The in vitro cultivation of amniotic fluid cells and Procedure
chorionic villi is an essential part of every KREAvital Prenatal Medium may be used for: diagnostic cytogenetics laboratory, since the preparation of metaphase chromosome spreads is -Primary culture of amniotic fluid cells dependent upon obtaining cells in division. -Culture of passaged amniotic fluid cells KREAvital Prenatal Medium PLUS is specifically optimized for the primary culture of human amniotic fluid cells and chorionic villi samples used in prenatal diagnostic testing. The medium is a specialized version of KREAvital Prenatal Medium (Complete),as it has enhanced buffering The following protocol and the volumes
