摘要:
Microwells, which are open on both sides and are arranged two-dimensionally in a microwell matrix (4), are hermetically closed by pressure on both sides using plugs (6) covered with a sealing sheet (11). A layer of elastic material (9), which is arranged between the plug (6) and the sealing sheet (11), guarantees uniform pressure on all the microwells of a microwell matrix (4) which is loosely held by a frame structure (1). Continuous peripheral elevations (2), which protrude in both directions at right angles to the plane of the microwell matrix (4), ensure that the deformable thin layer of elastic material (9) does not escape sideways between the plug (6) and the microwell matrix (4) during the pressing process. A plurality of microwell matrices (4) are held simultaneously by the frame structure (1) and are hermetically closed by a corresponding number of allocated plugs (6), which are fastened to a base plate (7) and a cover plate (8), respectively.

摘要:
The invention relates to a novel purified recombinant αVβ3 adhesion receptor which shows an unimpaired ligand binding activity, and a process for preparing said soluble non-membrane bound receptor in excellent yields by recombinant techniques using a baculovirus-insect cell expression system. The so-synthesized soluble receptor may be used very easily as screening tool for new therapeutic compounds which may inhibit the natural αVβ3 adhesion receptor. Such therapeutic compounds which can be discovered very easily, fast and without health risk by means of the soluble receptors according to the invention may be, for example, RGD peptides or non-peptidic compounds mimicking the natural ligand epitopes. The invention relates, furthermore, to a corresponding process for preparing recombinant full-length αVβ3 adhesion receptor in excellent yields, additionally using detergents to dissolve the membrane bound receptor from the surface of the host cell.
