lab 208

Main purpose

• Colony PCR for HAO
• USER reaction

Who was in the lab

Kristian, Julia, Natalia, Henrike

Procedure

Gels

Run 1% agarose gel on colony PCR products. The samples are named:

• HAO 1
• HAO 2
• HAO 3
• HAO 4
• HAO 5
• HAO 6
• HAO 7
• HAO 8

Samples 1-5 and 8 were top10 transformant colonies. Colonies 1-5 were small (1mm wide) more condense and more difficult to collect; this may be due to the proteins expressed on the membrane that make it thicker. Colony 8 was wider (3mm wide) and more sticky. Samples 6 and 7 are normal transformant colonies.

Colony PCR

To check HAO transformants from USER cloning on the 01.08.

Nanodrop

Measured Midiprep from 03.08.. No DNA was detectable in the samples. Redo purification.

PCR

PCR for araBAD with new RV primer, SPL (synthetic promoter library) in pZA21 and reference promoter in pZA21.

samples:

• ara1, ara 2 - primers 12a + 12bn, template K808000, 57C, 1:00
• spl1, spl2 - primers 52a + 52b1, template RFP in pZA21, 54C, 2:30
• ref1, ref2 - primers 52a + 52b2, template RFP in pZA21, 54C, 2:30

USER reaction

Performed USER reaction with cycAX plus his-tag and pZA21 after standard protocol SOP1.
