Sputum Liquification Buffer (Cat. 28289) can be purchased separately
This kit constitutes an all-in-one system for the rapid isolation of DNA from sputum samples. It allows for the isolation of bacterial or eukaryotic DNA from the sputum samples using spin-column chromatography based on Norgen’s proprietary resin. The kit includes all the reagents needed to process sputum DNA. The protocol can be completed in 30 minutes. Purified DNA is of the highest quality and free from inhibitors, and can be used in sensitive downstream applications including PCR and qPCR.
Background
A sputum specimen is the name given to the mucus which is expectorated from the lower airways. High quality sputum samples should contain very little saliva, as this may contaminate the sputum sample with oral bacteria. Sputum samples are typically evaluated to look for infections such as Moraxella catarrhalis, Mycobacterium tuberculosis, Streptococcus pneumoniae ;and Haemophilus influenza. Other pathogens can be detected in sputum as well, including HIV. In addition, sputum samples are useful in the detection of lung cancer or to evaluate chronic inflammation.
* Average DNA yield will vary depending on the health status of the donor
Storage Conditions and Product Stability All solutions should be kept tightly sealed and stored at room temperature. This kit is stable for 2 years after the date of shipment.
Norgen’s Sputum DNA Isolation Kit contains ready-to-use Proteinase K, which is dissolved in a specially prepared storage buffer. The buffered Proteinase K is stable for up to 2 years after the date of shipment when stored at room temperature.
For the isolation of Listeria spp. from food and environmental specimens.
Principle and Interpretation
Tryptone, proteose peptone, meat extract, yeast paste powder provide nitrogen sources, vitamins, amino acids, and growth factors; sodium chloride can maintain a balanced osmotic pressure; sodium dihydrogen phosphate and potassium dihydrogen phosphate as buffering agents; aesculin are fermentable sugars; lithium chloride and other antibiotics can inhibit Gram negative bacteria and most Gram positive bacteria.

endo-BCN-PEG2-PFP ester is a click chemistry active ester. The PFP esters have similar applications as the NHS esters, but are more stable in aqueous solution. They can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The BCN group can react with azide-tagged biomolecules. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
