Ordered DNA stocks

The DNA from Mr Gene has finally arrived, now we're ready to build some biobricks!

We were so excited; we immediately dissolved the DNA in water and performed a transformation with 100 ng of the DNA and plated on the LB agar containing the appropriate antibiotic.

Characterization of Anderson RBS sequences

Yesterday's purified PCR product of I13401 and the Anderson RBS Biobricks (J61100, J61101, J61107, J61117 and J61127) were digested:

# Sample Enzyme 1 Enzyme 2 Buffer BSA Needed fragment
C1 1.15 μg J61100 SpeI PstI 2 (BioLabs) ‘S–J61100 pSB1A2–P’
C2 1.68 μg J61101 SpeI PstI 2 (BioLabs) ‘S–J61101 pSB1A2–P’
C3 1.30 μg J61107 SpeI PstI 2 (BioLabs) ‘S–J61107 pSB1A2–P’
C4 0.95 μg J61117 SpeI PstI 2 (BioLabs) ‘S–J61117 pSB1A2–P’
C5 0.51 μg J61127 SpeI PstI 2 (BioLabs) ‘S–J61127 pSB1A2–P’
D1 2.59 μg I13401 XbaI PstI 2 (BioLabs) ‘X–I13401–P’
D2 2.65 μg I13401 XbaI PstI 2 (BioLabs) ‘X–I13401–P’

The digestion products were purified using Roche's PCR Purifiation Kit and loaded onto a 1% agarose gel for comparison with the non-digested BioBricks:

1 % agarose of digestion check. Gel runned 1 hour at 100 V. Of all samples 1 μL sample + 4 μL MQ + 1 μL loadingbuffer was loaded and 5 μL was loaded of marker

6 negative control 123 μg ‘S–J61117 pSB1A2–P’ - 15 μL

To all samples one-tenth of the total volume ligase buffer was added.

Emulsifier

Pieter is testing different condition for the emulsifying Assay. To determine the emulsifying activity we set up a calibration curve with SDS. He prepared the following samples:

# Hexane (mL) Tris Buffer pH 8 (mL) 10% SDS (mL)
B 1 1.1 0
100 1 1 0.1
50 1 1.05 0.05
25 1 1.075 0.025
10 1 1.09 0.01
5 1 1.095 0.005

Kampioenen!!!!

Today the Dutch team will play the semi-final of the World Cup! Hear us cheer! Stop sound

Pieter by the BBQ
We are ready for the soccer game
the Netherlands won the semi-final!
