Abvigen provides customized Custom Magnetic Particles Conjugation services to customers, using various types of Magnetic Particles to form strong bonds with antibodies, proteins, or other biomolecules.
Abvigen can provide the following methods for attaching biological ligands to Magnetic Particles: NHS-EDC method and Biotin-Streptomycin method. The NHS-EDC method utilizes EDC and NHS reagents to activate the surface of Magnetic Particles and bind to proteins. This method has the advantages of mild reaction conditions, good biocompatibility, minimal impact on biomolecules, and relatively single products. This method has strong controllability and can effectively reduce the impact of steric hindrance on the structure of conjugated proteins. The Biotin-Streptomycin method utilizes magnetic particles modified on the surface of streptomycin to bind with biotinylated proteins. This method has a tight binding and can withstand the effects of extreme pH values, temperatures, organic solvents, and denaturing agents. The product has good stability.
EDC-NHS Method
1. EDC and NHS are added to the buffer solution in proportion to prepare the EDC-NHS active solution, adjust the pH value, add disperse the Magnetic Particles, and activate the surface of the Magnetic Particles. ?
2. Mix the biomacromolecules to be coupled (such as proteins, peptides, etc.) with EDC-NHS active solution in a certain proportion, and let them stand for a certain period of time for crosslinking reaction.
3. Clean and purify the product to remove unreacted impurities such as EDC and NHS. Ensure the purity of the product. ?
4. Analyze products to ensure compliance with customer requirements ??
Biotin-Streptomycin method
1. Combine the protein to be conjugated with biotin to obtain biotinylated protein
2. Magnetic Particles modified with streptomycin bind to biotinylated proteins
3. Clean and purify the reaction product to remove impurities
4. Analyze products to ensure compliance with customer requirements
