t-Boc-N-amido-PEG4-Amide-Tri-(propargyl-PEG10-ethoxymethyl)-methane is a branched crosslinker molecule with three terminal propargyl groups and a t-Boc protected amide group. The propargyl groups can react with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The protected amine can be deprotected under acidic conditions. Reagent grade, for research use only.

The Cylindrospermopsin plate kit is a competitive enzyme-labeled immunoassay. The Cylindrospermopsin sample extract and calibrators are pipetted into the test wells followed by the Cylindrospermopsin antibody into the test wells to initiate the reaction. During the 30 minutes incubation period, Cylin-drospermopsin from the sample and Cylindrospermopsin antigen compete for binding to the Cylindrosper-mopsin antibody. The Cylindrospermopsin antibody is captured on the walls of the test well. Following this 30-minute incubation, the contents of the wells are removed and the wells are washed to remove any unbound Cylindrospermopsin and free Cylindrospermopsin antibody. After wash, 1X HRP-conjugated Antibody#2 is added for 30 minutes incubation. The wells are washed afterwards, and a clear substrate is then added to the wells and any bound enzyme conjugate causes the conversion to a blue color. Following a 15-minute incubation, the reaction is stopped and the amount of color in each well is read. The color of the unknown samples is compared to the color of the calibrators and the Cylindrospermopsin concentration of the samples is derived.

endo-BCN-PEG4-t-butyl ester is a click chemistry linker containing a BCN group and a t-butyl protected carboxyl group. 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. The t-butyl ester can be converted to free acid under acidc condition. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

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%.

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).
