Different-sized amplicons from 3 ng of a DNA plasmid were amplified. The use of Taq DNA polymerase resulted in clean and high yield of products, as analysed after PCR on a 0.8% agarose gel.
A fragment (64 bp) of the human blood-coagulation factor IIa (F2) was amplified from 20 ng, 2 ng, 200 pg and 20 pg of a human genomic DNA extract. The same experiment was performed in parallel using the Taq DNA polymerase mix from another well-established and known supplier. PCR products were subsequently analysed on a 2.5% agarose gel.
Non-specific amplification is prevented by using this Taq DNA polymerase variant as the DNA polymerase is hotstart-formulated. The 10x reaction buffer supplied together with the DNA polymerase has been specifically designed for optimal PCR performance and DNA polymerase activity. This allows the use of this DNA polymerase in a wide range of PCR applications.
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: (1) Saliva Collection Funnel and Collection Tube, (2) Collection Tube Cap, and (3) 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# Dx45400). 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 in vitro diagnostic use for medical purposes.
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.
Prior to saliva DNA isolation, vortex the Collection Tube containing preserved saliva for 10 seconds and incubate at 55°C for one hour. Saliva DNA can now be isolated from the preserved saliva samples using Norgen’s spin-column based Saliva DNA Isolation Kit Dx (Cat# Dx45400) or other commercially available methods that have been validated for use with Norgen’s Saliva DNA Collection and Preservation Devices.

The Residual DNA Sample Preparation Kit uses chemical lysis and magnetic beads to extract DNA from diverse sample types, including samples that contain high protein and low DNA concentration. The kit extracts residual genomic DNA from products that are produced in cell lines such as CHO, E. coli, E1A, HEK293, Vero, NS0 and Baculovirus. For quantification of residual DNA, we recommend using the resDNASEQ Residual DNA Quantitation kit as described in the resDNASEQ Residual DNA Quantitation kit User Guide. To ensure accurate quantitative results, each sample in triplicate and perform a single PCR reaction for each extraction.
