- Paraphrase the text below: Series of test tubes were filled with the desired volume of the BSA (0.1, 0.2, 0.3… 1 ml) .PBS was added to this to make the volume of 1 mL. 5 mL of copper reagent was added to all the tubes. After proper mixing, all the tubes were incubated at room temperature for 15 minutes. 1 mL Folin reagent was added to each and mixed properly with the help of vortex mixer and incubated for 20 minutes. The intensity of the colour was then determined spectrophotometrically at 680 nm. The graph was than plotted between optical density and the amount of BSA. Proteins estimation was done for the detection for the amount of proteins present in the sample solutions by the Lowry methodHow much of 10,000x SYBR safe would you add to 50 ml to make a final concentration of 1x?
