Preparation
- KOMODO Medium 861.1 sparges Solution A with an 80% N2 and 20% CO2 gas mixture to pH below 6, dispenses it under the same gas atmosphere into serum vials, and autoclaves it.
- KOMODO Medium 861.1 prepares Solutions B and F under 80% N2 and 20% CO2 and prepares sterile Solutions C, D, and E under 100% N2; Solutions D and F are sterilized by filtration.
- KOMODO Medium 861.1 completes the medium by adding appropriate amounts of Solutions B to F to sterile Solution A in sequence.
- KOMODO Medium 861.1 final pH should be 7.0-7.2.
