amino acid mixture

[Michael L. Sullivan]

One method I've seen used is to combine the dry amino acids and ball 
mill the mixture so that the particles are very fine, assuring that 
even a small amount will be the uniform mixture you want. An 
appropriate amount of the powder is then added directly to your media 
when you are making it.
