Product Name

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.

Good quality
This product is very good. It smells weird but it’s not bad. It works, I applied it once and got a bit darker. About the packaging it could’ve been handled better, one of the bottles spilled a little bit and it was everywhere

My favorite moisturizer with SPF
Color: Untinted (1.7 oz)
Great mineral sunblock. One of the few mineral sunblocks that is easy to rub in so you don't look like Caspar the ghost after you apply it. Great natural ingredients. My only wish is for Clean + Kind top also make their daily moisturizer with SPF in a stick

Pretty good
Color: Tinted (1.7 oz)
This tinted spf checks a lot of boxes for me, but the smell when you initially put it on isn’t good.. (but then it goes away). I like that’s it’s not too matte and not too oily.

Unicorn sunscreen
Color: Tinted (1.7 oz)
I've used at least three bottles of both the body and face sunscreens by this line. It's honestly a unicorn sunscreen. Actually clean ingredients, over 18% zinc oxide, which apparently is the minimum needed to actually combat harmful rays, affordable, actually sinks into the skin and doesn't leave a white cast, AND my kids don't complain when I apply it to them. I use very high-end facial products and I've added this very affordable sunscreen to my daily routine and have been extremely impressed. Highly recommend and I'm so glad I found it.
