Funcbeads™ Amino Magnetic Beads

The surface of Funcbeads™ Amino Magnetic Beads are modified with amino groups (NH₂), which can covalently couple bioligands such as polypeptides, proteins and oligonucleotides to the surface of magnetic microspheres under the action of special chemical agents (such as glutaraldehyde).

Funcbeads™ Amino Magnetic Beads are coupled to target proteins or antibodies in two ways:

• The carboxyl group (-COOH) on the protein/antibody is coupled by an amide bond.

• Amino groups (-NH2) on proteins/antibodies are coupled by glutaraldehyde (GA).

Specification

Funcbeads™ SA Magnetic Beads

Funcbeads™ SA Magnetic Beads couple streptavidin (SA) to the surface of magnetic beads through covalent bonds. The products can efficiently bind biotin-labeled antibodies, nucleic acids, proteins and other biological ligands, and can be used for the separation and detection of biotinylated nucleic acids, antibodies or other biotinylated ligands and target molecules. It is mainly used for immunodetection, immunoprecipitation, cell sorting, etc.

The schematic diagram of reaction principle is as follows:

Funcbeads™ Carboxyl Magnetic Beads

The surface of Funcbeads™ Carboxyl Magnetic Beads are modified with carboxyl groups (COOH), which can covalently couple bioligands such as polypeptides, proteins and oligonucleotides to the surface of magnetic beads through one-step or two-step activation under the activation of special chemical reagents (such as EDC, NHS).

The schematic diagram of reaction principle is as follows:
