Serum free DMEM and RPMI media 500 ml DMEM with L-glutamine, or 500 ml RPMI-1640 with L-glutamine 5 ml MEM nonessential amino acids (100x, 10 mM) 5 ml HEPES Buffer (1 M) 5 ml L-glutamine (200 mM) 0.5 ml 2-mercaptoethanol (5.5 x 10-2 M) | | | Mix all the ingredients in a biosafety cabinet with either DMEM or RPMI media depending on your need. Filter sterilize the media by passing through a 0.22 µm vacuum filtration system. |
| Complete RPMI and DMEM media | | | Add 50 ml of heat inactivated fetal calf serum to serum free RPMI or DMEM media to obtain complete media. |
| MACS buffer | | | Add 2 ml of 0.5 M EDTA and 10 ml of heat inactivated fetal calf serum to 500 ml of Phosphate-buffered saline (PBS, Ca2+ and Mg2+ Free, pH 7.2) and 2 µg/ml 2.4G2 (Fc-Block antibody). |
| FACS staining buffer | | | Dissolve sodium azide to 0.05% (0.25 g per 500 ml) in MACS buffer to obtain FACS staining buffer |
10x Collagenase D and DNase 1 stock solution
Dissolve 1 g of collagenase D and 0.2 ml of DNase 1 stock (1 mg/ml, 100x) in 20 ml of PBS containing Ca2+ and Mg2+ to obtain a solution of approximately 1,000-2,000 Units of collagenase activity per ml. | | | This 10x stock solution can be prepared ahead of time and stored at -20 °C for several weeks. Dilute 1 ml of this with 9 ml of serum free RPMI immediately before use. |
