DBCO-PEG5-acid is an analog of DBCO-Acid with PEG linker and a DBCO group. DBCO group is a highly reactive cycloalkyne which is commonly used for copper-free Click Chemistry reactions. The hydrophilic PEG chain allows for increased water solubility of compounds in aqueous media. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. Reagent grade, for research purpose.

The oasig freeze drying process stabilises all of the active components allowing these reagents to be shipped and stored at room temperature. This hugely simplifies the logistics of purchasing, shipping and using the technology. Whether you are in a sophisticated laboratory in Texas or a mobile field hospital in Timbuktu we can supply complete qPCR kit and reagent packages to your door quickly and cheaply via standard shipping methods without the need for dry ice or a cold chain of any sort.
The performance of the reagents is second to none. We are confident that you will find excellent data quality and even see an improvement in data quality versus many traditional frozen master mixes.
No cold shipping required. Our unique, oasig Lyophilised qPCR Master Mix in a 150 reaction pack. Perfect to accompany any genesig kit for a DNA target.
Primerdesign real-time PCR reagents are manufactured to the highest standards within our ISO9001:2008 and ISO13485:2012 certified quality management laboratory environment.
