In Topic: FRET based inhibition assay

Yes I'm using black plate (the bottom is black as well) and I paid attention to bubbles as well.
So for the gain, my method is not correct?
You are saying that is better to assume the positive control (protease+substrate without inhibitor) as the well will produce the highest fluorescence instead of to insert a number, right?
The filters are long pass.

Thanks I will have a look to the videos!

Hi,
I would like to know if there is something wrong in my protocol and how I can improve my measurements in term of signal noise and reproducibility. I was wondering if it's better to use the bottom optic instead of the top one and if the method I used to adjust the gain is correct. Can you suggest me any tips to improve my measurements?
Thanks :)

But I should use the peptidic fragment the enzyme generate to make the calibration curve, or can I use only the fluorophore (in this case the anthranilic acid)?

Maybe is due to the percentage of glycerol?

I'm a little bit confused now..I was thinking the same of PhDinAcronyms
