Finally i can label Hela cells with MJ and Aluminum
The less volume the more labeling efficiency...

Who did MTT test and see Formazan cristals?

I combine Ai and Mj to produce a fluorescent for Hela cells. Their combination is great but it doesn't work with cells!?!

Happy #FluorescenceFriday
Some cells and bacteria are still alive. #microscopy
AO & PI staining

Happy #FluorescenceFriday everyone.

Here's another mouse neocortex (🔵 NeuN, 🔴 tdTomato, 🟢 GFAP, 🟣 DAPI).
This one was transfected/electroporated early in development (E13), but you can still see the injection site in this hemisphere at P10.

L929 cells on a scaffold

These are L929 cells were seeded on a 3D printer scaffold.
The researcher didn't know how to see the cells due to the thickness of her scaffold. When I irradiated the UV light from upside her sample and she was able to see her cells, she was going to cry😊.
