18.10.2009 (Group 2) 1.Directly testing the oxygen promoter in the presence or absence of oxygen.We have prepared 4 set of tubes in the presence or absence of oxygen and we compared the growth of bacterias by using spectrophotometer. OR, testing the hemoglobin activity; we thought that if the gene coding for hemoglobin is working it means that our oxygen promoter is also working. (Group 1) 2. Centrifuge of supernatant + ammonium sulfate, 14000 rpm for 30 minutes. 3. Preparation of potassium phosphate buffer ( pH 6.6) 4. Resuspend the pellet in potassium phosphate buffer, 5ml,0.1 M and pH 6.6 5.Dialyzing them (Lard, Lard + ABC and Only top 10) in a nitrocellulose tube at 4 centigrade degrees in 500 microliter potassium phosphate buffer stirring for overnight.
