The concentration of the Hag-Flank-construct was too low (c = 5.8 ng/µL) to use it for the ligation into pMAD. A PCR has been run to increase the amount of the construct.

The PCR-product has been checked on a agarose gel (3 µL + 1 µL 6x Loading-Dye)
Expected band: 2000 bp is there, but also 2 additional bands
A band with the expected size of ca 2000 bp is visible but there are also two additional DNA-fragments with a lower size. The rest of the PCR-product (47 µL) has been separated on a gel and the expected DNA-fragment has been excised and purified with the Gel Extraction Kit. The purification led to a concentration of 45 ng/µL.
