Dictyostelium Predation Assay for transposon mutagensis of pDR2 Part(1)

Date: Nov./1/2014
The protocol in the link
Plate name :  pDR 2/Tetra. transposon mutagensis.
 The result: after 4 days incubation at room temp. in a dark place

Plaques in Kleb. plate=35 plaques in dilution 1/1000 (-3)

Plaque forming unit pfu =# plaque X dilution factor/volume of inoculum
                                       35 X10^3/10 = 3.5 X10^3
2 μl of  8 Dicty. dilutions that contain(7.0 X 10^3, 7.0 X 10^2, 7.0 X 10 ,7.0 , 0.7,....) Dicty. cells were used on sm2 agar in four replicate for each dilution.
The result after 4 days :
