O-acetylated sialic acids

[Kurosaka Akira]

I want to fractionate sialic acids from bovine submaxillary mucin
to obtain several types of O-acetylated derivatives in a preparative 
scale.

I would greatly appreciate receiving e-mail on the method of 
preparative isolation of O-acetylated sialic acids at the 
following address: kurosaka at cc.kyoto-su.ac.jp

Thanks in advance.
