Streak colony transforman and Cryo Preservation

Today, early in the morning I streak colony from desired-putative recombinant into another petri-dish, so in the evening they could be inoculated into 5 ml LB containing appropriate antibiotic for plasmid isolation tomorrow.

I got enough putative clone especially from PPICZalpha-AO6 and AO5, except for PPICZB-GFP EcoRi and PPICZalpha-AO1. I remember the latter of two, its vector came from different source. AO5 and AO6 I got by myself. however, we cannot sure until we digest to verify desired clones.

I usually make LA+kanamycin (50 ug/ml) for recombinant E.coli containing kanamycine resistance. for example we we want to use 300 ml of LA we must put 300 ul kanamycine from stock 50 mg/ml.

I also streak e.coli recombinant for cryopreservation I got from my previous experiment as follows:

1. pOKT-kan4R

2. pOKT-GFP+S (EcoRI)

3. pOKPldhSlpA-AO1

4. pOKPldhSlpA-A05

5. pOKPldhSlpA-A06

In the evening, it’s about 3.30 pm I prepare for inoculating putative recombinant that I have streak early this morning ( we select 6 of each petri dish representing all of clones) for plasmid isolation tomorrow.

some previous clones must be refresh today:

1. pGEMT ICPPFN

2. pAS900

3. pGEMTGFPUV+S1

4. pOKT-GFPUV+S1

5. pOKT-GFP+S (EcoRI)

Zeocin (25 ug/ml) in 5 ml LB, so we have to add 2.5 ul Zeocin from stock 100 mg/ml.
