Hello! 

I use 7% gum Tragacanth that I make up myself using 100ml of distilled water, 7gms of gum Tragacanth, and 5 grains of Thymol. Dissolve by manually stirring at rm temp.(may take several hours) Store half refrigerated(4c) and half frozen  
 (-20c). I work with only muscle and nerve biopsy tissue but this works great for me. I am sure this is a bit "old school", but I have never had any trouble with cracking or stability of the tissue. It also seems to be great for long term storage in -80 freezer. Good luck!!

Subject: [Histonet] Is there anything better than OCT? 



Hi all: 

We are currently using OCT to embed renal biopsy tissue in cryostat mold. First of all ,we put a drop of OCT on the mold ,then we put the tissue on the top of the OCT and dip the mold into liquid nitrogen for 10 seconds. then the tissue is sent to cryosection. Does anyone know if there is anything better than OCT to embed the tissue? 

Thanks!
