Latest Patents

One of his latest patents is titled "Mixing and separating solid phase supports by pressure variation." This invention utilizes gas-containing granules made of a resiliently compressible material, which have a density that varies with pressure. These granules serve as solid phase supports in liquid phase reactions, particularly in immunological reactions. By varying the pressure, the density of the granules changes, allowing for effective mixing and separation within the solution. In this process, granules with attached antibodies are combined with a solution containing an antigen. The application of varying pressure facilitates the mixing of the granules, enabling the antigen to bind to the antibody. Subsequently, the pressure is adjusted to move the granules to either the top or bottom of the solution, allowing for the separation of the solution from the granules.

Another significant patent by Place is for an "Apparatus for casting thin layer gel media in a mould and subsequently." This invention involves a mould designed for casting thin, cross-linked, polymerized resin films. When filled with the liquid to be polymerized, the mould is subjected to a centrifugal force field that exceeds the earth's gravitational field. This process helps to equalize the intimate structure of the polymer and expel any gas bubbles present. After curing the gel, a mixture of compounds intended for separation is introduced into the gel, which is then subjected to electrophoresis within the mould itself.
