Carboxyl Quantum Dots are a group of water soluble core/shell quantum dots with reactive group of carboxylic acid, which allows covalent amide bond formation to antibodies, proteins, peptides or other biomolecules via primary amine (NH2) groups. Their surface is specifically engineered with a polymer coating for high binding capacity and low non-specific binding. Carboxyl Quantum Dots are very stable in most buffer solutions in the pH range of 5-10.

Ocean NanoTech’s carboxyl-terminated quantum dots, ranging from 425-665nm, are now available in an easy-to-use kit format, allowing researchers to conjugate proteins & ligands of their own choice. The kit contains Carboxyl Quantum Dots and reagents sufficient for performing four (4) conjugation reactions . Briefly, the QDs are activated using carbodiimide and N-hydroxysuccinimide followed by conjugation to amino groups that are present on the target protein/ligand such as bovine serum albumin, streptavidin and immunoglobulin.
