Preparation
- Mix PPLO Broth w/o CV, Tryptone, Sorbitol, and Distilled water as the basal medium.
- Adjust the basal medium to pH 7.5.
- Autoclave the basal medium at 121 C for 15 minutes.
- Filter-sterilize the serum, yeast extract, sugar, arginine HCl, and phenol red additions.
- Aseptically add the filtered stocks to the sterile basal medium.
