Practice GFP Assay - Does it glow at all?

1) Stat a single colony of 186W from 7.14.09 replate. Started at 11 am

2) reached OD of 0.2 at 3 Pm. Put paraoxan to final concentration of 1 mM

3) dilute 3.6 ml of 100 mM in MeOH with 3.6 ml of dH2O

Final [] of stock is 50 mM in 50% EtOH

-dilute 1ml final [] 20 mM

added 0.4 ml 50 mM stock, 0.6 ml dd H2O

-> final is 20% MeOH 20mM

-put 50 ul 20 mM stock into 950 uL culture (OD = 0.2)

- incubate starting at ~ 4PM. Pick it up at 6 PM (generally, allot 2 hours of incubation time)

- looked under microscope. Result = NO GFP IN FIRST TRY

-Replated his - Paraoxan Biosensor colonies. 3-4 colonies/plate.

-put into incubator

- need to replate Kan - Paraoxan plates tomorrow. Can already see lots of cells

Transformations of Longtine PCR Products into Yeast

Transformed products into yeast, however accidentally used Uracil plates instead of -HIS plates for products 1-3. Transformations were unsuccessful for 4 and 5. Beads may spread cell too thinly. Pipet shearing may have also been a cause.
