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.

Doesn't last long

I have only had this pillow for 8 month and it is flat and not comfortable anymore. I sent the company an email and they never responded. I do now recommend that you buy this pillow.

The pillows have a chemical smell
Size: King (Pack of 1)
I bought two Marlow pillows a while ago. They are great pillows. The two new Marlow pillows I just purchased have a chemical odor. The manufacture date is Sept. 2024. I have them airing out hoping the smell will dissipate , so far that has not happened.

Simply The Best
Size: King (Pack of 1)
It appears there are more than 1,000 pillows advertised and available all over the Internet. The situation is a comedy routine. If you want a cooling pillow because you're a hot sleeper or if you want a plush pillow for back problems or a combination or neither, it doesn't matter. Be prepared to read 1,000 different advertisements until you start laughing out loud. This is what I did, but I wandered upon this Marlow Pillow system and then trusted the Amazon ratings. And boy am I happy, though a word of caution: if you want the cooling technology to really work you've got to pair this pillow with the Marlow pillow protector. Because Amazon didn't carry the pillow protector I bought it directly from Marlow. And this is the last pillow I'll ever get or need to get. Comfortable like a goose down pillow and yet cool to the touch and cool all night long. So I got lucky; have avoided having to buy multiple pillows; and now am enjoying the heck out of my Marlow King with the Marlow pillow protector. Lastly, this pillow is adjustable with a zipper and it works: you can make it softer or harder with a quick zip. The best pillow out there, by far!
