- Western blot analysis of STAT3 in whole cell extract (80 µg) from HeLa cells treated with IFN1a (150 ng/mL, 15 min) using a STAT3 Recombinant Rabbit Polyclonal Antibody (Product # 710077) at a dilution of 5 µg/mL. Detection was performed using an HRP-conjugated Goat anti-Rabbit secondary antibody at a dilution of 1:5000 followed by chemiluminescence (ECL). Results show a band at ~84 kDa.

- Immunofluorescence analysis of STAT3 was done on 70% confluent log phase MCF-7 cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with STAT3 Antibody (3HCLC), Recombinant Rabbit Polyclonal Antibody (Product # 710077) at 1 µg/mL in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034) at a dilution of 1:2000 for 45 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® 555 Rhodamine Phalloidin (Product # R415, 1:300). Panel d is a merged image showing Nuclear and Cytoplasmic localization. Panel e is a no primary antibody control. The images were captured at 60X magnification.

- Immunohistochemistry analysis of STAT3 showing staining in the cytoplasm of paraffin-embedded human lung squamous 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 STAT3 Recombinant Rabbit Polyclonal Antibody (clone 3HCLC) (Product # 710077) 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.

- Enrichment of endogenous STAT3 protein at specific gene loci using Anti-STAT3 Recombinant Rabbit Polyclonal Antibody: Chromatin Immunoprecipitation (ChIP) was performed using Anti-STAT3 Recombinant Rabbit Polyclonal Antibody (Product # 710077, 5 µg) on sheared chromatin from 2 million HeLa cells treated with 100 ng/mL of IFN alpha for 30 minutes using the "MAGnify ChIP system" kit (Product # 49-2024). Normal Rabbit IgG was used as a negative IP control. The purified DNA was analyzed by 7500 Fast qPCR system (Product # 4351106) with optimized PCR primer pairs for the promoter of active GLS1, OAS1, cFOS gene, used as positive control target, and the SAT2, 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.
