Mal-amido-PEG5-alkyne is a PEG linker containing a maleimide group and an alkyne. The hydrophilic PEG spacer increases solubility in aqueous media. The alkyne group can react with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Product Info
Overview
DNA can be isolated and detected from as little as 100 µL of sputum
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.

Principle
This product is based on the purification method of high binding magnetic particles. The sample is lysed and digested under the action of lysate and protease. DNA is released into the lysate. After adding magnetic particles and binding solution, DNA will be adsorbed on the surface of magnetic particles, and impurities such as proteins will be removed without adsorption. The adsorbed particles were washed with washing solution to remove proteins and impurities, washed with ethanol to remove salts, and finally DNA was eluted by elution buffer.
Advantages
Economy – less than 50% of the price of Qiagen and other imported products
Automatic – without labour

Storage and Stability
Proteinase K, Carrier RNA and MagPure Particles G should be stored at 2–8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15–25°C) does not affect their performance. Theremaining kit components can be stored dry at room temperature (15–25°C) and are stable for at least18 months under these conditions.The entire kit can be stored at 2–8°C, but in this case buffers should beredissolved before use. Make sure that all buffers are at room temperature when used.
