endo-BCN-PEG6-t-butyl ester is a click chemistry linker. The hydrophilic PEG spacer increases solubility in aqueous media. The BCN group can react with azide-tagged molecules. The protected carboxyl group (COOH) prevents self coupling or polymerization under standard acid/amine or acid/hydroxyl coupling conditions. It can be converted to free acid under acidc condition. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

The recovery rate of different concentration samples in the linear range is between 70% and 130%.
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%.
Fig 5. Only one Reagent for qPCR MIX.

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).
Mastitis is the single most costly disease of dairy cattle resulting in the reduction of milk yield and quality. The inflammation of the utter is mainly caused by infection of various bacteria. Streptococcus uberis is a gram-positive bacterium that is known worldwide as an environmental pathogen responsible for a high proportion of cases of mastitis in lactating cows and is also the predominant organism isolated from mammary glands during the non-lactating period. Often it is resistant to treatment and causes persistent high somatic cell counts without clinical mastitis.
Storage Conditions and Product Stability All kit components can be stored for 2 years after the date of production without showing any reduction in performance.
All kit components should be stored at -20°C upon arrival.
For isolation and cultivation of Listeria monocytogenes.
Principle:
Peptone provide carbon and nitrogen sources; yeast extract powder and starch provide carbon and nitrogen sources, vitamins and growth factors; sodium chloride maintains osmotic equilibrium; glucose carbon source; agar as medium coagulant.
