Dear Histonetters,
   I'm making my first batch of MMA and have a
few questions.  I see so many different
formulations for the infiltration and embedding
mixtures, I'm confused.
  Diane Sterchi's formula for embedding is
95 ml MMA
1.5-5.0 gm benzoyl peroxide
5 ml dibutyl phthalate
10 gm polymethylmethacrylate

  Peter Jackson & David Blythe's formula is
15 ml MMA
5 ml dibutyl phthalate
1gm benzoyl peroxide
125 ul N-N dimethyl aniline

I see a greater amount of the dibutyl phthalate and
benzoyl peroxide in Jackson's formula.  Also,
what does the dimethyl aniline and the
polymethylmethacrylate do?
thanks for the help,  Sarah Christo, Texas A&M
