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.

ABSOLUTELY A MUST for Omegaverse Girls!!!
I ABSOLUTELY LOVE Jillian West and her books!!! I’m so happy I already bought book two and now I have to buy the others for the Assurance Security series!! Not gonna lie Val kind of annoyed me at the beginning but she grew on me!! Her men are chef’s kisses!!! Holt annoys me some but I can let it slide. I already bought part two so I’m going to be reading that in between work phone calls!!!! DON’T TELL MY BOSS 😂😂😂😂

Baby bumps and bodyguards
Format: Kindle
Dark, emotional, and unexpectedly tender, Not Ready is an omegaverse romance that delivers found family feels, fierce protectiveness, and a very pregnant heroine who refuses to break. Vale’s on the run from a stalker, but lands in the arms of three private security alphas, cue the swoony tension, fake marriage twist, and slow-burn heat. It’s a little gritty, a little soft, and a whole lot addictive. If you love protective alphas, high stakes, and heroines with quiet strength, this one’s a must-read.

Strong Omegaverse Comfort and a Attention Grabbing Plot
Format: Kindle
Jillian West never misses when it comes to Omegaverse, and Not Ready is no exception. This story was the perfect blend of cozy comfort and emotional depth while still delivering a strong plot. Vale is such a powerful heroine, she is strong, capable, and determined but I love that she still allows her pack to love and take care of her. It’s that balance of independence and vulnerability that makes her so relatable. The relationship dynamics were amazing: Bishop is steadfast and completely head over heels, Mercy is skeptical but protective in his own way, and Holt is the hesitant one whose slow fall is so satisfying to watch unfold. The romance hits that sweet spot between insta-love and cautious build, keeping me hooked the entire way through. And that ending. Oh my god, the cliffhanger! I need the next book in this duet immediately.

Interesting
Format: Kindle
So I will say I enjoyed the story, for sure had its moments where it dragged but it was a great story. I really liked that omegas picked their alphas/make the pack. Normally the Alphas make it and the omega fits in with them which is great but I enjoyed this new version where all the power basically went to the omega. It was a nice change of pace. I can admit some of the weird bedroom stuff with her being pregnant was odd, it’s really not hard to do stuff when pregnant (I know I’ve had two and it’s normal and even encouraged at the end especially if you want the baby out). But I like the story as a whole and will read the second, I do hope the next one isn’t dragged bc it stopped being action or tense after she met her alphas and I don’t think it was brought up or properly done when they tried to do it. More sweet after she left.

I’m a little disappointed.
Format: Kindle
I usually like Jillian West’s books but this one was missing a lot for me. The pregnancy didn’t come across as real. She’s on her feet for 12 hour days but is perfectly healthy at 8 months pregnant? Yet the week she moves in all of a sudden she’s not? She is planning on actually running during one of the plot buildups. But at 8 months pregnant that’s incredibly hard to do. The lack of breathing ability and lung space, the change in body center, mass, and gravity. All of it prohibits running, unless you’re an athlete this didn’t come off as at all realistic. I didn’t feel any connection with the alphas. There wasn’t any emotional connection. It could be because of the tense it was written in. But I didn’t get any deep feelings out of this. It came across as checking off boxes. Even the spicy scenes weren’t really believable for me. I wanted to see them fall for her, and it just kind of all fizzled. Even Bishop. One thing I did really like was the ending. I did not see it coming and I’m interested in reading book two because of it. But on the whole this book was mostly disappointing for me.
