<Experimental Background>
1. RIPA buffer
Radio-immunoprecipitation assay (RIPA) buffer causes cell wall to break leading to efficient cell lysis and protein solubilization from cultured animal cells. It also avoids interfering with immunoreactivity of proteins, degradation of protein and biological activity. In addition, RIPA buffer is appropriate for immunoprecipitation and western blot assays because it minimizes binding of non-specific protein which results in low background in such assays.

<Results & Discussion>
In conclusion, the main objective of the experiment was to determine the appropriate protein concentration based on Bradford assay. This is to ultimately prepare 75μg/50μL (or 1.5μg/μL) of western blot sample prior to perform western blot assay. In this investigation, due to possible errors and limitations, the results of OD600nm measurement & protein concentration might not be very accurate.
