** Today we received the samples from Team Cultivation & Purification. We are really motivated to measure the activity of our new produced enzymes. But before that we have to prepare the samples. This implied the determination of the protein concentration in each fraction, which we did today. The results are listed in the following table:

*'''Team Substrate Analysis:''' The Massspectrometry data showed two potential products after the Laccase treatment of Estradiol and Ethinyl estradiol but we unfortunatly could not identify them so we decided to do MS-MS on thoose. The products showed that after Laccase treatment both Estradiol and Ethinyl estradiol losses two '''H''' atoms which was new for us.

** Before starting our activity assay we re-buffered the fractions we got from Team Cultivation and Purification. It took some time, that's why we had no time for activity analysis yet. But we prepared everything for the next day, including determining the protein concentration of the fractions after they have been re-buffered. This is what we got:

** Finally the day had come to measure the activity of our own produced laccases. This activity assay should give information about the enzyme content in every fraction. To make the measurements comparable we applied the same protein amount in every sample. Again, we used our [https://2012.igem.org/Team:Bielefeld-Germany/Protocols/Analytics#General_setup_of_enzyme_activity_measurements/ standard activity assay protocol], but this time we used the [https://2012.igem.org/Team:Bielefeld-Germany/Protocols/Materials#Britton-Robinson_Buffer/ Britton-Robinson Buffer] at pH 5. Also we applied 0.1 mM ABTS and measured over night.

** After getting our interesting activity measurement results, we had to figure out which fraction is going to be used in the following experiments and how much laccase it contains besides other proteins. We agreed, that the most active fraction contains 90 % laccase, which is commonly used in the literature. Since we applied the same protein amount of each fraction for the activity measurements, we made sure that the results really correspond to the amount of laccase. These are the most active fractions we have chosen with their contained laccase amount:
+
<ul>
-
*** ECOL: Fraction 50% 2 with a laccase concentration of 63,9 µg mL<sup>-1</sup>.
+
 
-
*** BPUL: Fraction 50% 2 with a laccase concentration of 25,1 µg mL<sup>-1</sup>.
+
<li><b>We did it! About our qualification for the World Championship in Boston</b><br><br>
-
*** BHAL: Fraction  5% 3 with a laccase concentration of 10,9 µg mL<sup>-1</sup>.
+
 
-
*** TTHL: The best fraction of our TTHL laccase was fraction 50% 1 with a laccase concentration of 4,03 µg mL<sup>-1</sup>. In regard to Team Immobilization and Team Substrate Analysis we had to reach a higher amount of TTHL laccase. So we thought of combining two fractions. We chose the second best fraction of TTHL, which is 5% 3. To calculate the amount of contained laccase we had to compare the activity and reconsidered the slope. Since we stated the fraction with its highest activity as 90 % contained laccase, we calculated the amount of laccase regarding to that one. The following figure shows the slopes we got out of the activity from fraction 50% 1 and fraction 5% 3 (which is the second best). Accordingly to this, fraction 5% 3 contains 68,9% of laccase, which is 4,8 µg mL<sup>-1</sup>. In total, the composed fraction contains 4,4 µg mL<sup>-1</sup>.
