WebThe in vitro proliferation assay can be used to determine whether or not cells are triggered to divide after exposure to a specific stimulus, or to assess differences between cell populations in their ability to divide in response to the same stimulus. Procedure 1) Cells in culture are given a specific stimulus. WebAt Charles River, an in vitro assay for assessing TTR binding was established, based on investigating competition of chemicals with T4 with binding to transport proteins using the TRβ-CALUX cell line. The TTR binding assay involves the incubation of a possible T4 competitor with a fixed amount of T4 and TTR.
