I am trying to identify components of wheat straw stems.  I want to look at
the use of Ruthenium Red and whether this stain will help differentiate
cells and other materials in harvested stems.  I have found a couple
references that provide concentrations of RR to use but I do not have a
complete prep-protocol for use of this stain.  Can anyone provide me with a
staining procedure for ruthenium red and slide prep procedure?

Thanks!
