RE: [Histonet] marking tiny specimens
Eyelashes are pointed at the end. Other body hair is not. I would re-use my tiny paintbrush over and over. No need to pull out an eyelash every day! Barbara S.

RE: [Histonet] marking tiny specimens
Cheryl So the eggs don't absorb the eosin at all or does the dye come out during processing? We use eosin all of the time for samples like that, but I leave them in eosin for about 10 minutes. Here is what we do, the fixed samples are normally submitted in Eppendorf tubes, we remove the formalin and replace with eosin (I use Anatechs), let sit for about 10 minutes and then very gently we use a plastic disposable pipette (the ones with bulbs) we place the samples in a tea bag and process on a very short cycle on the tissue processor (5 -10 minutes per station) we do this during the day so it's a continuous process.

RE: [Histonet] marking tiny specimens
Hi Cheryl, If you can, use more eggs. Then process them into a pellet with histogel. Upon sectioning, many different cross-sections will be visible in the same section.

We use a dropper of hematoxylin at the grossing table and it stays on the tissue even after processing. WANDA G.
