Does anyone work with or know of any company that sells cell line
gelatin that has color ? blue? red? 
I plan to make a cell line pellet to be embedded  for the use of tissue
array. Since the paraffin and the pellet are similar in color it is hard
to distinguish the pellet from the paraffin while sectioning. Therefore,
having gelatin with some color would alleviate that problem.

Thanks in advance.
