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.

Good quality, good price, bad shipping tho

Honestly I was really happy with the iPad. The one I got was RENEWED in Excellent quality. I will start off by saying that it was poorly packaged during shipping and the iPad box was severely damaged, but luckily my iPad was just fine. The iPad came decently, but not fully, charged and was quick and easy to set up. The battery life does not last as long as my Galaxy Note 20 Ultra, but I am also sure I do not have it optimized for battery saving. I got this iPad for 2 reasons. 1) To be a pseduo laptop with a keyboard case for school, and 2) procreate. I am overall happy with the item. I'm just sad I found a better deal on the exact same model sold at Walmart and its in pink (;-;). The item functions well, and is as described, it was a really good deal

I purchased it to program Harley. Pretty nice
Color: Silver, Memory Storage Capacity: 128 GB, Set name: Wi-Fi + Cellular
I've never had an Apple product before, the charging is slow, I love it because it's very light and durable I got it on sale So the value is very good. It's very thin also which I do like that and the collars are very bright and clear... I did drop it but from a low distance in the durability is great. Never damaged it a bit

Item as described, mint condition, works great came with charger block and fast shipping only issue I had is with shipping carrier. FEDEX stinks showed arrival as Monday, was delivered 1/21 10:45 am yet their system showed package was in Louisville, Tn at this time later in the evening I checked again showed delivered. No package by my door from FedEx had to go to their website to find picture where the left it. Was found at entrance to my complex on top of mailboxes where anyone could have of taken it…
