- | ==Use of Antibiotic Stocks==
| |
- |
| |
- | Stocks are to be kept in a -20<sup>o</sup>c freezer, clearly labelled.
| |
- |
| |
- | Available stocks in the lab are:
| |
- | *Ampicillin 100mg/ml , 1ml in each eppendorf
| |
- | *Chloramphenicol 25mg/ml , 200µl in each eppendorf
| |
- | *Kanamycin 50mg/ml , 1ml in each eppendorf
| |
- | *Erythromycin 10mg/ml , 1ml in each eppendorf
| |
- |
| |
- | ===To make plates:===
| |
- |
| |
- | Put one entire tube into 1 litre of LB AGAR - This should be done in the flow hood.
| |
- |
| |
- | This will make the ''standard plates''
| |
- | *Ampicillin 100µg/ml
| |
- | *Chloramphenicol 5µg/ml
| |
- | *Kanamycin 50µg/ml
| |
- | *Erythromycin 5µg/ml
| |
- |
| |
- | To make these concentrations in the standard 250ml bottle LB Agar, add:
| |
- | *250µl ampicillin stock
| |
- | *50µl chloramphenicol stock
| |
- | *250µl kanamycin stock
| |
- | *125µl erythromycin stock
| |
- |
| |
- | ===Common plate concentrations for backbones:===
| |
- |
| |
- | *pSB1C3 (''E.coli'') : 25µg/ml Chloramphenicol
| |
- | *pSJ150 (''E.coli'') : 100µg/ml Ampicillin
| |
- | *pSJ150 (''B.subtilis'') : 5µg/ml Chloramphenicol
| |
- | *pSB1K3 (''E.coli'') : 50µg/ml Kanamycin
| |
- | *PSB4K5 (''E.coli'') : 50µg/ml Kanamycin
| |
- |
| |
- | ===To make liquid cultures===
| |
- |
| |
- | Check for specific concentrations, this is usually lower than the ones you use for plates, and add the required amount to sterile LB.
