Method for making and using cold atmospheric plasma stimulated media for cancer treatment
A method for preparing cold atmospheric plasma stimulated cell culture media with a cold atmospheric plasma system having a delivery port out of which an inert gas flows. The inert gas may be helium. The method comprises the steps of placing a cell culture media in a first well, the first well having a bottom and having a diameter greater than 20 mm; wherein the cell culture media placed in the first well has a volume of 4 ml or less, treating the cell culture media in the first well with cold atmospheric plasma, wherein the treating is performed with a gap between the delivery port and the bottom of the first well is between 2.5 cm and 3.5 cm, and transferring a portion of the treated media to cultured cancer cells in a second well. The cold atmospheric plasma may be applied for 0.5 minutes to 2 minutes.
1. A method for preparing stable cold atmospheric plasma stimulated cell culture media with a cold atmospheric plasma system having a delivery port out of which inert gas flows, the method comprising the steps of:
placing a cell culture media in a first well, said first well having a bottom and having a diameter greater than 20 mm; wherein said cell culture media placed in said first well has a volume of 4 ml or less, said cell culture media comprising an amino acid solution not having cysteine or tryptophan;
treating said cell culture media in said first well with cold atmospheric plasma, wherein said treating is performed with a gap between said delivery port and said bottom of said first well is between 2.5 cm and 3.5 cm; and
applying a portion of said treated media to cancer cells.
2. The method according to claim 1 wherein said gap is 3 cm.
3. The method according to claim 1 wherein said step of treating said cell culture media comprises applying cold atmospheric plasma to said cell culture media for 0.5 minutes to 2 minutes.
4. The method according to claim 1 wherein said step of treating said cell culture media comprises applying cold atmospheric plasma to said cell culture media for 1.5 minutes or longer.
5. The method according to claim 1 wherein said cell culture media further comprises Dulbecco's modified Eagle's medium (DMEM).
6. The method according to claim 1 wherein said media further comprises Dulbecco's modified Eagle's medium (DMEM) supplemented with 10% (v/v) fetal bovine serum (FBS) and 1% (v/v) antibiotic (penicillin and streptomycin) solution.
7. The method according to claim 1 wherein said cell culture media placed in said first well has a volume of 2 ml or less.
8. The method according to claim 1 wherein the inert gas comprises helium from which the cold atmospheric plasma is formed is helium.
