    GeneTV how to view Southern Report
  • How come I didn’t get a Southern report after I entered my probe?

    Below are some of the reasons if a Southern report is not generated after you have designed your probe:

    • An incorrect probe type was selected for your probe sequence.
    • An external probe that was located >10kb outside the region flanking the 5’ or 3’ arm.
    • If you selected self-designed as your probe type, then there is no Southern report.
  • What is the difference between Project Report and Client Report?

    Project Report displays sequences for the forward and reverse strands for your project of interest. Client Report displays only sequences for the forward strand (5’->3’) for your project of interest. Sites of restriction enzymes are indicated only in the Project Report. 5’ and 3’ retrieved homology arms, insertion sites of vector components, locations of oligos, probes, exons, repeats, etc. are annotated in each report.

    Note if the sequence is >60kb, the report will not be displayed especially for BAC targeting constructs.

  • What is the difference between WT and TV on Project Report and Client Report?

    WT displays wild-type genomic sequences before modifications. 5’ and 3’ retrieved homology arms and locations of probes, exons, and repeats are indicated. TV displays sequences after modifications including annotated sequences of 5’ and 3’ retrieved homology arms, vector components, selection cassette, locations of oligos, probes, exons, repeats, etc.

    Note if the sequence is >50kb, the report will not be displayed especially for BAC targeting constructs.

  • What is displayed on the schematic diagram?

    The title of the schematic diagram is displayed on the top with the gene name (i.e. Apoe), the project ID# (i.e. CSD34293), and the targeting vector name (i.e. PG00159_Z_7_B12).

    Three images are shown on the diagram. The first image (WT) displays the wild-type genomic sequences with boxes as exons and color-coded lines for 5’, 3’, and middle arms. The second image (Vector) displays the vector components without the vector backbone. Flags are used to indicate FRT or loxP sites and boxes are used for cassettes. The third image (KO) shows the targeting vector integrated into the genome. The WT sequence is replaced by the targeting vector.

    Legends of symbols and colors used in the diagram, lengths of the retrieval arms and vector components, and pertinent information about your selected project are provided below the diagram.
