Abstract
An assembly for in vitro culture of cells of the present invention includes a culture vessel with at least one well. The well has an open top, a bottom and a wall with an inside surface. The assembly also includes at least one insert sized for placement within the well. The insert has an outside surface, an open end and a closed end. There is a microporous membrane at the closed end of the insert that closes the end and thereby forms a receptacle within the inset. The assembly further includes provisions for adjustably positioning the insert within the well between a first position where the closed end of the insert is a first distance from said bottom of the well and a second position where the closed end of the insert is a second distance from the well bottom.
Claims1
An assembly for in vitro culture of cells comprising:
- a culture vessel having at least one well therein, said well having an open top, a bottom and a wall having an inside surface;
- at least one insert sized for placement within said well, said insert having an outside surface, an open end, a closed end, said closed end being closed by a microporous membrane forming a receptacle within said insert;
- positioning means for adjustably positioning said insert within said well so that a distance between said closed end of said insert and said bottom of said well is selectively variable, wherein said positioning means comprises at least one outward projection on said outside surface of said insert and a plurality of steps projecting inwardly from said inside surface of said well at increasing distances from said bottom of said well, said projection and said steps disposed in a cam/cam follower relation for adjustably positioning said insert in said well by placing said projection on said steps.
