Product Info
DBCO-C5-NHS ester is an amine-reactive compound, which can be used to modify an amine-containing molecule in organic media. This reagent isn’t soluble in aqueous media. The extended 5-carbon atom spacer arm improves solubility in commonly used organic solvents including dichloromethane, chloroform, THF, and ethyl acetate, and it also improves derivatization efficiency and stability of conjugates. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research use only.

N-(Acid-PEG2)-N-bis(PEG2-propargyl) is reactive with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The terminal carboxylic acid can react with primary amino groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Norgen’s Total Nucleic Acid Preservation Tubes are designed for ambient preservation and transport of total nucleic acids (DNA and RNA) from samples collected using a swab, including nasal, buccal, saliva, fecal, skin, surfaces, etc. The Total Nucleic Acid Preservation Tubes contain Norgen’s Total Nucleic Acid Preservative in a liquid format. The user simply collects the specimen using a sterile nylon flocked swab (not provided), and then transfers the swab into the Total Nucleic Acid Preservative. The 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 Total Nucleic Acid 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 Preservative allow DNA samples to be stored at room temperature for over 4 months and RNA samples to be stored at room temperature for over 2 months. Swab samples collected and preserved using Norgen’s Total Nucleic Acid Preservation Tubes are compatible with most commercially available DNA and RNA isolation methods. Samples stored in the tubes have been used successfully with most of Norgen Biotek’s DNA and RNA isolation kits and reagents, including Norgen’s Total RNA Purification Kit (Cat# 17200) and Norgen’s Saliva DNA Isolation Kit (Cat# RU45400). For purification of total nucleic acids please refer to the supplementary protocol provided with Norgen’s Total RNA Purification Kit (Cat#17200).
The Total Nucleic Acid Preservation Tubes can be stored at room temperature for up 1 year without any reduction in kit performance. The collect before date is indicated on the tube label and the kit box label.
