PCR were performed as follows:

mastermix:

MQ: 93.6µl

10xbuffer: 12.0µl

dNTP's: 2.4µl (each 10mM)

Phusion: 1.2µl (Pfu-Promega)

->109.2µl/6 = 18.2µl each tube

-> no products on gel picture

8-10-2010

PCR were performed with pdu-template:

mastermix:

template: 0.5µl

primer fwd/rev: 1µl

MQ: 15.88µl

10xbuffer: 5µl

DMSO: 0.625µl

dNTP's: 0.5µl (each 10mM)

Phusion: 0.4µl (Pfu-Promega)

25µl

->109.2µl/6 = 18.2µl each tube

this mix was produced for all of the six primer pairs (see 9.8.10)

->again no spcific product was seen on the gel picture

Preparing Competent Cells with Benny's protocoll & buffers

- grow the culture to an OD ₆₀₀ of ~ 0,3

-> our cells: OD ₆₀₀ = 0,256

- centrifuge for 10 min at 4°C at 3000rpm

- resuspend the pellet in buffer 1

-> we used 400 µl

- centrifuge for 10 min at 4°C at 2500rpm

- resuspend the pellet in less buffer 1 than before

-> we used 200 µl

- add buffer 2 in a ratio of 1:10 = buffer 2:buffer 1

-> we added 20µl of buffer 2

- incubate on ice for 10 min

-> as we probably used too little buffer, we added another 200 µl of buffer 1 and 20µl of buffer 2

- aliquote the suspension and shockfreeze it at -80°C

-> we put 50 µl in each eppendorf

Test-Transformation in order to see whether the cells will work

- done with protocoll (3 Transformation)

-> we tested with the following DNA:

1. K098200 (biobrick) [Amp., 5 µl]

2. pUC [Amp., 1µl]

-> as the cells are probably in a to high concentration, we thined them down with saline to an end-concentration of 10 ^-2

8-25-2010

again: Preparing Competent Cells with Benny's protocoll & buffers

- grow the culture to an OD ₆₀₀ of ~ 0,3

-> our cells: OD ₆₀₀ = 0,22

- centrifuge for 10 min at 4°C at 3000rpm

- resuspend the pellet in buffer 1

-> we used 16 ml

- centrifuge for 10 min at 4°C at 2500rpm

- resuspend the pellet in less buffer 1 than before

-> we used 2 ml

- then we allocated the suspension into two eppendorfs

- in eppendorf + we added buffer 2 in a ratio of 1:20 = buffer 2:buffer 1

-> we added 50µl of buffer 2

- incubate on ice for 10 min

- aliquote the suspension and shockfreeze it at -80°C

-> we put 50 µl in each eppendorf

Test-Transformation in order to see whether the cells will work

- done with protocoll (3 Transformation)

-> we tested with the following DNA: pUC (10pn/µl, Amp) 1 µl was used

therefore we made fresh pUC (10pn/µl): 0,5 µl pUC-stock (0,5µg/µl) + 25 ml H₂O)
