DBCO-NHCO-PEG4-acid is an analog of DBCO-Acid with a hydrophilic PEG spacer arm, which improves water solubility. This reagent is a non-activated building block with enhanced solubility in aqueous media and can thus be used to derivatize amine-containing molecule through a stable amide bond. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

The Permagen ring magnet low elution plate with integrated cushion base plate was designed for use in automation applications where volumes as low as 5 µL are required. Most PCR plates are bent, leading to inconsistent lab results. Unlike most products, we have added an angled frame around the top of our plate, this helps with two things, straightening out the PCR plate, and leading it to the proper location on the magnets during automation while the cushion assist compensates for labware inconsistencies.
SBS SLAS Footprint (127.75mm x 85.50mm) to fit into any automated liquid handling robot
Features include solid aluminum alloy construction and hard coat anodized finish for years of trouble-free use, and compatible with any magnetic beads
