Product Name

Aminated magnetic microspheres

Product Overview

Aminated magnetic microspheres are magnetic particles with surface modified with amino functional groups and superparamagnetic properties, which are widely used in biomedical and molecular biology research. The 1um aminated magnetic microspheres are composed of polystyrene and iron oxide nanoparticles, which are hydrophilic and biocompatible. The aminated magnetic microspheres are superparamagnetic, have fast magnetic response, good monodispersity, and ensure homogeneity of reaction and consistency of detection. The unique surface roughness structure and polymer modification make the aminated magnetic microspheres have high amine density, which can be covalently coupled with peptides, proteins, oligonucleotides, drug molecules, glycoproteins and other biological ligands under the action of special chemical reagents (e.g., glutaraldehyde), and can be used as a good base material for encapsulation, which is an important carrier tool in medical and biomolecular research.

Product Features

 

Superparamagnetism: Aminated magnetic microspheres are superparamagnetic and can be rapidly magnetised and show magnetic properties under an applied magnetic field, and then quickly lose their magnetic properties when the magnetic field is removed, facilitating manipulation and separation in biomedical applications. 

Surface Amino Functional Groups: The surface of these microspheres is rich in amino functional groups (-NH2), which can be covalently coupled with biomolecules (e.g., proteins, antibodies, oligonucleotides, etc.) via chemical cross-linking agents to enhance their functionality in biomedical applications. 

High specific surface area: Due to their nano or micron scale particle size, aminated magnetic microspheres have a high specific surface area, providing more active sites, which is suitable for immobilisation of biomolecules and catalytic reactions. 

Good biocompatibility: Aminoated magnetic microspheres are usually made of biocompatible materials that are safe to use in living organisms, reducing immune reactions and toxicity. 

Easy modification and functionalization: The surface of aminated magnetic microspheres can be modified by various chemical methods to introduce different functional groups, thus expanding their applications in biomedical fields.

Application Fields

Protein Separation and Purification: Aminated magnetic microspheres can be used for the separation and purification of proteins. By forming covalent bonds with specific amino acid residues of proteins (e.g. lysine), efficient separation of proteins is achieved. 

Cell Separation: These microspheres are also used in cell separation, where magnetic separation of cells is achieved by specific binding to molecules on the cell surface. 

Enzyme immobilisation: Amino magnetic microspheres can be used for the immobilisation of enzymes, which are covalently bonded to the surface of the microspheres, improving the stability and reusability of the enzymes. 

Immunoassay: In immunoassay, the aminated magnetic microspheres can be used as the material for the preparation of immunomagnetic beads, which can be used for immunoassay and analysis through covalent coupling with antibodies or antigens. 

Drug delivery: Aminoated magnetic microspheres can be used as drug carriers to achieve targeted drug delivery through surface modification. Under the action of an applied magnetic field, the microspheres can be guided to the diseased area, improving the efficacy of the drug and reducing side effects.

Related Information

Aminated magnetic microspheres 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 before unsealing.

Not for Honda Civics
I just want to start with saying that this is beautiful and very high quality. I really wasn’t expecting much with the price point being so low. But the cover is very soft and cozy. It is too big for my 2018 honda civic center console, I really wish it fit because I love this thing! I’ve just had it next to me while I sit on the couch and have been petting it the last couple hours. I’ll find somewhere else to put it because it’s that soft and pretty. If this will fit your car than I 100% recommend it!

Very pretty, has a bit of a smell
Only docking this item one star because of the smell. It's genuine sheepskin so it definitely smells like.... sheep. I've never bought genuine sheepskin before so I'm not sure if that's always the case. I think after it airs out for a while it should be fine, but it was a little off-putting for me at first. Besides that though it looks BEAUTIFUL. I bought it to cover up some dog claw marks on the center console since I got my car used. It covers them up, and also makes my car look fancier. I think it should last a long time as long as I make sure to not spill anything on it. Overall, it seems very well made, is super soft and comfortable, was good value, fit really well on the center console (I have a Subaru Forester), and it was totally worth getting.

fits 2013 honda civic, fades to a weird blue and looks matted scruffy
Fluffy and cute! This is all I hoped it would be. It is a piece of real sheepskin with a couple of pieces of elastic sewn to the bottom to attach it to the console cover. This makes it somewhat versatile concerning fit. It is just long enough for the console in my Honda Civic, which I believe is about 11 3/4 x 6 inches. The fluffiness of the cover allows for some slack in coverage, so it does adequately cover my console. I was pleased to see that I actually got the long-haired one. I am very pleased with the product. If it hadn't worked in the car I might have kept it in the house to pet it! Update: Over a few months the silver fur, which I thought was a natural wool color, has faded to a washed out pale aqua, and this looks very scruffy. The elastic bands that hold it in place over the console show now that it is less fluffy. I will probably wash it and see whether that will improve the situation, but I suspect this will renew the curl, and leave the band exposed. I have downgraded this to a 3 from a 5. Further update: This looks terrible. Very scruffy, slides around. I did wash it, but it did this did not renew or make it look like natural sheepskin. Whatever processing and dying they did not this seems to have removed the natural curl. I would have preferred no dye and processing, and a natural piece of sheepskin, probably bigger to account for getting matted and smaller as it ages. Note: This one is bigger than some of these on Amazon, so measure your console and consider the size. This one barely fit when it was new.

Love it !!
Color: Black
I have own sheepskin covers and this armrest cover didn’t disappoint. I bought this for a friend and she loved it. Soft and keeps its fur like shape. The fur did not clump after being used. I would definitely recommend.
