DBCO STP ester is a water-soluble reagent with a terminal DBCO group and a STP ester group. DBCO STP ester that can be used for the modification of peptides, antibodies, proteins, and other molecules containing the amine group. The STP esters are excellent alternatives to conventional N-hydroxysuccinimide (NHS) esters for coupling reactions in aqueous environments. The DBCO groups is commonly used for copper-free Click Chemistry reactions due to its strain promoted high energy. Reagent grade, for research use only.

High quality DNA is suitable for sensitive downstream applications including PCR, qPCR, sequencing, SNP analysis, microarrays, RFLP and Southern Blot Analysis
Norgen’s Saliva DNA Collection and Preservation Devices are designed for 1) simple and non-invasive saliva collection and 2) preservation of DNA in saliva samples at ambient temperature. Each of the 50 Saliva DNA Collection and Preservation Devices consists of 3 components:
Saliva Collection Funnel and Collection Tube
Collection Tube Cap
Norgen’s Saliva DNA Preservative contained within a sealed squeezable ampoule
Saliva samples are collected by spitting inside the Collection Funnel which has been assembled with the Collection Tube. After collecting the required volume of saliva the Collection Funnel is removed and the contents of the Preservative Ampoule are then added and mixed with the collected saliva. The Saliva Collection Tube is subsequently sent to the laboratory for DNA isolation and analysis. DNA can be isolated from the preserved saliva samples using Norgen’s Saliva DNA Isolation Kit (Cat. RU45400). Each of Norgen’s Collection Tubes is labeled with a unique serial number that can be used for secure and anonymous tracking of the sample. The saliva DNA in preserved samples is stable for more than 2 years at room temperature. This kit is ideal for collecting and preserving DNA samples for epidemiological and population studies.
Saliva DNA Preservative
Norgen’s Saliva DNA Preservative is an aqueous storage buffer designed for rapid cellular lysis and subsequent preservation of DNA from fresh specimens. The buffer 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 buffer eliminates the need to immediately process or freeze samples and allows the samples to be shipped to centralized testing facilities at ambient temperature. The components of the buffer allow samples to be stored for more than 2 years without any detectable DNA degradation.
When stored at room temperature, unused Norgen Saliva Preservative Tubes are stable through to the collect-before date without any reduction in performance. Please see the device insert or tube label for collect-before date.
Once collected, saliva is stable for more than 2 years when kept tightly sealed and stored at room temperature.
The Collection Tube, the Collection Funnel and the Device Container of each Individual Saliva DNA Collection and Preservation Device are recyclable.

Isolate high quality mitochondrial DNA
Recovered DNA is compatible with various downstream applications
Over the past several decades, mitochondrial DNA (mtDNA) has played an increasingly important role in forensic analyses of various criminal cases. A few hairs left at a crime scene contain enough mtDNA for extraction. The hair shaft, which protrudes out of the scalp, does not contain any nuclear DNA. It does, however, contain mtDNA. While nuclear DNA is present in only two copies per cell, the small circular mtDNA molecule is present in hundreds to thousands of copies per cell making it very abundant. Mitochondrial DNA is maternally inherited, and all of a woman’s offspring will have the same mtDNA profile. An advantage of this is that a single maternal relative of that person may provide a reference sample for comparison to a sample found at a crime scene.
Norgen’s Hair Mitochondrial DNA Isolation Kit provides a fast, reliable, and simple procedure for isolating mtDNA from hair shafts. Purification is based on spin column chromatography and the DNA is preferentially purified from other components. Typical yields will vary depending on the sample input volume used. The purified DNA is compatible with all downstream applications including PCR and NGS.
Storage Conditions and Product Stability Store DTT at -20°C upon arrival. All other solutions should be kept tightly sealed and stored at room temperature. These reagents should remain stable for at least 1 year in their unopened containers. The kit contains a ready to-use Proteinase K solution, which is dissolved in a specially prepared storage buffer. The Proteinase K is stable for up to 2 years after delivery when stored at room temperature. To prolong the lifetime of Proteinase K, storage at 2–8°C is recommended.
