Rabbit Cardiac Microvascular Endothelial Cells from Creative Bioarray are isolated from heart tissue of New Zealand White Rabbit. Rabbit Cardiac Microvascular Endothelial Cells are grown in T25 tissue culture flasks pre-coated with gelatin-based coating solution for 2 min and incubated in Creative Bioarray’ 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. The method we use to isolate endothelial cells was developed based on a combination of established and our proprietary methods. These cells are pre-coated with PECAM-1 antibody, following the application of magnetic pre-coated with secondary antibody.
