Propargyl-PEG4-CH2CO2H is a linker consisting of a propargyl group with a carboxylic acid group. The carboxylic acid can react with primary amine groups in the presence of activators such as HATU or EDC. The propargyl group can react with azide compounds in Click Chemistry; copper catalyst will be needed. The PEG units help the molecule to have better solubility in aqueous solution. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

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).
The ExcelRT™ One-Step RT-qPCR kit (TaqMan, ROX) is designed for reverse transcription and quantitative real-time analysis of a specific target RNA by one-step reaction. The ExcelRT™ One-Step RT-qPCR kit (TaqMan, ROX), consisting of One-Step RT Enzyme Mix and 2X One-Step Master Mix, is a convenient kit designed for highly efficient cDNA synthesis and highly specific real-time PCR in a single tube. The One-Step RT Enzyme Mix contains a thermostable ExcelRT™ Reverse Transcriptase and a RNAok™ RNase inhibitor. Consequently, One-Step RT Enzyme Mix can reverse transcribe RNA to cDNA at a wide temperature range from 42 to 60°C and active against RNase A, RNase B and RNase C. By containing specialized hot-start Taq DNA polymerase, which greatly reduce primer-dimer formation and can be activated within 2 minutes, the 2X One-Step Master Mix features high specificity and is suitable for fast cycle program. This master mix includes ROX reference dye for normalization of each RT-qPCR assay.
Features
Reverse transcription at wide temperature range (42-60°C)
High specificity
Suitable for fast cycle program
With ROX reference dye
Storage
Aliquot to avoid multiple freeze-thaw cycles (stable within 30 freeze-thaw cycles)
Protect from light
-20°C for 12 months
