What you do at the sample site depends on what the research is all about.
We used to do the following:
1- at the site  we took 4 to 5 smears and fixed the core in neutral (but really neutral) buffered formalin, inside a glass container (2-3 oz.). 
2- after 4-6 hours the biosy was places in EDTA and was "decalcified" for 4-6 hours and latter processed, cut, stained, etc. as usual.
3- the liquid and remanent blood contained in the vial was filtered through paper filter, placed in cassette and processed in the same way as the biopsy.
4- both decalcified biopsy and filtrate of aspirate were cut as thin as possible, except for the slides used for iron or reticulin stain, that were cut at 7 um
Hope this will help!

Hi all - I have a residen whose research will include doing bone marrow 
biopsies. Could someone help me with protocols for bone marrows. Vet Med 
here does not routinely do bone marrows and the results are spotty. What I 
am looking for is what you do at the point of biopsy, as make smears, fix 
some, etc., what fixative do you use, do you decal the BM and in what? All 
that "stuff". If anyone can help me, it would probably be better to e-mail 
me directly. Thank you,
