1. OriCell Embryoid Body EB Formation Medium Cat No MUXES 90051 The formation of embryoid body EB is the principal step in the differentiation of ES cells When maintained in the EB formation medium and in the absence of MEF feeder layers ES cells differentiate spontaneously and then form three dimensional aggregates This structure facilitates multicellular interactions in which cell cell contact exists and gap juncitons may be established IMPI0070A3 MUBES 01201 Page 9 of 14 6 cyagen Protocol 1 10 11 12 Dissociate OriCell Strain C57BL 6 Mouse ESCs RFP by incubating the cells with trypsin solution at 379C for 1 2 min Add an appropriate volume of Cyagen OriCell EB Formation Medium e g 3 mL for each well of six well plate to stop reaction and gently pipette up and down until cells in colonies become single cells Transfer cell suspension into a 15 ml conical tube and centrifuge at 250 X g for 5 minutes to pellet the cells Carefully aspirate as much of the supernatant as possible Add appropriate amount of Cyagen OriCell EB Formation Medium to the conical tube and gently resuspend the cells Plate cell suspension in 100 mm adherent dishes Incubate the adherent dishes in a 379C incubator for 30 40 minutes to separate Mouse Embryonic Fibroblasts from OriCell Strain C57BL 6 Mouse ESCs RFP Carefully collect the suspending OriCell Strain C57BL 6 Mouse ESCs RFP and adjust the cell concentrat
