Propargyl-PEG14-acid

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.

Overview

• Isolate high quality DNA from a broad variety of phage strains
• High yields of total DNA
• Fast and easy processing using a rapid spin-column format
• No phenol or chloroform extractions or cesium chloride banding required
• High yields of DNA recovered 3-15 µg DNA from 10⁶-10¹⁰ pfu/ mL of enriched phages

This kit provides a rapid spin column method for the purification of total DNA from a broad spectrum of bacteriophages propagated in bacteria grown in liquid cultures. The DNA is isolated without the use of phenol, chloroform or cesium chloride banding procedures. The spin-column based procedure is rapid and can be completed in less than 45 minutes. The kit is highly efficient for processing small volumes of phage supernatant (500 µL – 1 mL) and with the optional DNase and Proteinase K treatments phage DNA yields are maximized while host DNA contamination is minimized. Purified total phage DNA is of the highest integrity, and can be used in a number of downstream applications including PCR, qPCR, Restriction Fragment Length Polymorphism (RFLP), sequencing, cloning, Southern Blot and more.

The Ethanol (Liquid Ready) assay kit is a rapid (~5 min), method for the specific measurement and analysis of ethanol in wine, beverages, foodstuffs and other materials. Supplied as a “ready to use” liquid stable formulation that is suitable for manual auto-analyser and microplate formats and is simple, reliable and accurate.

Suitable for manual, auto-analyser and microplate formats.

Note for Content: The number of manual tests per kit can be doubled if all volumes are halved.  This can be readily accommodated using the MegaQuant^TM  Wave Spectrophotometer (D-MQWAVE).
