OGR-575
For assisted collection
Collect superior samples for your genetic analysis
Are you looking for a non-invasive way to collect DNA from patients that cannot or choose not to comply with blood collections? DNA Genotek has developed a product for collecting high quantity and high quality DNA from saliva using absorbent sponges. This method is an all-in-one system for the collection, stabilization and transportation of DNA from saliva.

PD-WP-00031: Impact of population and laboratory methods on DNA yield and variability
Summary of the total DNA yield from Oragene/saliva samples as reported in peer-reviewed publications.
PD-WP-011: Human genomic vs bacterial DNA content of Oragene/saliva samples
Quantitative information about the amount of human genomic and bacterial DNA in Oragene/saliva samples, as estimated by two different methods.
MK-AN-017: Tips to improve the A260/A280 ratio of Oragene-purified DNA samples
Despite the fact that sample turbidity (i.e., absorbance at A320) does not affect down-stream analysis, some users have enquired about modifications to our standard protocol that will improve this ratio. In this document, we describe 3 alternative methods that can be used to obtain high A260/A280 ratios from all samples.

PD-PR-075: DNA quantification of Oragene/saliva samples
Protocol to quantify purified total dsDNA by fluorescence (specific for double-stranded (ds) DNA). Measurement of absorbance at 260 nm (A260) is commonly used for quantifying DNA. Disadvantages of using A260 include (i) insensitivity of the assay, and (ii) interference by non-DNA components such as RNA.
MK-AN-017: From turbidity to clarity: Simple methods to improve the A260/A280 ratio of Oragene-purified DNA samples
Despite the fact that sample turbidity (i.e., absorbance at A320) does not affect down-stream analysis, some users have enquired about modifications to our standard protocol that will improve this ratio. In this document, we describe 3 alternative methods that can be used to obtain high A260/A280 ratios from all samples.
PD-PR-040: RNA removal within Oragene/saliva samples
This protocol describes the use of double-RNase digestion to remove the RNA in Oragene/saliva samples.
PD-PR-065: Bacterial DNA assay
The purpose of this assay is to determine the bacterial DNA content of purified DNA from Oragene/saliva samples.
PD-WP-00030: Dye-free quantification of Oragene/saliva DNA extracts using the Trinean DropSense96® droplet reader and cDrop™ spectral analysis software
The purpose of this application note is to evaluate the Trinean method with a cDrop protocol specific for DNA extracted from Oragene/saliva samples using prepIT•L2P.

This is a truly great product. I have tried many different chemistries to obtain DNA… and I have not seen a better compromise for yield, purity, time to extract and ease of collection than Oragene.
