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.

Dogs love them
Size: 3.5 Ounce (Pack of 1), Style: Chicken Chips
I would have gave 5 stars, but you have to tear/cut into small pieces because they are hard for dogs to chew and swallow. Will buy again.

Dogs all beg for them!
Size: 3.5 Ounce (Pack of 1), Style: Chicken Chips
When I first received the package I was concerned about the small size of the crisps & the package itself. Not to worry! They are rather thick, and I had to half them for almost all of the dogs. They must be delicious because the dogs all gather around the corner of the treat table with the chicken chips! It takes them more than 2 seconds to chew, as well. I’m definitely reordering.

Perfect for my picky dog who cannot do hard treats
Flavor Name: Bacon & Apple, Size: 5 Ounce (Pack of 1)
My dog loves these treats! Good ingredients, great size and value. And perfect for my picky little man. I also love that these don’t have a strong smell!

My 3 Vote Yes
Flavor Name: Bacon & Apple, Size: 5 Ounce (Pack of 1)
All three of my dogs LOVE these! There aren't a lot in the package for money. But the jerky pieces are big enough and soft enough that I was able to break them to make them last a little longer.
