Human Snail Antibody

Detection of Snail in A549 Human Cell Line by Flow Cytometry.

A549 human lung carcinoma cell line was stained with Goat Anti-Human Snail Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3639, filled histogram) or isotype control antibody (Catalog # AB-108-C, open histogram), followed by Fluorescein-conjugated Anti-Goat IgG Secondary Antibody (Catalog # F0109). To facilitate intracellular staining, cells were fixed and permeabilized with FlowX FoxP3 Fixation & Permeabilization Buffer Kit (Catalog # FC012).

Detection of Human Snail by Western Blot

SerpinA1 was regulated by SnailA. DLD-1 and SW480 cells were transfected with pcDNA-Snail (Snail), control vector pcDNA (vector), Snail siRNA (siSnail), or nontargeting siRNA (siNT), and Snail and serpinA1 protein levels were evaluated by western blot analysis. B. DLD-1 and SW480 cells were transfected with pcDNA-serpinA1 (serpinA1), control vector pcDNA (vector), serpinA1 siRNA (siSerpinA1), or nontargeting siRNA (siNT), and western blot analysis was performed for detection of Snail and SerpinA1 expression. C. DLD-1 and SW480 cells were transfected with pcDNA-Snail (Snail) or control vector pcDNA (vector), and ChIP assays were performed. The presence of the serpinA1 promoter (−516/−4) was verified in immunoprecipitates with either mouse IgG or anti-Snail antibodies, and assay inputs were analyzed using real-time PCR. The samples were loaded on agarose gels. D. Data show promoter enrichment in the anti-Snail immunoprecipitate relative to IgG.

Detection of Human Snail by Western Blot

Snail and serpinA1 promoted tumor progression through fibronectinA. DLD-1 and SW480 cells were transfected with pcDNA-Snail (Snail), control vector pcDNA (vector), Snail siRNA (siSnail), or nontargeting siRNA (siNT), and Snail, serpinA1, and fibronectin protein levels were evaluated by western blot analysis. B. DLD-1 and SW480 cells were transfected with pcDNA-serpinA1 (SerpinA1), control vector pcDNA (vector), serpinA1 siRNA (siSerpinA1), or nontargeting siRNA (siNT), and Snail, serpinA1, and fibronectin protein levels were evaluated by western blot analysis. C. DLD-1 and SW480 cells were transfected with pcDNA-fibronectin (Fibronectin), control vector pcDNA (vector), fibronectin siRNA (siFibronectin), or nontargeting siRNA (siNT), and Snail, serpinA1, and fibronectin protein levels were evaluated by western blot analysis. D., E. Invasion and migration assays were performed using transfected cells. Representative data are shown for cells that invaded (top) and migrated (bottom) in the presence of 1% FBS. *P < 0.05.
