- Western blot analysis of CREB was performed by loading 30 µg of K562 and Jurkat cell lysates using Novex®NuPAGE®4-12% Bis-Tris gel (Product # NP0321BOX), XCell SureLock Electrophoresis System (Product # EI0002), Novex® Sharp Pre-Stained Protein Standard (Product # LC5800), and iBlot® Dry Blotting System (Product # IB21001). Proteins were transferred to a nitrocellulose membrane and blocked with 5% skim milk for 1 hour at room temperature. CREB was detected at ~43 kDa using CREB Recombinant Rabbit Monoclonal Antibody (Product # 701120) at a 1:1000 dilution in 2.5% skim milk at 4°C overnight on a rocking platform. Detection was performed using an HRP-conjugated Goat anti-Rabbit secondary antibody (Product # G-21234) at a 1:5000 dilution and chemiluminescent detection was performed using Pierce™ ECL Western blotting Substrate (Product # 32106).

- Immunofluorescent analysis of CREB in serum-starved HeLa cells treated with insulin (100 ng/mL, 15 min) using a CREB recombinant rabbit monoclonal antibody (Product # 701120) followed by detection using an Alexa Fluor 488-conjugated goat anti-rabbit secondary antibody (green) (Image A). Nuclei were stained using DAPI (Image B) and actin stained with Alexa Fluor 594 phalloidin (red) (image C). Image D is a composite image showing nuclear localization of CREB.

- Flow cytometry analysis of CREB was performed on HeLa cells. Cells were fixed with 70% ethanol for 10 minutes, permeabilized with 0. 25% Tritonª X-100 for 20 minutes, and blocked with 5% BSA for 1 hour at room temperature. Cells were labeled with ABfinityª CREB recombinant rabbit monoclonal antibody (Product # 701120, red histogram) or with rabbit isotype control (pink histogram) at a dilution of 1:250 in 2.5% BSA. After incubation at room temperature for 3 hours, the cells were labeled with Alexa Fluor¨ 488 goat anti-Rabbit Secondary antibody (Product # A11008) at a dilution of 1:400 for 30 minutes at room temperature. The representative 10,000 cells were acquired and analyzed for each sample using an Attune¨ Acoustic Focusing Cytometer. The purple histogram represents unstained control cells and the green histogram represents no-primary-antibody control.

- Chromatin immunoprecipitation analysis of CREB was performed using cross-linked chromatin from 1 x 10^6 HCT116 human colon carcinoma cells treated with serum for 0, 15, and 60 minutes. Immunoprecipitation was performed using a multiplex microplate Matrix ChIP assay (see reference for Matrix ChIP protocol: http://www.ncbi.nlm.nih.gov/pubmed/22098709) with 1.0 µL/100 µL well volume of a CREB rabbit monoclonal antibody (Product # 701120). Chromatin aliquots from ~1 x 10^5 cells were used per ChIP pull-down. Quantitative PCR data were done in quadruplicate using 1 µL of eluted DNA in 2 µL SYBR real-time PCR reactions containing primers to amplify -15kb upstream of the human Egr-1 locus, or exon-1 or exon-2 of Egr-1. PCR calibration curves were generated for each primer pair from a dilution series of sheared total genomic DNA. Quantitation of immunoprecipitated chromatin is presented as signal relative to the total amount of input chromatin. Results represent the mean +/- SEM for three experiments. A schematic representation of the Egr-1 locus is shown above the data where boxes represent exons (black boxes = translated regions, white boxes = untranslated regions), the zigzag line represents an intron, and the straight line represents upstream sequence. Regions amplified by Egr-1 primers are represented by black bars. Data courtesy of the Innovators Program.
