agarose gel electrophoresis

13.07.2012

Topic: gel electrophoresis of the pcr product

Investigators:Xenia and Mario

Aim:gel electrophoresis of the pcr product (12.07.2012)

material and method:

gel electrophoresis

samples:

- 4 µL dest. Wasser + 1 µL pcr sample + 1 µL loading dye

Results:

The fragment should have the size of 2000 bp, but the band is by 3000 bp

Further Tasks:

test digestion

2012-17-07

Topic: test digestion

Investigators: Tobias

Materials:

pcr products of 02-07 and 12-07-2012 (Ta= 70°C)

restriction enzymes (FastDigest XbaI, PstI)

Method:

digestion: 10 µL DNA + 1 µL of each enzyme + 2 µL green-buffer + 17 µL water

Results:

caused on the gel qualtity: repetition of the digestion

Further Tasks:
