Experimental details: Western blot analysis was performed on membrane enriched extracts (30 µg lysate) of A-549 (Lane 1), MCF-7 (Lane 2), HeLa (Lane 3), HepG2 (Lane 4), Caco2 (Lane 5), A-431 (Lane 6), SH-SY5Y (Lane 7) and U-2 OS (Lane 8). The blot was probed with Anti-gamma Tubulin Mouse Monoclonal Antibody (Product # MA1-850, 1 µg/mL) and detected by chemiluminescence using Goat anti-Mouse IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A28177, 0.25 µg/mL, 1:4000 dilution). A 51 kDa band corresponding to gamma Tubulin was observed across the cell lines tested. Known quantity of protein samples were electrophoresed using Novex® NuPAGE® 10 % Bis-Tris gel (Product # NP0321BOX), XCell SureLock™ Electrophoresis System (Product # EI0002) and Novex® Sharp Pre-Stained Protein Standard (Product # LC5800). Resolved proteins were then transferred onto a nitrocellulose membrane with iBlot® 2 Dry Blotting System (Product # IB21001). The membrane was probed with the relevant primary and secondary Antibody following blocking with 5 % skimmed milk. Chemiluminescent detection was performed using Pierce™ ECL Western Blotting Substrate (Product # 32106).

Experimental details: Western blot analysis was performed by loading 50 µg of various whole cell lysates onto a 4-20% Tris-HCl polyacrylamide gel. Proteins were transferred to a PVDF membrane and blocked with 5% Milk/TBST for at least 1 hour. Membranes were probed with a mouse monoclonal antibody recognizing g-Tubulin (Product # MA1-850, Clone 4D11) at a dilution of 1:1000 overnight at 4°C on a rocking platform. Membranes were washed in TBS-0.1%Tween 20 and probed with a goat anti-mouse-HRP secondary antibody (Product # 31430) at a dilution of 1:20,000 for at least one hour. Membranes were washed and chemiluminescent detection performed using Pierce Super Signal West Dura (Product # 34075).

Experimental details: Knockdown of gamma Tubulin was achieved by transfecting HeLa cells with gamma Tubulin specific validated siRNA (Silencer® select Cat # s14502). Western blot analysis (Fig a) was performed using modified whole cell extract (1% SDS) from the gamma Tubulin knock down cells (lane 3), non-specific scrambled siRNA transfected cells (lane 2) and untransfected cells (lane 1). The blots were probed with Anti-gamma Tubulin mouse monoclonal antibody (Product # MA1-850, 1:1000) and Goat anti-Mouse IgG (H+L) Superclonal Secondary Antibody, HRP conjugate (Product # A28177, 1:5000 dilution). Densitometric analysis of this western blot is shown in histogram (Fig b). Loss of signal upon siRNA mediated knock down confirms that antibody is specific to gamma Tubulin.

Experimental details: Immunohistochemistry was performed on normal deparaffinized human Colon tissue. To expose target proteins, heat induced antigen retrieval was performed using 10mM sodium citrate (pH6.0) buffer, microwaved for 8-15 minutes. Following antigen retrieval tissues were blocked in 3% BSA-PBS for 30 minutes at room temperature. Tissues were then probed at a dilution of 1:200 with a mouse monoclonal antibody recognizing gamma Tubulin (Product # MA1-850) or without primary antibody (negative control) overnight at 4°C in a humidified chamber. Tissues were washed extensively with PBST and endogenous peroxidase activity was quenched with a peroxidase suppressor. Detection was performed using a biotin-conjugated secondary antibody and SA-HRP, followed by colorimetric detection using DAB. Tissues were counterstained with hematoxylin and prepped for mounting.

Experimental details: Figure 5 MYC overexpression induces double-strand breaks in DNA. A) A SV40-transformed human lung cell line, WI-38 VA13, stably-expressing c-MYC, L-MYC, or N-MYC, were lyzed and immunoblots were analyzed for phosphorylated histone H2AX (anti-gammaH2AX) and GADPH (anti-GADPH). As a positive control for DNA damage detection, parental cells were treated with etoposide and analyzed via immunoblotting. Cell lysates were also analyzed for overexpression of MYC variants. B) The same cells lines as in A were treated with the PRKDC inhibitor, KU0060648, for 8 h, lyzed and immunoblotted for phosphorylated histone H2AX (anti-gammaH2AX) and gamma-tubulin (anti-gamma-tubulin). Signal intensities of immunoblots were quantified using ImageJ.
