- Western blot was performed using Anti-p300 Monoclonal Antibody (NM-11) (Product # 33-7600) and a 300kDa band corresponding to p300 was observed across cell lines tested. Whole cell extracts (1%SDS) (40 µg lysate) of HeLa (Lane 1), K-562 (Lane 2), NCI-H1299 (Lane 3) as seen in Fig (a), HUVEC (Lane 1), HUVEC treated with Glucose (25mM for 24hrs) (Lane 2) and HUVEC treated with Glucose (25mM for 24hrs) and then treated with LY294002 (25uM for 30min) (Lane 3) as seen in Fig (b) were electrophoresed using NuPAGE™ 3-8% Tris-Acetate Protein Gel (Product # EA0378BOX). Resolved proteins were then transferred onto a nitrocellulose membrane (Product # IB23002) by iBlot® 2 Dry Blotting System (Product # IB21001). The blot was probed with the primary antibody (1:1000 dilution) and detected by chemiluminescence with Goat anti-Mouse IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A28177,1:20000 dilution) using the iBright™ FL1500 Imaging System (Product # A44115). Increase in signal was observed after stimulating HUVEC cells with Glucose and its expression was inhibited by using LY294002- an inhibitor, decrease in signal was observed upon treatment. Chemiluminescent detection was performed using SuperSignal™ West Pico PLUS Chemiluminescent Substrate (Product # 34580). (Ref :https://doi.org/10.2337/db06-0519).

- Immunofluorescence analysis of p300 Monoclonal Antibody (NM-11) was performed using 70% confluent log phase HCT 116 cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 15 minutes, and blocked with 2% BSA for 45 minutes at room temperature. The cells were labeled with p300 Monoclonal Antibody (NM-11) (Product # 33-7600) at 1:100 dilution in 0.1% BSA, incubated at 4 degree celsius overnight and then labeled with Donkey anti-Mouse IgG (H+L) Highly Cross-Adsorbed Secondary Antibody, Alexa Fluor Plus 488 (Product # A32766), (1:2000 dilution), for 45 minutes at room temperature (Panel a: Green). Nuclei (Panel b:Blue) were stained with ProLong™ Diamond Antifade Mountant with DAPI (Product # P36962). F-actin (Panel c: Red) was stained with Rhodamine Phalloidin (Product # R415, 1:300 dilution). Panel d represents the merged image showing nuclear as well as cytoplasmic localization. Panel e represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.

- Knockdown of p300 Monoclonal Antibody (NM-11) was achieved by transfecting HCT 116 cells with p300 specific siRNA (Silencer® select Product # S4696, S4697). Immunofluorescence analysis was performed on untransfected HCT 116 cells (panel a,d), transfected with non-specific scrambled siRNA (panels e,h) and transfected with p300 specific siRNA (panel i,l). Cells were fixed, permeabilized, and labelled with p300 Monoclonal Antibody (NM-11) (Product # 33-7600, 1:100 dilution) followed by Donkey anti-Mouse IgG (H+L) Highly Cross-Adsorbed Secondary Antibody, Alexa Fluor Plus 488 (Product # A32766), (1:2000 dilution). Nuclei (blue) were stained using ProLong™ Diamond Antifade Mountant with DAPI (Product # P36962), and Rhodamine Phalloidin (Product # R415, 1:300 dilution) was used for cytoskeletal F-actin (Red) staining. reduction in signal of specific signal was observed upon siRNA mediated knockdown (panel i,l) confirming specificity of the antibody to p300 (Green). The Images were captured at 60X magnification.
