[Histonet] preparation of chromic acid solution for CAS....

[Ul Soo Choi]

Hi, histonetters! 

I am interested in CAS chromic acid Schiff stain, instead of PAS. 
The following article prompted me to change it with CAS.

But, I am not aware of the protocol how to prepare chromic acid solution. 
Also I am still just wondering if CAS produces more distinct and good contrast
than PAS in the tissues, and cytology samples. I usually use cytological specimens. 

I would like to hear your experiences on CAS. 

Let me hear.....

Thank you always.
