Hello

We are looking for very bright, monocolour (green or red), 50-100 nm fluorescent beads for some PSF test.
Does anyone know which beads are brightest?

Med vänlig hälsning / Best regards

Sylvie

Hi!

FluoSpheres are fantastic.
We use them routinely, much brighter than TetraSpeck beads (maybe 100x depending on bead size).

See this paper on fiducial correction using FluoSpheres:
https://iopscience.iop.org/article/10.1088/1361-6463/ab0862/meta

Product page:
https://www.thermofisher.com/uk/en/home/references/molecular-probes-the-handbook/tables/summary-of-molecular-probes-fluospheres-fluorescent-microspheres.html

Not very cheap unfortunately.

Best wishes,
Aleks

Hi,

apart from the existing and widespread FluoSpheres, we just received and
are going to test and compare the PSF of the yellow 50-90 nm beads from
SpheroTech (https://www.spherotech.com/up_to_5.htm , number FP-00552-2).
We'll know more on their brightness the following days.

Best

Orestis

Can anyone recommend a source for beads made of a material other than
polystyrene? I'm looking to make measurements in dibenzyl ether, which will
dissolve styrene beads.
Thanks so much,
Drew Friedmann

Dear Sylvie,

I would contact ThermoFisher and ask if they have FluoSpheres in green and red in size 40 nm or 100 nm in storage (https://www.thermofisher.com/us/en/home/references/molecular-probes-the-handbook/tables/summary-of-molecular-probes-fluospheres-fluorescent-microspheres.html).

Some of these beads are currently not listed on their website but believe it or not, you can still order them.

I have performed some of my Ph.D. experiments with Crimson 100 nm beads that do not exist, according to their website.

An entire custom-made batch costs approx. 12,000 Euro, but occasionally, labs order them custom-made, and ThermoFisher still might have some of these not listed beads in store.

Best of luck.

Best regards,

Ulrike

Hi Drew.
I would go for golden beads and measure in reflected light.
Best.

Sicastar beads (made out of silica) work in DBE:
https://www.micromod.de/de/produkte-3-fluoreszent.html

I don't know of any silica beads with more than one fluorophore, and would be interested to hear if someone else has found any.

Can anyone recommend a source for beads made of a material other than polystyrene? I'm looking to make measurements in dibenzyl ether, which will dissolve styrene beads.
Thanks so much,

Hi Drew,

you should have a look here, they have a lot of different non styrene
beads coming in many sizes and with different fluorophores:

I have no commercial interest.

Hi Drew,
my favorite Expo Neon dry erase marker beads are quite resistant, I suspect
melamine, but I'm no chemist. I haven't tried DBE, but they do not dissolve
in acetone. Note that they are quite big, about 0.3 um.
Best, zdenek
