General description

Rhodamine B-labeled, melamine resin-based microparticles (size: 10 μm) are a particle size standard, ideal to determine the particle size distribution (PSD) of test samples.

Application

Used for equipment particle size calibration with fluorescence detection.
Also used in:
  • fluorescence imaging applications[1]
  • optical sectioning studies of high-and-low-frequency (HiLo) microscope[2]

Features and Benefits

  • suitable for routine instrument calibration checks and corrections
  • delivered in 5 mL and 10 mL pack sizes as neat samples

Analysis Note

For every lot, exact values of particle size and standard deviation are determined with an accuracy of 0.01 μm using a Coulter Multisizer.

Questions

1–2 of 2 Questions  

  1. Can products be covalently attached through binding to the Rhodamine dye on the bead for the Micro particles based on melamine resin, rhodamine B marked?

    1 answer

    1. For Mico Particles based on Melamine Resin, Rhodamine B-marked, fluorescent, the fluorophores are not coated on the particles’ surfaces but are incorporated throughout their interiors. Plus, the amount of applied dye is below 0.2 wt.-%, or so. Hence, the approach of coupling anything via dye-borne functional groups is not very promising. Nitrogen centers of the polymer itself are not accessible for covalent bonds either.For coupling reactions whatsoever, it is recommended to use the micro Particles with functional groups such as 83088 and 88893, Micro particles based on melamine resin, carboxylate modified, rhodamine B-marked.
