Mal-amido-PEG4-alkyne is a short PEG linker featuring a maleimide and a terminal alkyne. Maleimide is a covalent ligand used for linking thiols such as those in cysteines residues in proteins, while terminal alkynes can be used in copper (I) click chemistry with azides on target molecules.

Peelable heat sealing film which is optically clear. Seal is suitable for qPCR and optical applications.
Norgen’s Total Nucleic Acid Preservation Tubes Dx are designed for ambient preservation and transport of total nucleic acids (DNA and RNA) from samples collected using a swab. 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. This kit is ideal for collecting and preserving nasal and oral swab samples for in vitro diagnostic use for medical purposes. This kit can be used to preserve viral RNA, including SARs-CoV-2 RNA for detection of COVID-19.
Norgen’s Total Nucleic Acid Preservation Tubes Dx are intended for use by professional users such as technicians, physicians and biologists experienced and trained in molecular biological techniques.
Norgen’s Total Nucleic Acid Preservation Tubes Dx do not provide a diagnostic result. It is the sole responsibility of the user to use and validate these devices in conjunction with a downstream in vitro diagnostic assay.
