- Western blot analysis of STAT2 was performed by loading 20 µg of HeLa (lane1), HEK-293 (lane2), A431 (lane3) and A549 (lane4) 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). Proteins were transferred to a PVDF membrane and blocked with 5 % skim milk for 1 hour at room temperature. STAT2 was detected at ~90 kDa using STAT2 Recombinant Rabbit Polyclonal Antibody (Product # 710135) at 1 µg-3 µg/mL in 2.5 % skim milk at 4°C overnight on a rocking platform. Goat anti-Rabbit IgG-HRP Secondary Antibody (Product # G-21234) at 1:5000 dilution was used and chemiluminescent detection was performed using Pierce™ ECL Western blotting Substrate (Product # 32106).

- Immunofluorescent analysis of STAT2 was done on 70% confluent log phase HeLa cells. The cells were fixed with 4% paraformaldehyde for 15 minutes; permeabilized with 0.25% Triton X-100 for 10 minutes followed by blocking with 5% BSA for 1 hour at room temperature. The cells were incubated with STAT2 Recombinant Rabbit Polyclonal Antibody (Product # 710135) at 2 µg-4 µg in 1% BSA and incubated for 3 hours at room temperature and then labeled with Alexa Fluor® 488 Goat anti-Rabbit IgG Secondary Antibody (Product # A-11008) at a dilution of 1:400 for 30 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (Product # S36938). F-actin (Panel c: red) was stained with Alexa Fluor® 594 Phalloidin (Product # A12381). Panel d is a merged image showing translocated STAT2 in nucleus. Panel e shows cytoplasmic localization of STAT2. Panel f shows no primary antibody control. The images were captured at 20X magnification.

- Immunohistochemistry analysis of STAT2 showing staining in the cytoplasm of paraffin-embedded human cervical carcinoma (right) compared to a negative control without primary antibody (left). To expose target proteins, antigen retrieval was performed using 10mM sodium citrate (pH 6.0), microwaved for 8-15 min. Following antigen retrieval, tissues were blocked in 3% H2O2-methanol for 15 min at room temperature, washed with ddH2O and PBS, and then probed with a STAT2 Recombinant Rabbit Polyclonal Antibody (clone 1HCLC) (Product # 710135) diluted in 3% BSA-PBS at a dilution of 1:20 overnight at 4°C in a humidified chamber. Tissues were washed extensively in PBST and detection was performed using an HRP-conjugated secondary antibody followed by colorimetric detection using a DAB kit. Tissues were counterstained with hematoxylin and dehydrated with ethanol and xylene to prep for mounting.

- ChIP- qPCR analysis of STAT2 was performed with 3 µg/mL of the STAT2 Recombinant Rabbit Polyclonal Antibody (Product # 710135) on sheared chromatin from 2 million HeLa cells treated with IFN-alpha (50 ng/mL) for 1h using the MAGnify Chromatin Immunoprecipitation System (Product # 49-2024). Normal rabbit IgG (3 µg/mL) was used as a negative IP control. The purified DNA from each ChIP sample was analyzed by StepOnePlus Real-Time PCR System (Product # 4376600) with primers for the promoter of active GLS1 gene, used as positive control target, and the OAS1 gene, used as negative control target. Data is presented as fold enrichment of the antibody signal versus the negative control IgG using the comparative CT method.
