IGEM:IMPERIAL/2006/LabCalendar/2006-9-2

 TO DO: *Testing of T9002, J37016, J37020, S01656, J37015, J37015RS *Culture up J37022 and J37025 from plates in incubator for mini & maxi on Sunday *Move 3 plates (2 Rosetta and 1 BL21) into cold room

Testing of T9002, J37016, J37020

 * Reported PROBLEM: After the 2hrs shake of the 16mL cultures, the OD of the T9002 assay was still at about 0.1. So all of the present culture was diluted further into 25mL.
 * 5mL tubes put into shaker for 4hrs at 13:15
 * Taken out of shaker at 17:20
 * OBSERVATION: Both cultures of J37016 & J37020 looked very transparent, whereas T9002 was very "milky" (high OD). Was the OD read correctly when diluting into 25mL ?


 * Pipetting into 96 well plate
 * PROBLEM: There was not enough cell culture in some of the 5mL tubes to fill all 8 repeats of the wells. There was only about 1.5mL culture in some of the tubes. In others, there was about 1.8mL. Why?


 * Fluorescence reading in Biochem (18:00)
 * Results:
 * T9002 shows a slight increase of flurescence with AHL increase (however, it is a line, not reaching saturation)
 * J37016 do show the expected response, however, a sudden trough can be seen in at [AHL]=1nM
 * J37020 no change in fluorescence, apart from a trough at [AHL]=7nM
 * See results page for data

Culturing J37022 and J37025

 * Cultured J37022 and J37025 from plate for mini and maxiprep tomorrow
