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.

BEST WHOLE BODY MOISTURIZER HANDS DOWN
Size: 16 Fl Oz (Pack of 1)
This is the best shea butter, whipped whole body moisturizer on the planet in my opinion. It is so thick, rich and creamy and melts into your skin. Your skin drinks this stuff in. You don't even need to rub it in but I do. It's ian incredibly thick creaminess but not like Vaseline products, it's NOT GREASY!! It's lightly scented yet doesn't irritate my super sensitive skin. My skin gets so dry and tight that it hurts when I move. Particularly when laying in bed right after my hot bath. I use this moisturizer and my skin feels immediate relief. Keeps my skin soft, smooth and radiant Absolutely LOVE LOVE Nivea!!

Soft, smooth glowing 61 year old skin!!
Size: 16 Fl Oz (Pack of 1)
I love the Nivea brand and this product is excellent. It makes my 61 year old skin smooth, soft and glowy. Absorbs fast and is very moisturizing. Giant tub for the money

high fragrance
Size: 16 Fl Oz (Pack of 1)
This isn't my favorite Nivea product. If you're looking for the same consistency as the blue tub, this isn't it. The fragrance is a bit strong for me, but it does moisturize well and does not leave you feeling heavy or greasy. I will keep using it until it is gone but not repurchase.
