Human Retinal Microvascular Endothelial Cells from Creative Bioarray are isolated from human retinal tissue. Human Retinal Microvascular Endothelial Cells are grown in T25 tissue culture flasks pre-coated with gelatin-based 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 at passage 3 are detached from flasks and immediately cryopreserved in vails.
