Abstract:
A method combining the techniques of immunoaffinity separation and continuous flow centrifugal separation is provided for selective separation of a nucleated heterogeneous cell population from a heterogeneous cell mixture. The heterogeneous cell mixture is intimately contacted to promote binding thereto by particles having attached a substance that actively binds to a specific desired type of cell out of the cell mixture. The particles are selected so that the sedimentation velocity of the particle/cell conjugate differs sufficiently from those of other cells in the cell mixture to allow its separation by means of a continuous flow cell separator. The method rapidly processes large volumes of cell mixture with the high accuracy expected of immunoaffinity separation and can be used to separate, for example, various types of leukocytes from whole blood, bone marrow concentrate, or a peripheral blood stem cell concentrate; or precursors of lymphokine activated killer cells, tumor infiltrating lymphocyte cells, or activated killer monocytes from lymphocyte or monocyte cell concentrates or from a tissue cell preparation.
Abstract:
A method, and useful apparatus for the preparation of pharmaceutical compositions comprising a complex of an antigen component and the corresponding antibody component in a pharmacologically acceptable carrier.
Abstract:
A system for the selective separation of a specific cel population from a heterogeneous cell mixture is disclosed herein. Means are provided for obtaining a selective cell concentrate from the heterogeneous cell mixture by separating the selective cell concentrate based upon the physical or biological properties of the concentrate. This may be done by centrifugation, if desired. A container is provided having particle means, the particle means being attached to a substance that is active for binding to a specific desired cell. One brings the cell concentrate into contact with the particle means within the container, for example, by providing sterile connection between the site where the cell concentrate is formed and the container. This permits incubation of the cell concentrate with the particle means, to thereby selectively bind a specific cell population from the cell concentrate to the particle means, creating a particle/cell conjugate. Magnetic means are then provided for separating the particle/cell conjugate from the remainder of the cell concentrate. A two-magnet system may be used to form the separation.
