The Human Embryo PrimaCell™ 1: Normal Embryonic Chorion Cells is for rapid (7-10 days) isolation and growth of normal embryonic chorion cells from human embryo tissues. This system features an optimal condition of tissue dissociation system, Embryo OptiTDS™ that yields 5-7 times of single cells more than most of the tissue dissociation protocols published in the literature. In addition, this system ensures a high viability of the target cells with improved gradient contained in the culture medium. With CHI's proprietary fibroblast inhibitory system, FibrOut™, cells are growing with minimal amount of the unwanted cells such as fibroblasts.
