DBCO-PEG5-Acid试剂简介：

应用介绍：DBCO-PEG5-Acid,DBCO-PEG5-COOH,二苯基环辛炔聚乙二醇-羧酸

An amine-reactive building block with enhanced stability and solubility in aueous media.
DBCO-PEG5-Acid is a polyethylene glycol-containing reagent with terminal carboxylic acid (–COOH) that can be reacted with primary or secondary amine groups in the presence activators (e.g. EDC) forming a stable amide bond. The PEG spacer arm is hydrophilic and provides greater solubility to labeled molecules pared to reagents having only hydrocarbon spacers. The PEG spacer arm also gives the reagent a long and flexible connection to minimize steric hindrance involved with reacting with plementary azido-modified molecules.

名称：DBCO-Acid   MW:305.11
英文简介：
DBCO-Acid is an amine reactive, non-activated cyclooctyne building block.
The use of strained cyclooctynes instead of terminal alkynes allows for overing a major drawback of copper-catalyzed azide-alkyne cycloaddition (CuAAC) - the need for the toxic copper catalyst. The ring strain in cyclooctynes, such as DBCO-Acid makes them highly reactive in the cycloaddition reaction. This reaction was termed as the strain-promoted alkyne-azide cycloaddition (SPAAC) or copper-free click reaction and has been widely used for bioconjugation and for labeling living cells and living animals.

名称：DBCO-PEG4-Desthiobiotin
英文简介：
An azide-reactive desthiobiotin reagent that allows easy elution from streptavidin.
Desthiobiotin is a single-ring, sulfur-free analog of biotin that binds to streptavidin with nearly eual specificity but less affinity than biotin (Kd = 1011 vs. 1015M, respectively). Conseuently, desthiobiotinylated proteins can be eluted readily and specifically from streptavidin affinity resin using mild conditions based on petitive displacement with free biotin. For pull-down experiments with biological samples, this soft-release characteristic of desthiobiotin also helps to minimize co-purification of endogenous biotinylated molecules, which remain bound to streptavidin upon elution of the target protein plexes with free biotin.
