    James Wright is a good teacher. It was almost I was there with him. I can picture the entire process. He also gave details and principles behind why certain reagents are used. Awesome video. Would like it 100 times if I could.

    Great video! and for everyone alarmed by him not wearing gloves, it's very normal in bacteriology research!

    I appreciate the buffer compositions that you overlayed on the video.

    Took me 8 weeks to successfully express a protein, it's pretty simple in theory but doesn't always work smoothly in the lab, great video though!

    Does anyone have any good sources for how this is done at the large industrial scale?

    i clapped when i see a beautiful nice band u got after purification. nice video

    That plasmid is missing a marker needed for individual colonies separation by color: a screening marker, that is in the MCS region.

    • @nels6991
      @nels6991 5 лет назад +2

      the screen is already done by inserting the antibiotic resistance gene. A color marker would only be needed if the plasmids were a mix of plasmids with the target sequence and plasmids without the target sequence.

    Hi, can we store the supernatant obtained after sonication and centrifugation that has expressed proteins?

    Do you also use any eukaryotic system for protein expression followed by purification than bacterial system?

  • @nels6991
    @nels6991 5 лет назад

    Are these E. coli producing proteins by cytosolic production, Inclusion body formation, secretory production, or excretory production?

    if the protein isn't expressed, what does that indicate? what mistakes could I have made?

    • @Structuralbiology
      @Structuralbiology 3 года назад

      Inducer is not able to remove repressor or other reasons may be that your bacterial does not allow the expression of protein

    1) The optical density of the E.Coli culture during IPTG induction and IPTG concentration? 2)Too much Ni-beads for that volume of the supernatant, so probably there was nonspecific binding of other protein to the beads leads to the tiny bands in elution lane. 3)The safety issue while the use of glass beaker for sonication. 4) no sample loading for wash step as well as beads!!

      If you're working with microorganisms near to a flame. Its dangerous wear gloves. Also the flame sterilize very good the surroundings and usually the bacteria had a antibiotic resistence to keep it clean.
