We do a mini-prep of E1010, "F1610" and P0140

E1010/F1610
Yesterday we found out that F1610 has a size of 300bp, instead of 800bp. So there are two hypotheses: 1) The mini-prep is bad or 2) the biobrick from IGEM is bad.

So we do another digestion series with EcoRI and SpeI. We do it with different mini-preps of F1610 and with the last mini-prep of E1010 that worked (as a positive control).

Some mini-preps of F1610 haven't enough liquid left, so we do a PCR with these (we use E1010 from the last mini-prep as a positive control).

At the same time we do a PCR of all plasmids that should have E1010/F1610 ligated to see if there is a fragment of 1500 bp.

Result of Gel
All mini-preps of F1610 have a fragment of 300 bp. So the biobrick from IGEM doesn't work. No ligated fragment E1010/F1610 is visible.

(see Gel picture on page 75 in lab notebook)

Test of specific primer of BBs
We do a PCR to see if the specific primers that Alexandre ordered work with our biobricks. We will do the gel tomorrow.
