Product Name

Name:Carboxyl modified red fluorescent polystyrene microspheres

Product Overview

Carboxyl modified red fluorescent polystyrene microspheres are prepared by adding a red fluorescent dye that excites around 532 and emits around 612 during the preparation of polystyrene microspheres, and then modifying them with carboxyl groups. Customizable size range of 20nm-5 μ m. These microspheres have a uniform particle size distribution, which enables them to exhibit consistent performance in various applications. Fluorescent dyes are embedded inside the microspheres, effectively preventing fluorescence quenching and reducing the influence of environmental factors on fluorescence intensity.

Technical Parameter

Appearance: yellowish lotion colloid

Fluorescence wavelength: 498-516nm

Concentration: 10 mg/mL

Ingredients: Polystyrene, Ultra Pure Water, FITC Derivatives

Product Features

Monodispersibility: The uniform particle size distribution of microspheres helps ensure consistency and reproducibility of experimental results.

Fluorescence characteristics: Contains highly fluorescent dyes that are embedded inside the microspheres, effectively preventing fluorescence quenching.

Adjustable particle size: By controlling the synthesis conditions, microspheres with different particle sizes can be prepared to meet different application requirements.

Surface functionalization: The surface of microspheres can be chemically modified by introducing specific functional groups, such as carboxyl and amino groups, to achieve specific biochemical functions.

High stability: Microspheres have good chemical and physical stability and are suitable for use in various environments.

Optical performance: The fluorescence emission of fluorescent microspheres is stable and not affected by changes in external environmental media.

Application Fields

Biomedical research: Fluorescent polystyrene microspheres can be used for cell labeling, imaging, and as carriers for drug delivery systems in fields such as cell biology, molecular biology, and biochemistry.

Standard measurement: As an instrument calibration particle, used to calibrate analytical instruments and ensure measurement accuracy.

High throughput drug screening: As a signal carrier, it helps to quickly screen a large number of compounds and search for potential drug candidates.

Medical diagnosis: In areas such as immune analysis and detection, the surface of microspheres retains their original functional groups, which will not affect immune analysis and detection.

Tracer research: In fields such as phagocytosis research and pore size determination, fluorescent microspheres can be used as tracers to monitor cellular endocytosis processes.

Hana approved, gold star toy
Color: Original Pack, Color: Original Pack
This is, according to Amazon, our 11th set in 3 months. According to Hana, our shiba/chi mix, this toy is immaculate. Crunch score is a 10/10 and the squeak? Don't get her started. High pitched, easy to squeak and protected by just enough crunch and fabric that it actually lasts. In fact, she will tear the toy open before the squeaker gives up. This may seem like a small feat, however most toys last 12-30 minutes before the teefies take the squeaker out of commission. Lambchops last about 15 minutes before the squeaker gives in and fluff decorates the floor. The only reason we buy so many so often is because 1. The teefies do eventually puncture and the moment that happens she guts the poor Claw instantly. And 2. She has about 11 teefies, so the mouth gets kinda icky and due to the crunch, washing these kind of sucks- retains a lot of water and cant dry. So we replace them often even if she doesn't get to the gutting. 10/10. Its her favorite toy. And we've tested a lot of toys.

These are ADORABLE!
Color: Tropical Pack, Color: Tropical Pack
These are adorable! I got them as a gift for my in-laws pups and when I was taking pics of them my dog now wants them soooo I’m going to order more for her! They are so soft and the details are hilarious! Just be careful because the pawcohol content is pretty high so I’m sure your dog will be feeling it after just one! 🤣🤣🤣🤣🤣

My dog loves these toys!
Color: Original Pack
My dog is obsessed with these toys! We jokingly say that he’s a “doggie alcoholic” because he seems to not destroy any toys like this. They’re very soft and each of them has a squeaker! He’s a German Shepherd so they’re a little on the small side, but he loves them none-the-less! Wouldn’t recommend for tough chewers if you’re looking for something that lasts, but they’re cute and fun either way! Love the fact that they’re made by a small business as well. Will have to update with a picture in a bit!

Great Toy!
Color: Tropical Pack
These are great! I bought last Christmas for our pup- a 17 lb Aussie doodle. She’s pretty rough on toys. Usually pulls the stuffing right out in a few days. But these have lasted all year. Came back to buy her 2 new “flavors” to put under the tree.
