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.

Fun read
Format: Kindle
I'm not really into mafia books but I love Roxy Collin's other series so I decided to give it a try. It had the same great romance, spice, swoon-worthy characters and exciting plot that are her signature. Arben was my favorite, although it was a bit sudden how quickly he changed from ignoring her to wanting to be pack. There were almost too many twists/layers of lies to keep track of but I'm looking forward to reading the other books. The only thing that detracted from the story for me was the need for a bit more proofreading. It was mentioned that Kelly is a female and male at different points, leading me to think she changed her mind at some point about the character's gender but didn't go back and edit it to align in all places. Like another reviewer pointed out, step siblings are different than half siblings. They are incorrectly referred to as step siblings because they (allegedly) share the same biological dad. There are a few other typos as well but those aren't a big deal.

Stepbrothers, Secrets, and Sizzling Heat
Format: Kindle
Twisted Lies by Roxy Collins is a wild ride through family secrets, amnesia, and a steamy stepbrother romance. When Kelly discovers her life is built on lies, she ends up tangled with three alpha stepbrothers and an assassin who once helped her through a heat. The tension? Off the charts! The heat is real, and the complications are messy in the best way. Full of twists, secrets, and fated mates? You'll be hooked from page one! Love omegaverse drama with a dash of taboo? This one's for you!

Good read
Format: Kindle
The book has some good twists and turns, but truthfully I was so confused on some things. It didn't have a good flow for me personally. Not sure if it's due to typos or using him/her wrongly, but I thought Kelly was both a guy and a girl. Actually I still don't know, and it made me incredibly frustrated. It would refer to Kelley as him or he, and then again in another part of the story as her she and sister. On to the next book, I hope there is some clarity and a smoother flow. This is a slow burn, and I just don't know how much I care for the Alphas yet. Idk if I recommend.
