Product Info
DBCO-PEG12-acid is an analog of DBCO-Acid with hydrophilic PEG linker and a DBCO group. The DBCO groups is commonly used for Click Chemistry reactions. The hydrophilic PEG chain allows for increased water solubility of compounds in aqueous media. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Propargyl-PEG5-amine is a propargyl linker that is commonly used as a Click Chemistry reagent for copper-catalyzed reactions with azides. The amine moiety reacts with carboxylic acids, activated NHS esters and other carbonyl compounds. The PEG spacer helps improve the water solubility of the molecule in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Principle and Interpretation
Tryptone, proteose peptone, meat extract, yeast paste powder provide nitrogen sources, vitamins, amino acids, and growth factors; sodium chloride can maintain a balanced osmotic pressure; sodium dihydrogen phosphate and potassium dihydrogen phosphate as buffering agents; aesculin are fermentable sugars; lithium chloride and other antibiotics can inhibit Gram negative bacteria and most Gram positive bacteria.
