BioBricks

On this page, you will find our new designed BioBricks and also our plasmids used in the experiments.

Here you can get an Overview of our BioBricks. If you want to see more details especially for certain BioBricks, you can click on the BioBrick definition and explore the registry entries.

  • BBa_K1470000: mCAT-1

    mCat-1 is the receptor we introduced to human cells to be able to infect them using the MuLV. The first of our favorite parts! :)

  • BBa_K1470001: Puromycin N-acetyl-transferase (PAC)

    Puromycin N-acetyl-transferase is an enzyme which we used for selecting stable eucaryotic cell lines. Because of the blocked protein biosynthesis more than 99% of uninfected cells will be dead within two days.

  • BBa_K1470002: Galactose-induced gene 4 (Gal4BD)

    Galactose-induced gene 4 (Gal4BD) is used to investigate gene expression levels.

  • BBa_K1470003: Woodchuck Hepatitis Virus Posttranscriptional Regulatory Element (WPRE)

    Woodchuck Hepatitis Virus Posttranscriptional Regulatory Element (WPRE) is a regulatory RNA sequence, which promotes viral gene expression.

  • BBa_K1470004: Secreted Alkaline Phosphatase (SEAP)

    Secreted Alkaline Phosphatase (SEAP) is used in cell culture assays to quantify gene expression. The second of our favorite parts! :)

  • BBa_K1470005: engineered PDZ domain (ePDZ)

    engineered PDZ domain (ePDZ) is an important part of the blue light system.

  • BBa_K1470006: The Viral Vector (pMIG)

    The Viral Vector (pMIG) is the plasmid which is used to tranfect Phoenix cells with the gene to be packed into viral particles. It contains two LTRs and a multiple cloning site. The third of our favorite parts! :)

  • BBa_K1470007: Cas9-Nickase

    Cas9-Nickase is a Cas9 without iGEM restrction-sites but full catalytic activity.

    • the HA and the mCherry are separated by a P2A sequence that results in 2 separate proteins, mCAT-1-HA and mCherry
  • p14rz_011: TetO13_CMVmin_SLC7A1_HA_mCherry

    • inducible vector encoding mCAT-1 fusion protein under control of a modified Tet promoter (Ptet) harboring a spacer between the 13mer tetO operator and the minimal promoter (TetO13–CMVmin)
