Norgen’s Stool Nucleic Acid Collection and Preservation Devices Dx are designed for the collection and preservation of nucleic acids from fresh stool specimens. The Stool Nucleic Acid Collection and Preservation Devices Dx – 50 contains 50 individual Stool Nucleic Acid Collection and Preservation Devices Dx. Each Stool Nucleic Acid Collection and Preservation Device Dx consists of Norgen’s Stool Nucleic Acid Collection and Preservation Tube Dx containing Norgen’s Stool Preservative in a liquid format. The user simply collects stool into the tubes (fill up to the line indicated on the tube) and mixes gently until the stool is well submerged under the preservative. The Stool Nucleic Acid Collection and Preservation Tube Dx is subsequently sent to the laboratory for DNA and/or RNA isolation and analysis. The stool DNA in preserved samples is stable for more than 2 years at room temperature, and the stool RNA in preserved samples is stable for 7 days at room temperature. DNA can be isolated from the preserved stool samples using Norgen’s Stool DNA Isolation Kit Dx (Cat. Dx27600) and RNA can be isolated from the preserved stool samples using Norgen’s Stool Total RNA Purification Kit Dx (Cat. Dx49500). These tubes are ideal for collecting and preserving DNA and RNA samples for in vitro diagnostic use for medical purposes.
NOTE: This product is not available for sale in the United States.

Disulfide Biotin alkyne is an azide-activated cleavable biotin probe that allows for efficient recovery of avidin-bound protein complexes in affinity-based assays. This reagent contains a biotin moiety linked to an alkyne group through a spacer arm containing a cleavable disulfide linker. Under reducing conditions (50 mM dithiothreitol, 10 mM 2-mercaptoethanol or 1% sodium borohydride), the disulfide bonds are cleaved, releasing the biotin tag and any avidin conjugate bound to it.
