Porcine Pulmonary Artery Endothelial Cells are derived from healthly porcinine pulmonary vascular tissue. Porcine Pulmonary Artery Endothelial Cells are grown in T25 tissue culture flasks pre-coated with gelatin-based solution for 0.5 hour and incubated in AcceGen Biotech's Culture Complete Growth Medium generally for 3-7 days. Cultures are then expanded. Prior to shipping, cells are detached from flasks and immediately cryo-preserved in vials. Each vial contains at least 1x10^6 cells per ml and are delivered frozen.Porcine Pulmonary Artery Endothelial Cells can be used in assays of cell to cell adhesion, migration, vascular tube formation, or transendothelial resistance (TER). Standard biochemical procedures performed with endothelial cell cultures include RT-PCR, Western blotting, immunoprecipitation, immunofluorescent staining or immunofluorescent flow cytometry or generating cell derivatives for desired research applications.
