20 nM is correspond to 20 nM Bortezomib concentration (1x10 6 U-266 Cells / 2 ml / well + 20 nM Bortezomib in 2 ml), After incubation, the cells were taken to a falcon tube and centrifugated at 1000 rpm for 10 minutes. Then, the supernatant was gently removed and discarded, while the cell pellet was lysed by adding 50 µl of chilled Cell Lysis Buffer (1X) to get cell lysate. Then, the cell lysate was incubated on ice for 10 minutes before centrifugation at 10000g (~14000 rpm) for 1 minute. Next, the supernatants were transferred to new microcentrifuge tubes. So as to measure caspase-3 enzyme activity, reaction mixture was prepared in 96-well plates with the addition of 50 µl of Reaction Buffer (2X) (containing 10 mM DTT), 50 µl of sample and 5 µl of caspase-3 colorimetric substrate (DEVD-pNA) and incubated for 2 hours at 37°C in 5% CO2. After that, absorbance of the sample was read under 405 nm wavelengths by Elisa reader (Thermo Electron Corporation Multiskan Spectrum, Finland). 3.2.6.2. Bradford Protein Assay for Protein Determination Protein concentrations were measured by Bradford assay by using bovine serum albumin (BSA) as the standart. The Bradford protein assay is one of the spectroscopic analytical methods that are utilized to find out the total protein concentration of a sample (Bradford 1976). The method is also known as colorimetric assay because the addition of the sample causes color changes from brown that is cationic form to blue which is anionic form. Moreover the color of the sample becomes darker and the measured absorbance rises with the protein concentration increases. Basic principle of this method is absorption shift from 470 nm to 595 nm. When Coomassie Brilliant Blue G-250 (CBB G-250) dye binds to proteins through Van der Waals forces and hydrophobic interactions from its sulfonic groups, absorption occurs. In general, binding of dye to proteins becomes lysine, arginine and histidine residues, it also can bind tyrosine, tryptophan and phenylalanine weakly. Caspase-3 activity levels were normalized to protein concentrations determined by Bradford protein assay. A series of standard protein solutions were prepared via serial dilution using BSA (Bovine Serum Albumine) diluted with 1X PBS (Phosphate Buffered Saline) (Table 3.1). 53
The preparation of stock BSA Standard was given in Appendix B. Table 3.1.
