Norgen’s Saliva Exosome Collection and Preservation Kit is an all-in-one solution designed for 1) simple and non-invasive saliva collection; 2) preservation of exosomes in saliva samples at ambient temperature; and 3) isolation of high quality intact exosomes and exosomal RNA within a laboratory setting. The Saliva Exosome Collection, Preservation and Isolation Kit contains 50 Individual Saliva Exosome Collection and Preservation Devices. Each of the 50 individual Saliva Exosome Collection and Preservation Devices consists of 3 components:
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, the Collection Tube is securely capped with Collection Tube Cap. The collected saliva is mixed by gentle inversion for several times till the saliva colour changes into yellow. The Saliva Collection Tube is subsequently sent to the laboratory for the purification of intact exosomes and for the subsequent isolation and analysis of saliva exosomal RNA. The saliva exosomes in preserved samples are stable for 2 years at room temperature.

This product allows rapid and reliable isolation of high-quality genomic DNA from various soil and stool samples. Up to 100mg stool sample and 500 mg soil samples can be processed in 60 minute. The system combines the reversible nucleic acid binding properties of HiPure matrix with the speed and versatility of spin column technology to eliminate PCR inhibiting compounds such as humic acid from soil samples. Purified DNA is suitable for PCR, restriction digestion, and next-generation sequencing. There are no organic extractions thus reducing plastic waste and hands-on time to allow multiple samples to be processed inparallel.

Soil/Stool sample is homogenized and then treated in a specially formulated buffer containing detergent to lyse bacteria, yeast, and fungal samples. Humic acid, proteins, polysaccharides, and other contaminants are removed using our proprietary Absorber Solution. Binding conditions are then adjusted and the sample is applied to a DNA Mini Column. Two rapid wash steps remove trace contaminants and pure DNA is eluted in low ionic strength buffer. Purified DNA can be directly used in downstream applications without the need for further purification.

Storage and Stability
Absorber Solution should be stored at 2-8°C upon arrival. However, short-term storage (up to 24 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored dry at room temperature (15-25°C) and are stable for at least 18 months under these conditions.

t-Boc-N-Amido-PEG7-propargyl is a crosslinking reagent that enables the formation of triazole linkage with azides under the catalyzation of copper. The Boc-protected amine can be deprotected under mild acidic conditions. By introducing PEG chain into the molecule, the hydrophilicity can be greatly improved. Reagent grade, for research purpose.
