PROJECT LAB BOOK

Welcome to the Macquarie University project lab book page!

Here you will find a day-by-day account of our triumphs and failures.

A day-by-day progress for Agrobacterium Tumefaciens Bacteriophytochrome

20th August 2010

Genomic DNA extraction

  • A. tumefaciens genomic DNA extracted using the Invitrogen PureLinkTM Genomic DNA Purification kit as per the manufacturer’s protocols.

  • The extractions were run on a GelRed stained 1% agarose gel and photo taken for visualization (see below).

  • A NanoDrop spectrophotometer reading was also recorded to check the quality of the extracted genomic DNA.

  • The extraction was successful for all A. tumefaciens cell lysate samples (labeled DNA1.1, DNA1.2, DNA2 (See figure below)

    • A. tumefaciens genomic DNA extraction agarose results:

    All four DNA samples show a smear of gDNA. Because the samples were treated with RNase there is no band indicative of RNA visible = SUCCESS!

    ***** Results of A. tumefaciens genomic DNA extraction ***

    Figure 1. GelRed stained 1% agarose gel of genomic DNA extraction from A. tumefaciens.

    In lanes 1 and 11 there is a 1kb ladder. In lane 2 is the DNA1.1 flow through, lane 3 is the DNA2.2 flow through, lane 4 is the DNA2.1 flow through and lane 4 in the DNA2.2 flowthrough. All four samples show a smear that is indicative of genomic DNA. The extraction has been successful.

    Nanodrop absorbance readings:

    Genomic DNA sample 260/280 OD ratio Concentration (ng/mL)
    DNA1.1 1.88 351.5
    DNA1.2 1.98 203.1
    DNA2.1 2.14 738.9
    DNA2.2 2.16 709.7

    Overall, the Nanodrop readings show that we have obtained good DNA concentration with minimal protein contamination

    = SUCCESS!

    Primer design

  • Various primers were designed manually and using Primer 3 Software package for PCR amplification.

  • The primers were ordered and supplied through XXXXXXXXXXXXXXXXX.

  • There was an array of various primers ordered for amplification of different products. The details of the primers are described below.

    • Fwd and Rvs primers for amplification of the full length A. tumefaciens BphP gene:

    Primer name Primer Sequence
    F1 (AT-FWD-1) 5’-ATG AGT TCA CAT ACG CCG-3’
    R1 (AT-RVS-1) 5’-TCA GGC AAT TTT TTC CTC-3’
