When I was isolating RNA from leech(annelid) with hot-phenol method,
I couldn't remove black-colored pigments from RNA. I treated proteinase K,
however, the pigments were remained after treatment. When I used
LiCl, the yield of isolated RNA was too low. As I think, pigment might
bind to RNA when the leech was homogenized.
How can I remove pigments (or ?) from RNA?
