L-Arginine (mw: 174.20 g/mol)	0.05 g	0.000287 M
L-Aspartic acid (mw: 133.10 g/mol)	0.08 g	0.000601 M
L-Histidine (mw: 155.15 g/mol)	0.02 g	0.0001289 M
L-Isoleucine (mw: 131.17 g/mol)	0.05 g	0.0003811 M
L-Leucine (mw: 131.17 g/mol)	0.1 g	0.0007623 M
L-Lysine (mw: 146.19 g/mol)	0.05 g	0.000342 M
L-Methionine (mw: 149.21 g/mol)	0.02 g	0.000134 M
L-Phenylalanine (mw: 165.19 g/mol)	0.05 g	0.0003026 M
L-Threonine (mw: 119.12 g/mol)	0.1 g	0.0008394 M
L-Tryptophan (mw: 204.23 g/mol)	0.05 g	0.0002448 M
L-Tyrosine (mw: 181.19 g/mol)	0.05 g	0.0002759 M
L-Valine (mw: 117.15 g/mol)	0.14 g	0.001195 M
Uracil (mw: 112.09 g/mol)	0.02 g	0.0001784 M

Prepare 800 mL of distilled water in a suitable container.
Add 0.01 g of Adenine to the solution.
Add 0.05 g of L-Arginine to the solution.
Add 0.08 g of L-Aspartic acid to the solution.
Add 0.02 g of L-Histidine to the solution.
Add 0.05 g of L-Isoleucine to the solution.
Add 0.1 g of L-Leucine to the solution.
Add 0.05 g of L-Lysine to the solution.
Add 0.02 g of L-Methionine to the solution.
Add 0.05 g of L-Phenylalanine to the solution.
Add 0.1 g of L-Threonine to the solution.
Add 0.05 g of L-Tryptophan to the solution.
Add 0.05 g of L-Tyrosine to the solution.
Add 0.14 g of L-Valine to the solution.
Add 0.02 g of Uracil to the solution.
Add distilled water until the volume is 1 L.
Combine the appropriate ingredients, and mix in a sealed container. Omit the desired dropout component. Haploid yeast requires a single dropout (i.e., -Trp=-T or -Leu=-L); diploid yeast requires double dropouts (i.e., -Leu -Trp=-LT); and selecting for interactions requires triple dropouts (i.e., -Leu-Trp -His=-LTH, plus 3-AT).
