Both samples 1 and 3 had a band slightly above the 3000 bp band, which was probably the 3200 bp vector. In addition, both samples 1 and 3 had a band slightly above the 700 bp band, which was likely the 705 bp plasmid. Overall, there is evidence to conclude that Sample 1 is the cloned plasmid DNA because of its similarities to the control DNA. Sample 2 had no bands of any sort and there was likely no DNA there in the first place due to a bad miniprep. Sample 1 was submitted for DNA sequencing to confirm that it is in fact the cloned plasmid DNA.

Extraction and Verification of mCh

  • Name: mCh / BBa_J176005
    • Date of culture inoculation: 10/17/13
    • Results for Cultures 1 and 2: Mixture is cloudy so growth in both. Success.
    • Results for Streaks 1 and 2: Growth in both areas along zig-zag line, although more growth in colony 1 streak than colony 2 streak. Overall success.
  • Sample 1: mCh/V0120 colony 1; BBa_J176005; part = 705 bp; vector = 3200 bp
  • Sample 2: mCh/V0120 colony 2; same
  • Sample 3: mCh/V0120 (control DNA); BBa_J176005; part = 705 bp; vector = 3200 bp

In addition, both samples 1 and 3 had a band slightly above the 700 bp band, which was likely the 705 bp plasmid.

DNA Sequencing Samples

  • Submitted to DNASU on: '10/21/13'
  • Order Number: 8258
  1. mCh - forward primer 'P0001' -- 705 matches, thus 100% matching across the sequence. DNA cloning successful.
  2. mCh - reverse primer 'P0002' -- 705 matches, so 100% match. DNA cloning successful.
