| Product description: | 143B cell line lacking mitochondrial DNA and oxidative phosphorylation. Auxotrophic for uridine and pyruvate. Can be used for generation of transmitochondrial cybrids, control in experiments studying mtDNA contribution to tumor initiation, promotion, malignant conversion, and progression. |
|---|---|
| Gender: | Female |
| CRISPR: | No |
| Conditional: | No |
| Production details: | Prolonged incubation with an inhibitor of mtDNA replication followed by cloning |
| Additional notes: | Cells rely exclusively on glycolysis for their growth. Therefore, they tend to consume glucose faster than their WT counterparts, acidify the medium faster, and die as soon as they consume all glucose. Therefore, do not allow excessive medium acidification (an indicator of glucose depletion) and do not grow cells to high densities |
| Parental cell line: | 143B |
| Model description: | Lacks mitochondrial DNA and all genes encoded there |
| disease: | Mitochondrial Disease |
| Initial handling information: | Upon arrival, store the vial in liquid nitrogen. Quickly thaw the vial in a 37C water bath, transfer vial's content into a 15-ml centrifuge tube containing complete growth medium, pellet cells by centrifugation, remove the medium, resuspend the cells in 10 ml of prewarmed complete growth medium, transfer to 100-mm TC-treated petri dish, incubate @37C+5% CO2. |
|---|---|
| Format: | Frozen |
| Storage conditions: | Liquid Nitrogen |
| Shipping conditions: | Dry ice |
| Growth medium: | DMEM medium with 4.5 g/l glucose supplemented with 10% FBS, 50 ug/ml gentamycin, 50 ug/ml uridine and 1 mM sodium pyruvate |
| Subculture routine: | Do not grow to confluence and do not allow medium acidification. When the growth medium starts changing its color, immediately change the medium or passage cells. To passage, aspirate growth medium, wash with PBS (without Ca++ or Mg++), aspirate PBS, add 0.05% Trypsin in PBS, incubate @37C, 5% CO2 for 5-10 min, tap the vessel to dislodge cells, neutralize trypsin by adding 5 volumes of complete growth medium, disperse cells by trituration, plate 1:4 to 1:10 dilution |
| Atmosphere: | 5% CO2 |
| Storage medium: | (DMEM medium with 4.5 g/l glucose supplemented with 10% FBS, 50 ug/ml gentamicin, 50 ug/ml uridine and 1 mM sodium pyruvate)=45% + (Heat-inactivated newborn calf serum)=45% + 10% sterile DMSO |
| Recommended controls: | WT 143B cells |
