Preparation
- The vitamin K1, haemin solution and the cysteine are added after the medium has been boiled and cooled under CO2. Adjust pH to 7.2 using 8 N NaOH. Distribute under N2 and autoclave.
- Dissolve 50 mg haemin in 1 ml 1 N NaOH; make up to 100 ml with distilled water and filter sterilize. Store refrigerated.
- Dissolve 0.1 ml of vitamin K1 in 20 ml 95% ethanol and filter sterilize. Store refrigerated in a brown bottle.
