to fixed the blood smear
because giemsa stain is a mixture of methyl acetate Eosin and azure b. it doesnot contain any fixative that is why we use methanol to fix smear during giemsa stain other stain like lieshman contain acetyl free methyl alcohol as a fixative so it does not need to fix slide stain with lieshman stain.
It depends on what tissue you're looking at, what you want to stain, how the tissue has been stored... Besides very specific staining, there are different types of staining. For example, immunohistochemistry, which uses antibodies to stick coloured stains to cell surface receptors. Or, chemical staining - the most common is H&E staining (haemotoxylin & eosin), so if you're just having fun in a lab and want to see general structures of cells, use this one.
1. stain with leishman stain for 3 minutes 2. poured with buffer solution for 10 - 15 minutes, make sure the blood film is flooded with the buffer solution. 3. rinse with distilled water to clean the remaining stain. 4. air dry. this is the most simple step and easy to remember! good luck!
