Preparative separation of human T cells reactive with the OKT4 monoclonal antibody

Abstract

A cell separation technique is described which can provide large numbers (i.e. greater than 5 x 10(7)) of human lymphoid cells which are positively and negatively selected for their ability to react with the OKT4 monoclonal antibody. Peripheral blood lymphocytes are depleted of plastic-adherent cells and then exposed to OKT4 antibody. Unbound OKT4 antibody is removed by washing and then this OKT4-exposed cell population is placed on plastic Petri dishes that are coated with affinity-purified goat anti-mouse immunoglobulin. Cells which do not bind the OKT4 antibody (OKT4- cells) can be obtained by gently washing the nonadherent cells from the plates, while the adherent (OKT4+) cells can be recovered by vigorous pipetting. This procedure yields functional OKT4+ and OKT4- cell populations with a purity which approaches that obtained by separation using the fluorescence-activated cell sorter. The principal advantages of this plate separation technique are that: (1) large numbers of functional cell populations can be obtained; (2) very small quantities of monoclonal antibody (e.g. 1:10(4) dilution of ascites) are required; and (3) sterility of the cell preparations can be maintained quite easily.

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
