Re: [Histonet] reversible tissue adhesion to slides

From:Philip Oshel


How about attaching the part you *don't* want? That way the 
dissection will also release the desired tissue. Use a minute (no! 
smaller! still smaller ... ) drop of superglue to hold the tissue to 
the slide -- the same glue used to glue fresh tissue to the mounting 
plate of a vibrating microtome.
