Hi 
H&E Stain is very important in the Diagnosis. understaining can be caused by many factors, check the age of your hematoxylin or the concentration of your differentiating solution.
Then to restain the stained slide .place the stained slide in 1%  acid alcohol for 2-3minutes and rinse well in distilled water.
then restain in hematoxylin for the required time.You should be fine .

Hello:
I was doing H&E's and it was pointed out that I had understained the hematoxylin. But the eosin was ok. How does one go back and restain the slides and remove the old stain?  Or do you use a differentiating solution?

Thanks for your help

Happy Holidays

Can someone tell me the best stain to use for Charcot Leyden crystals?
We are looking for them in feces.  Thanks.

I work with a tech that you, Melissa, said was getting $1,000 after her
placement.  After five months, multiple phone calls, and letter writing she
only got $500.  You wouldn't get back to her.

Joe,

I would make sure all the mountant is removed. A good soak in xylene and
then a rinse in alcohol, if the mountant has not fully disappeared, you
will see a white opacity on the section.

Rinse in water and then re-stain as usual. The eosin will tend to leach
out in the water rinses and the differentiation solution (after the
haematoxylin - if you use it). Check the sections after blueing.. If it
looks too weak, increase the Hx staining time &/or decrease the
differentiation step. Counterstain with eosin as usual and you should be
right.

Hazel

Charcot-Leyden crystals are frequent findings in faecal samples and sputum submitted for microscopical study, the crystals are easily demonstrated,if present,  by making a simple 'wet' prep and adding a drop of Gram's Iodine under the coverslip.

Charcot-Leyden crystals in faecal submissions should lead the investigator to seek the presence of parasitic infection from particularly helminthiasis. Note that Charcot-Leyden crystals are virtually absent from samples of bacillary dysentery, but are frequently found in samples of faeces containing the various amoeba spp. Several other intestinal parasitic worm species result in the presence of Charcot-Leyden crystals.

Within sputum Charcot-Leyden crystals are found in cases submitted from bronchial asthma sufferers, the crystals are often found within Curschmann's spirals that are a feature of this disease. Lung diseases such as Paragonimus ringeri & P westermani , typically found in the region of the Phillipines and Japan, are fluke diseases that result in the presence of Charcot-Leyden crystals from the haemoptic sputum.. The crystals have also been found in pus from amoebic liver abcesses that have found their route of discharge through the lungs. 

Hope this info is helpful to you.

A very happy Christmas & New Year to everybody out there in Histoland.

Dear Histologists,
Does anyone have a good protocol for doing TUNEL on fixed brain slides?
Thanks
