Name:Streptavidin-modified Fe3O4 particles

Product Overview

Streptomycin modified iron oxide particles are modified with streptavidin on the basis of iron oxide particles. The high affinity binding between biotin and streptavidin is the basis for the development of this field. Biotin is a small molecule that can be covalently attached to various biomolecules, while streptavidin can specifically recognize and bind to biotin.


Technical Parameter

Form: Solution

Diameter: 40nm, 100nm (customizable)

Ingredients: SA@Fe3O4 Ultra pure water


Product Features

High biocompatibility: The surface modification of iron oxide particles gives them good compatibility in biological systems.

High sensitivity: Due to the high affinity between streptavidin and biotin, these particles exhibit high sensitivity in detection applications.

High specificity: The streptavidin biotin system provides highly specific binding.


Application Fields

Biosensing: Utilizing the high affinity between streptavidin and biotin, SA@Fe3O4 Particles can serve as biosensors for detecting the interactions of biomolecules.

Magnetic resonance imaging (MRI): Due to the magnetism of iron oxide, SA@Fe3O4 Particles can be used as contrast agents for MRI, improving the contrast and resolution of imaging.

Cell separation and enrichment: By utilizing the magnetism of magnetic nanoparticles, specific types of cells can be easily separated and enriched from complex samples.

Indestructible
Style: Fetch Balls (Pack of 2), Size: 3 inch
These balls are indestructible! We have a lab and a lab mix and they CANNOT damage these balls. They love them for fetch and to just chew on them (slightly squishy, but NO damage). Best toys we have bought for them.

Great trial set. Just be careful throwing the orange one!
Style: Assorted Balls (Pack of 3), Size: 2.5 inch
Blue isn't that easy to see in the yard White charges with bright light/UV and is truly a game changer for night-time fetch. Both dogs clearly favor it. Orange is easy to see in the grass at day They're 3 different weights as well, so double trial. I prefer medium for my big dogs, though light performs well too The orange is HEAVY and unyielding. Do NOT throw it with a ball thrower. It could damage your house or knock your dog out. Seems tough though.

They work! Even if you hate socks
I am not a sock wearer. Can't stand having my foot entirely shrouded in cloth. I don't wear socks with my sandals, slides, clogs and other shoes most of the year. Only on the coldest winter days. I know, It's weird. So, with my sock phobia one thing that happens is your heals get dry and rough. I opted to try these because the toes are free. I barely notice the socks on my heels/ankles when my toes get air (outside of bedcovers always). I put good thick lotion on my heels and sides of feet. A little less on the toes so they don't stain anything. The silicone lining on the heel holds that lotion against the affected areas. In a couple days my feet felt soft and looked pretty. No cracks, no white roughness. They look pink and freshly spa-ed. Fit is good on size 9 feet with thickish ankles. Highly recommend.

Nice Socks, Bad Shipping
The socks are definitely worth the price. They are cozy and non constructive. They colors are nice. My only complaint is the method in which it was shipped. Slapping a mailing label on a clear bag is not acceptable. The shipper didn't consider protecting my privacy. I hate to think if it was something extremely private. Consumers deserve better when it comes to the content of their mail.
