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.

Almost perfect...upraised logo should be left off
This toy is great for relentless chewers with strong jaws! It would be almost perfect if it didn't have a "K9" logo in raised rubber on it. That is the place that my aggressive chewer shepherd/bulldog mix focuses on and is able to get small chunks off. Without that logo, he would chew the ball more evenly, instead of fixating on that one spot. He loves this ball and has chewed on it for about an hour off & on each of the 11 days he has had it. Although it is very durable so far, the flaw is the upraised logo.

Perfect for High-Drive Dogs & Surprisingly Durable (six month review)
I use this ring ball for structured fetch and tug sessions with my high-drive German Shepherd mix (91 lbs. at 10 mon.), and it’s easily the best toy we’ve added to our routine. What makes it truly exceptional is how it allows my dog to engage in the full canine predatory sequence: • Chase: He locks in visually and bolts after the ring when I throw it. • Grab & Hold: He brings it back, pins it against my leg, and bites down firmly (the toy—not the leg!)—his way of acting out the natural catch-and-control behavior. • Unalive & Tug: We finish with a strong tug session, which satisfies his instinct to grip and shake—basically his version of “making the toy unalive.” • Settle & Chew: Afterward, he relaxes with a chew toy or eats—completing the full physical and mental cycle in a healthy, balanced way. Durability is outstanding—this toy stands up to intense tug sessions with no tearing or damage, even with a 91 lb powerhouse. My senior dog also joins in for double tug play, and it holds up beautifully to that too. I don’t leave this toy down for chewing—it’s not a chew toy. I use it specifically for fetch and tug, then put it away when we’re done. This keeps it exciting and extends its lifespan. My dog has other chew toys he can use freely throughout the day. This isn’t just another fetch toy—when thoughtful it provides a structured, instinct-satisfying experience that’s mentally enriching and physically engaging. If you have a high-drive or working breed, or a dog who thrives on interactive play, this ring ball is 100% worth it.

Love these!!!
Color: Black and White, Color: Black and White
I absolutely love these socks!!! I use them so I can walk around the house when I put lotion on my feet. They are perfect. Very very smart young lady that came up with this idea.

The best freetoes socks ever
Color: Black, Grey
Love this toeless socks so much! I could wear it all day. Very comfortable! It is just the right thickness which is suitable in summer time or cold weather as well. Most of the toeless socks I have seen have the gel on the heel area and I don't like the feel of it. I'd rather apply lotion on my heel then wear the socks. I have had some issues with the packaging from Amazon and I made the maker of this said socks aware of it. Julia Bebben was very prompt in her response and very helpful. Thank you Julia for your excellent customer service.

great concept, just one tiny annoyance...
Color: Black, Grey
i love that a sock that lets your toes be free is even a thing that exists. i love that this company was started by a young girl, now turned young businesswoman. i have pain in my big toes, so i can't wear close toed anything, but feet get stinky if you wear shoes/slippers all the time without socks. this is a great solution. the only thing i find slightly annoying (not enough to stop using these) is the seam on the bottom of your foot, near the base of the toes. it is a straight line, which is fine on the top of the foot, but i wish the bottom itself curved a bit, to follow the line of the toes. as it is, the seam lands right in the middle if the ball of my feet, so i can feel the seams everytime i take a step. i am constantly pulling the seam toward the toes, to try to keep from feeling it, but then my pinky toe gets caught and balled up on the inside. outside of that slight annoyance, they're comfortable and fit well.
