dPEG® Compounds from Quanta Biodesign

These are dPEG® compounds from Quanta Biodesign that contain discrete length PEGs. This can improve reproducibility in experiments when compared to using PEGs of variable length. PEGS have high aqueous solubility and a substances aqueous solubility can be improved by attaching a PEG. Some of these compounds contain a single reactive end for attachment to proteins such as through amines or sulfhydryls. This list includes branched PEGs which are more compact than long linear PEGs. There are also compounds with two reactive ends for crosslinking. Some of the compounds have azide groups which can be attached to alkynes using copper click chemistry or to strained alkynes through copper-free click chemistry. Some of the compounds have a biotin on one end for capture by avidins. Overall the many options offered by these dPEG® products can enable a variety of biconjugation applications.
