DBCO聚乙二醇修飾一些產品：

DBCO PEG是一類用于無銅點擊化學的標記試劑。PEG鏈增加了親水性，并細化了聚乙二醇化部分的性質。

DBCO PEG is a class of labeling reagents used in Cu-free click chemistry. The PEG chain increases the hydrophilicity and fine-tunes the properties of the PEGylated moiety.

具體產品介紹和結構式：

名稱：DBCO-PEG5-NHS Ester  MW:693.74
英文簡介：
An amine-reactive labeling reagent with enhanced water stability and solubility.
DBCO-PEG5-NHS Ester reacts specifically and efficiently with a primary amine (e.g., side chain of lysine residues or aminosilane-coated surfaces) at pH 7-9 to form a covalent bond. 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 solution. The PEG spacer arm provides a long and flexible connection that minimizes steric hindrance involved with ligation to complementary azide-containing molecules.

 
名稱：DBCO-PEG4-NHS Ester  MW:649.68
英文簡介：
An amine-reactive labeling reagent with enhanced water solubility provided by a PEG4 spacer.
DBCO-PEG4-NHS Ester reacts specifically and efficiently with a primary amine (e.g., side chain of lysine residues or aminosilane-coated surfaces) at pH 7-9 to form a covalent bond. 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 solution. The PEG spacer arm provides a long and flexible connection that minimizes steric hindrance involved with ligation to complementary azide-containing molecules.

結構式

名稱：DBCO-PEG5-Acid    MW:596.67
英文簡介：
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.
 

名稱：DBCO-PEG4-Acid  MW:552.62
英文簡介：
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

名稱：DBCO-PEG4-Maleimide  MW:674.74
英文簡介：
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. The PEG spacer arm provides a long and flexible connection that minimizes steric hindrance involved with ligation to complementary azide-containing molecules.

名稱：DBCO-PEG4-Biotin
英文簡介：
An azide-reactive biotinylation reagent with an extended PEG4 spacer arm.
DBCO reacts with an azide to produce a stable triazole, also referred to as the Cu(I)‐free or strain-promoted click reaction. The azide group, which is the reactive target of DBCO-activated biotin, can be introduced into proteins or other cellular targets via azide labeling reagents or through in vivo labeling with azide-derivatives of naturally occurring metabolic building blocks. This reaction possesses extreme selectivity and biocompatibility, such that the complimentary reagents can form covalent bonds within richly functionalized biological systems, and, in some cases, living organisms.
