection profile to ensure that all clinically relevant strains and subtypes are detected. Target sequences are selected by working with data from key opinion leaders in the field. Multiple sequence alignments and unprecedented real-time PCR expertise in design and validation ensure the best possible kit.
Details of the target and priming specificity are included in the individual handbooks above.
Packaged, optimised and ready to use. Expect Better Data.
