[Robyn Vazquez]

Joyce,
How much baby powder do you use, per bottle of OCT?  
 
Thanks
Robyn

Please the tissue in baby powder and it will eliminate the air bubble.
You can also add baby powder to the OCT and it will give it more "body"
for holding the tissue correctly for freezing. I don't remember where I
heard this or learned it... I just know it works! Hope it works for you,

Subject: [Histonet] frozen sections


hello, has anyone observed empty space surrounding tissue frozen in 
O.C.T. or similar tissue freezing medium after snap freezing? Upon 
sectioning samples shipped previously snap frozen to one of our 
researchers I noticed space surrounding various areas of the tissue. 
Does anyone know what probably caused this? Could this be a factor in 
the generation of horrible sections? I suspect the tissue may be moving

when the blade touches it. Is there a know remedy that will not damage

the tissue? Has anyone ever added O.C.T. to already frozen tissues? Any

assistance will be much appreciated. Atoska
