1μl of the cell lysate was mixed with 200 μl of 5X Bradford reagent and 800 μl of water. O.D was measured at 595 nm. Standard curve of BSA was plotted using various dilutions of BSA protein by Bradford method. Protein estimation of the cell lysate samples was performed using the standard curve equation y=0.0695x + 0.0329 μg/μl
