    I'm very pleased with this video; You even went so far as to explain why the Lowry method is more sensitive (at around 19:10)

    I was browsing around to learn why carbonate buffer extracted proteins cannot be assayed using the more common BCA method. The composition of the BCA reagent presented here seems to give me the answer. Many thanks for this presentation!!

    hi again :) thanks for your answers, some things on the lowry are still not clear to me, the internet couldnt help, maybe you can: biuret: copper2+ and peptide becomes a complex. we talk about copper II (same as 2+). so this copper can offer 2 places for electrons to the Ns of the peptide. Thats how the complex is built. in the complex copper is still 2+. how does it come, it changes to copper 1+ ? who or what is reducing the copper? and when it became copper 1+, how can it still be in the complex? because in the complex it should always be copper 2+, not copper 1+. thank you very much for your time and your help!

    In the Lorry assay: the BSA concentracion to make de calibration curve can be 10mg/ml or we need a lower concentration?

    18.54 shouldn't the absorbance be at 500nm where the blue colour is in the visible spectrum? instead of 750nm

    • @logan2811
      @logan2811 5 лет назад +1

      Our eyes see reflected light off objects, if it absorbed blue we would not see it as blue. The color it absorbs makes the solution seem blue.

    i'm working with BCA assay , when i calculate the concentration of protein unknow from the formula of curve , i must multiplie with the dilution factor , how much is the dilution factor in this case and how you have calculated ?? thans to your answer

  • @achmadhanifmardinsyah5825
    @achmadhanifmardinsyah5825 3 года назад

    in lovvry assay.... in frist step you add C(2+), so if there no protein there still molibdenum blue formed right ? because C(2+) unreacted vvith peptide bond can reduce folin reagent

    Is fibers proteins which are insoluble in water give this test.
    Why dipeptides do not give this test. Is it essential to have peptide nitrogens only, terminal amino groups do not form this test.
