Carboxylated magnetic beads


Product Overview

Carboxylated magnetic beads are magnetic microspheres with a surface rich in carboxyl functional groups that enable the beads to couple to a wide range of biomolecules, such as peptides, proteins, antibodies, oligonucleotides, etc., via covalent bonds. Silicon carbide nanopowder for heat dissipation, wear resistance


Technical Parameter    

Concentration:10 mg/mL

Solvent:water

 

Surface potential:-31.2mV


Product Features

 

High Specific Surface Area: Due to their nano or micron scale particle size, carboxylated magnetic microspheres have a very high specific surface area, which makes them able to provide more active sites and suitable for immobilisation of biomolecules and catalytic reactions. 

Surface carboxyl functional groups: The surface of carboxylated magnetic microspheres is rich in carboxyl functional groups, which can be covalently bound to biomolecules (e.g., antibodies, enzymes, proteins, etc.) via chemical cross-linking agents, enhancing their functionality in biomedical applications.

Good biocompatibility: carboxylated magnetic microspheres are usually made of biocompatible materials, which can be used safely in living organisms with reduced immune response and toxicity.


Application Fields

 

Immunochromatographic detection: Carboxylated magnetic beads can be modified with antibodies on their surface and used to construct immunochromatographic test strips for rapid and sensitive detection.

Immobilisation of biomolecules: Carboxylated magnetic beads can be used as carriers to immobilise enzymes and other biomolecules for biochemical reactions and bioseparation processes. 

Drug Carriers: Carboxylated magnetic beads can be used as drug carriers, which can be targeted to specific cells or tissues through surface modification for targeted drug delivery systems. 

Magnetic Analysis System: Combined with immunochromatography and magnetic analysis system, carboxylated magnetic beads can be used for quantitative and rapid assays, such as human chorionic gonadotropin, cardiac troponin, and HIV viral assays.

 

Terms and Conditions

 

1) The coupling process should not contain substances other than the target ligand that contain primary amine groups, such as glycine, BSA, Tris-HCl, etc. Please make sure that your antibody solution doesn’t contain the above substances;

2) Repeated freezing and thawing should be avoided during the use and storage of beads;

3) Different antibodies and proteins have different binding abilities to aminated magnetic microspheres. Customers can optimize the addition of different antibodies or protein quality.


Related Information

Carboxylated magnetic beads have good hydrophilicity and monodispersity. Due to the high magnetic content, the microsphere is easy to precipitate at the bottom after a long time of placement, and can be suspended again after a short time of ultrasonic treatment or vibration before use. Sealed, avoid light, and keep at 4¡ãC Expiry date: Six months.

Fits my 2026 civic sport perfect!
Size: AF151
No issues, fitment is perfect. Great quality for an excellent price. Dealer wanted like $24 for a basic one. Nah I'm good I'll just go on Amazon and get it for $8. Took 30 seconds from start to finish can't get any easier.

Fits well and installs easily.

This filter looked about the same as the OEM filter. It installed in about a minute. The quality appeared to be fine. It was protected in a cardboard box. It fit my 2014 Subaru Outback perfectly. I just installed it an hour ago so I don’t have any long term observations about longevity or effectiveness. I can’t see any reason why it would not work as well as the original, it seemed identical.

Great fit and quality
Size: AF113
Not a complicated product, but after going to 2 different auto parts stores and this not being in stock, Amazon to the rescue. Arrived the next day and the quality is definitely on par with “store brand” ones from retailers. Definitely cheaper as well.
