The kit includes HS Dye, HS Dilution Buffer, and two DNA Standards. The assay is accurate for DNA concentrations from 10 pg/µL to 100 ng/µL, and is highly selective for double-stranded DNA over RNA.
Features
Optimized condition for using with the Qubit® Fluorometer
Uses the Qubit® dsDNA High Sensitivity assay setting
Linear range: 0.2-100 ng dsDNA
Cuts costs by 60%
DNA selectivity and sensitivity of the HS kit. A series of input DNA (20, 40, 60, 80, 100, and 120 ng) was used with or without the contamination of RNA.
Comparison of dsDNA HS kits. The performance of the BioDynami dsDNA HS kit is nearly identical to that of Thermo Fisher’s Qubit dsDNA HS kit.

Product Info
Propargyl-PEG4-Maleimide has a propargyl group and a maleimide group. The propargyl group reacts with azide compounds or biomolecules under the catalyzation of copper in Click Chemistry reactions. The maleimide group enables the formation of a covalent bond with biomolecules containing a thiol group. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Norgen’s Fecal Swab Collection and Preservation System is designed for collection, ambient storage and transport of nucleic acids from stool specimens. The Fecal Swab Collection and Preservation System tubes contain Norgen’s Stool Preservative in a liquid format. The user simply collects the specimen using the provided swab, and then transfers the swab into the Stool Preservative. The Stool Preservative prevents the growth of Gram-negative and Gram-positive bacteria and fungi, and also inactivates viruses allowing the resulting non-infectious samples to be handled and shipped safely. In addition, the Stool Preservative eliminates the need to immediately process or freeze samples and allows the samples to be shipped to centralized testing facilities at ambient temperatures. The components of the Stool Preservative allow samples to be stored at room temperature for over 2 years for DNA and 7 days for RNA. To extend the stool RNA stability in the preservative, storage at -20°C or -70°C is recommended upon arrival at the testing facilities until RNA purification.
