Purification of PCR products of the three sensing constructs
-I purified the PCR products from the previous Day and the concentrations were within an acceptable range. Since I had not yet amplified the constitutive promoter from iGEM I put the purified Backbone for this promoter into the refridgarator for late use.

DpnI digest of the two pH sensitive promoters and their backbones
I did a DpnI digest and measured the concentrations again, they were all around 50ng/ul which is good.

Gibson assembly of the two constructs with the hya and the cad promoter (pH-sensors)
I did a Gibson assembly of both sensing construcst but it did not work for the one with the hya promoter, so I did another Restriction digest of the purified PCR products for this promoter.

PCR of the MMP2 insert and its Backbone and the MMP9 Backbone
We did a PCR of the backbones for both MMP2 and MMP9 as well as of the insertMMP2. The Gel showed that it worked.
