Science fair project... Help T.T
"A protein, albumin, was placed into four test tubes for each of the seven pH levels being used. Then the buffer solution for each pH level was placed into their respective tubes. After a period of ten minutes, Ninhydrin Isopropanol was placed into one of the tubes for each pH. This was repeated every ten minutes. After being centrifuged, the solutions were observed for color change and the absorbance was recorded using a spectrophotometer at 580nm. "
These are the materials needed for this science project and the procedure, but I am very confused... Actually, I get the point of this project and really want to do it, but I have no clue on how to.
when they say protien and albumin, am i suppsoed to add real food? and the buffer solution.. what shouldi use that as?? ninhydrin isopropanol. is that a liquid?
could you lay out the materials and the procedure in a way i could understand it a bit easily? :idea: :?:
