- | <p>PhaP-1 and PhaP-2 plates showed colonies!!
| |
- | A colony from each plate was picked and used to infect 1ml LB+Kan. Liquid cultures of PhaP-1 and PhaP-2 were grown for 6 hours at 37°C 220 rpm and then used to prepare glycerol stocks. Remaining liquid cultures were re-filled with 5 ml LB+Kan an grown ON at 37°C 220 rpm for tomorrow MiniPrep.
| |
- | Glycerol stocks of PhaP-1 and PhaP-2 are stored at -80°C in the <i>iGEM 2010 Registry</i> box.
| |
- | </p><p>Ligations were heated at 65°C for 5 minutes to inactivate ligase ad then tranformed in E. coli TOP10 home made competent cells. Plates were incubated ON at 37°C (we decided to incubate plates 5 hours longer than usual, because cell growth was already slower for I6).

- | <p>All plates showed colonies after 19-hour growth at 37°C!!

| |
- | <ul><li>I7: small green colonies with satellite colonies were observed. Negative colonies are present and can be easily distinguished, because they are red.
| |
- | </li><li>I8: green colonies were observed, few negative colonies are pink.
| |
- | </li><li>I9: big colonies were observed, some of them are surrounded by satellite colonies.
| |
- | </li><li>I10: big colonies were observed, some light pink colonies are present, surrounded by satellite colonies.
| |
- | </li></ul>
| |
- | <p>These results are encouraging, because they are consistent with our expectations: ligations provide a high metabolic burden to the cell, so growth is slower. <i>Positive</i> green colonies are smaller and not surrounded by satellite colonies. <i>Negative</i> colonies are bigger and surrounded by satellite colonies, confirming that they had a faster growth than our ligations!
