Toll-Like Receptor 4 Knockout (TLR4 KO) Mouse Lymphatic Endothelial Cells from�Creative Bioarrayare isolated from lymph node tissue of pathogen-free laboratory mice. Toll-Like Receptor 4 Knockout (TLR4 KO) Mouse Lymphatic 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 LYVE1 antibody, following the application of magnetic beads pre-coated with secondary antibody.
