Photocleavable DBCO-NHS ester reagent contains an amine reactive group linked to DBCO moiety through a spacer arm containing a photocleavable moiety. Molecules jointed by the copper-free click reaction can be efficiently photoreleased, typically >90% in 5-25 minutes using an inexpensive, near-UV, low intensity lamp (e.g. 365 nm lamp at 1-5 mW/cm2). 名称: DBCO-C6-NHS Ester   MW:430.45 英文介绍： An activated ester with extended 6-carbon atom long spacer. DBCO-NHS Ester reacts with primary amines (e.g., side chain of lysine residues or aminosilane-coated surfaces) at pH 7-9 to form covalent bonds. Extended 6-carbon spacer arm is beneficial for some application. This reagent has limited shelf life; however, corresponding acid and its derivatives are found to be stable over long period of time.

DBCO-Sulfo-NHS-Ester enables simple and efficient labeling of antibodies, proteins and any other primary amine-containing macromolecules with DBCO moiety. This reagent is water-soluble, enabling labeling to be performed in the absence of organic solvents such as DMSO or DMF for applications that cannot tolerate solvents or are complicated by their inclusion. Specific labeling of cell surface proteins is another common application for these uniquely water-soluble and membrane impermeable reagents. 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 overcoming 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-C6-Acid   MW:333.83 英文简介： An analog of DBCO-Acid with improved stability and solubility in commonly used organic solvents. DBCO reagents, also known as ADIBO or DIBAC are routinely used building blocks for synthesis of complex molecules to be used in Cu-free ligation applications. Using DBCO-C6-Acid primary or secondary amines can be easily functionalized with DBCO moiety in the presence of activators (e.g. EDC, or HATU) through a stable amide bond. A longer carbon spacer arm improves stability and solubility of this reagent in commonly used organic solvents. 名称：DBCO-PEG5-Acid    MW:596.67 英文简介： An amine-reactive building block with enhanced stability and solubility in aqueous 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 compared 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 complementary azido-modified molecules. 名称：DBCO-PEG4-Acid  MW:552.62 英文简介： An amine-reactive building block with enhanced solubility in aqueous media. DBCO-PEG4-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 compared to reagents having only hydrocarbon spacers 名称：DBCO-PEG4-4-Formylbenzoate    MW:655.77 英文简介： A heterobifunctional reagent for labeling aminooxy-containing compounds. DBCO-PEG4-4-Formylbenzoate reacts specifically and efficiently with an aminooxy group at pH 4-5 to form a covalent oxime bond. The oxime ligation with aromatic aldehydes is highly chemoselective and is compatible with other functional groups present in peptides or biomolecules. An aniline catalysis can be used to activate aromatic aldehyde towards an aminooxy group and greatly enhance the rate of ligation reaction. 名称：ThioLinker-DBCO 英文简介： A unique, water-soluble, bis-alkylating reagent that allows for site-specific labeling of antibodies under mild aqueous conditions. The traditional sulfhydryl labeling chemistry cleaves disulfide bridges and leaves them in “open form”, which may compromise the stability and function of an antibody or other proteins. ThioLinkerTM-DCBO re-bridges the disulfide bond, and enhances the structural stability of the protein. In addition, conjugates prepared with ThioLinkerTM reagents benefits from reduced heterogeneity and better stability. 名称：DBCO-Maleimide  MW:427.75 英文简介： A short-length, sulfhydryl-reactive labeling reagent that contains a short hydrocarbon spacer. DBCO-Maleimide enables simple and efficient incorporation of DBCO moiety onto cysteine-containing peptides or other thiol-containing molecules. The maleimide group specifically and efficiently reacts with reduced thiols (sulfhydryl groups, –SH) at pH 6.5 to 7.5 to form stable thioether bonds. A short spacer arm adds minimal mass to modified molecules (427.4 daltons). 名称：DBCO-PEG4-Maleimide  MW:674.74 英文简介： A mid-length, sulfhydryl-reactive labeling reagent with enhanced water solubility provided by a PEG4 spacer. DBCO-PEG4-Maleimide enables simple and efficient incorporation of DBCO moiety onto antibodies, cysteine-containing peptides and other thiol-containing molecules. The hydrophilic polyethylene glycol (PEG) spacer arm imparts water solubility that is transferred to the labeled molecule, thus reducing aggregation of labeled proteins stored in the solution.
