NH-bis(PEG2-propargyl) is a multi-branched linker with two terminal propargyl groups and an amino group. The propargyl groups reacts with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry to yield a stable triazole linkage. The amino group is reactive with carboxylic acids, activated NHS esters, and carbonyls. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Features of the sDNASEQ E.coli Residual DNA Quantitation kit include:
Simpler and Rapid
Only three steps will be need for Sample Preparation and All components of the Sample Preparation Kit can be stored at room temperature.
Only one Reagent for qPCR;
Only 1.5 hours will be needed for the whole test.
Accurate
Perfect amplification curve, good amplification efficiency and good precision.
Highly sensitive quantitation using proven TaqMan™ real-time qPCR technology.

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 5fg/μL, 10fg/μL, 20fg/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 0.99975, and amplification efficiency was 100.068%.
Fig 3. Four concentration samples of 5fg/μL, 10fg/μL, 20fg/μL, and 30fg/μL were detected, and 10 multiple holes were detected for each concentration. The detection values of 5fg/μL and above were CV <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.

Note: Price not include shipment & duty, contact us to get full quote. The resDNASEQ E.coli Residual DNA Quantitation kit is designed for the quantification of residual DNA from E. coli, in cell lines which are used for production of biopharmaceutical products. The resDNASEQ E.coli Residual DNA Quantitation kit use TaqManTM quantitative PCR to perform rapid, specifc quantitation of femtogram levels of residual host-cell or plasmid DNA. The kit was developed to meet the sensitivity requirements defined by WHO (10 ng E. coli DNA per therapeutic dose).
Sulfo DBCO-PEG4-Maleimide is a water-soluble click chemistry reagent with a maleimide group and a DBCO moiety. The hydrophilic PEG spacer arm improves solubility in aqueous buffers. Maleimide group specifically and efficiently reacts with thiols to form stable thioether bonds. The low mass weight will add minimal spacer to modified molecules and will enable simple and efficient incorporation of DBCO moiety onto cysteine-containing peptides or other thiol-containing biomolecules. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
