Plasmid mini-prep for Part1-7

Cryo-Stocks of E. coli transformants (C1, parts 1 – 7):

·         900 μl E.coli ON culture + 100 μl DMSO 100% in special tubes (ask Katrin or Katrin^^)

·         vortex

·         store at – 70 °C (red box)

Backup plates:

Storage at 4 °C

 

Plasmid Mini-Preparation of parts 1 - 7:

ON cultures of C1 for parts 1 – 7 with kit “NucleoSpin? Plasmid” von Macherery-Nagel according to manual pp. 16-17 (NucleoSpin? Plasmid protocol for purification of high copy plasmids)

Step 5: recommended washing of silica membrane with buffer AW was performed

Step 7: Elution with buffer AE pre-heated to 50 – 60 °C (in future: DON’T elute with this buffer, use pre-heated HPLC-H2O instead! No one knows what’s inside the buffer and its components (EDTA?) could interfere with sequencing and other reactions)
