Indigoidine production with pKH1 II (Konrad)

fragment amplification

==> f1: bpsA (all)

• 14.6 µl H2O
• 25 µl Phusion Flash
• 2x 0.5 µl Primer (NI01,NI06)
• 0.4 µl template pMM64

Gel purification (50µl): by accident did not take 3 but 1 Volume buffer QG

Labelling fragements: 1 I and 1 II (from different lanes)

fusion PCR

==> for fusion of both fragments bpsA and svp using Phusion Flash HF

• 19.8 µl H2O
• 25 µl Phusion Flash MM
• 2x 1.0 µl Primer (NI01,NI08)
• 2.6 µl template (f1:bpsA)
• 0.6 µl template as 1:10 dilution (f6:svp)

Gel purification (50µl): by accident did not take 3 but 1 Volume buffer QG

Labelling fragments: 1 I and 1 II (from different lanes)

Amplification pSB1C3 (f7)

==> f7: pSB1C3 (linear.) with our Phusion MM and Phusion MM of SYNtheSYS (old, don't know if functional...)

(add items in this order)

• 14.6 µl H2O
• 25 µl Phusion MM
• 2x 0.5 µl Primer (NI09,NI10)
• 0.4 µl template (pSB1C3 with J04450 (pJM03))

-->Hot start

RESULT: no product neither with Synthesys fusion nor our fusion

==> f7: pSB1C3 (linear.) with Fusion Flash

(add items in this order)

• 14.6 µl H2O
• 25 µl Phusion Flash
• 2x 0.5 µl Primer (NI09,NI10)
• 0.4 µl template (pSB1C3 with J04450 (pJM03))

fusion PCR

==> for fusion of both fragments bpsA and svp using Phusion Flash HF

• 19.8 µl H2O
• 25 µl Phusion Flash MM
• 2x 1.0 µl Primer (NI09,NI10)
• 5 µl template (f1:bpsA I,03.07.13)
• 0.6 µl template as 1:10 dilution (f6:svp)

--> wrong primers, should have taken NI01 and NI08
--> more than 50µl as not enough bpsA template was left

Re-PCR of fusion (bpsA+svp)

==> for amplification of fusion fusion product 03.07 (bpsA + svp) using Phusion Flash HF

• 18 µl H2O
• 25 µl Phusion Flash MM
• 2x 1.0 µl Primer (NI09,NI10)
• 5 µl template (fusion bpsA+svp,03.07.13)

--> wrong primers, should have taken NI01 and NI08

Re-PCR of fusion (bpsA+svp)

==> for amplification of fusion fusion product 03.07 (bpsA + svp) using Phusion Flash HF

• 19 µl H2O
• 25 µl Phusion Flash MM
• 2x 0.5 µl Primer (NI01,NI08)
• 5 µl template (fusion bpsA+svp,03.07.13)

Preparations

• prepare liquid cultures of TOP10 + pMM64/65 for minipreps: 3 ml TB + Amp/Kan
• prepare liquid cultures for induction test: 3 ml LB + appropiate AB
  • BAP1
  • BAP1 + pMM64 (Amp)
  • BAP1 + pMM64 + pMM65 (Amp + Kan)
  • TOP10 + pJH1 (Kan)

Re-PCR of fusion (bpsA+svp)

Ralf

PCR from glycerol stock S. lavendulae with Fermentas; Thermoscientific and NEB Taq 50 ul

• MM 25 ul, 7,5 ul primer RB7/8 100 mM, 5 ul water, 5 ul culture

• S. verticillus and S lavendulae in 50 ml YEME medium for 46 h at 28 °C.
• filamentous growth and spherical colonies in S. lavendulae flask after 1 day -> contamination?!
• no growth in S. verticillus flask after 18 h
• prepare plates
