| - | | + | We spent today looking at our filamentous cells under the microscope. |
| - | ==Aims==
| + | |
| - | Since we have recently had problems with both PCR and restriction digests, we set up positive controls to ensure that there is nothing wrong with any of our enzymes or ...

| - | ==Discussion==
| + | |
| - | Worked correctly.. nothing is wrong with our enzymes.. in the case of our ''rocF'' plasmid PCRs, it must be the primers which are the problem.. new ones are supposed to be arriving today.. in the other cases, repeat..

| - | ==Starch plating==
| + | |
| - | | + | |
| - | ===Aims===
| + | |
| - | | + | |
| - | Yesterday we replica plated ''Bacillus subtilis'' 168, that were transformed on Wednesday, onto starch plates.
| + | |
| - | Today we aim to see whether or not the transformed ''Bacillus subtilis'' can breakdown starch. If they cannot break down starch there will be no halo when we test with iodine.
| + | |
| - | | + | |
| - | ===Materials===
| + | |
| - | | + | |
| - | *Starch plates
| + | |
| - | *Pipette tips
| + | |
| - | *Iodine
| + | |
| - | | + | |
| - | ===Results===
| + | |
| - | | + | |
| - | Unfortunately our colonies had halos. Although the insert has integrated, the colonies have antibiotic restistance, the insert has not integrated at the ''amyE'' locus.
