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.

Long lasting dog treat
Flavor Name: Bacon, Size: 1 Count (Pack of 1)
My dog absolutely loved this stuffed shin bone—it kept her occupied way longer than most treats, which is always a win. It’s a great option when you need something that will actually hold their attention. What I Loved:    •   Long-lasting chew compared to typical treats    •   The stuffing inside keeps dogs interested and engaged    •   Helps with boredom and keeps them busy    •   Once finished, the bone can be reused with other fillings One Small Con:    •   It can get a little messy depending on how your dog chews, so it’s best to give it in an easy-to-clean area Who It’s Best For: Perfect for medium to strong chewers or dogs that need something to keep them occupied for a while. Final Verdict: This is a great value and a go-to for keeping dogs entertained. I’d definitely recommend it if you’re looking for a longer-lasting treat that your dog will actually stick with! 🐾

🦴 The Ultimate Distraction: A Must-Have for Power Chewers!
Flavor Name: Bacon, Size: 1 Count (Pack of 1)
Finding a chew toy that can withstand my 70-pound "House Hippo" (an expert-level destructor) for more than ten minutes felt impossible, until we discovered these stuffed shin bones. These treats are an absolute game-changer for long-lasting entertainment, durability, and distraction. Exceptional Durability and Value: The bone itself is thick, natural, and surprisingly sturdy. Unlike processed chews that crumble or get demolished instantly, these last for days of chewing. The value is tremendous because they provide two phases of entertainment: first, the intense effort of licking out the filling, and second, the satisfying work of chewing the bone itself afterward. Irresistible Appeal (Peanut Butter/Cheese Filling): The filling is the secret weapon! My dog goes absolutely wild for the flavor. The filling is firmly packed inside, which means he has to spend a significant amount of time actively working to get every last bit. This intense focus buys me hours of peace and quiet, which is invaluable. On top of that, they offer good nutrition! Less Mess, More Fun: I appreciate that these bones are relatively neat. They don't leave greasy residue all over the carpet like some marrow bones, and the durable exterior means minimal splintering (though, as with any bone, supervision is required). They satisfy my dog's natural chewing instinct while promoting dental health by scraping against his teeth as he works the chew. Final Verdict: If you have an aggressive chewer who needs a serious, long-lasting treat that is both entertaining and structurally sound, look no further. These stuffed bones deliver on their promise and are now a staple in our dog treat rotation!

Still Going Strong Months Later
Flavor Name: Bacon, Size: 1 Count (Pack of 1)
These stuffed chew bones have been amazing for my dogs. Even months later, they’re still happily chewing on them, and that says a lot since they’re aggressive chewers. The bacon and cheese filling keeps them interested, and the bones themselves are durable enough to handle their chewing without falling apart. After all this time, the chews are still holding up and my dogs love them every time. They keep my dogs busy, help with dental care, and are definitely worth having on hand for large dogs who love to chew. Durable, tasty, and long-lasting—can’t ask for more.

Long lasting
Flavor Name: Bacon, Size: 1 Count (Pack of 1)
These are the longest lasting bones I have ever purchased. But if you don't want a heavy bone that makes noise when dropped this is not for you. They go sliding across my floor as they are being tossed around and played with. But they love them and they have lasted for months. I am glad they are not as expensive as others. To many things are over priced. Dogs love them.

Arrived on time and as described
Flavor Name: Bacon, Size: 1 Count (Pack of 1)
It is perfect for my 120 lb dog. He did give up after 6 hours of trying to get the “stuffing” out. The bone held up to his chewing. He loved it!
