Abstract: Enzymes are immoblized, stabilized and evenly dispersed without destroying their activity by sequestering them within micropores of a solid carrier structure and filling the pores with a water-immiscible organic liquid, in which the enzyme remains active. The preferred solid carrier is a microporous membrane. The system is manufactued by providing a solid carrier having a microporous surface whose pores contain an aqueous solution, allowing an aqueous solution of enzyme to equilibrate with the solution in the pores, causing a controlled partial collapse of the pores to effectively trap the enzymes, and replacing the liquid in the pores with a water-immiscible organic liquid. The system can be used to assay for or produce an organic compound. It also can be used for slow release of an enzyme.

Abstract: 1. Strut for floor shutterings having a head piece serving as a support for the corners of four mutually abutting shuttering panels. 2.1 In a known strut of this type, it is necessary for the strut to be installed in a specific position, so that projections engage in recesses in the shuttering panels to form a lift-off catch. A strut of this type is therefore also not suitable for installation of the shuttering panels from above. The new strut, in contrast, permits installation in any of four possible positions of the head piece and also erection of the shuttering from above. 2.2 The base plate of the head piece is, in plan view, square in shape and has, on the head piece, projections and webs alternately offset by in each case 45 DEG , in each case in a square arrangement.   2.3 This strut simplifies installation and holds the shuttering panels, placed on it, together exactly, irrespective of whether the shuttering is erected from below or from above. A lift-off catch has proved superfluous. <IMAGE>

Abstract: This invention is directed toward providing a transatmospheric launch system that is essentially totally reusable, provides wide flexibility in choice of orbit, and may be launched quickly on short notice. The system of the invention is a two-stage horizontal takeoff and landing system. An orbiter vehicle (50) is integrated into the underside of an aircraft (2). Aircraft (2) has a cavity (4) opening aftwardly and downwardly to receive vehicle (50). Vehicle (50) and aircraft (2) are releasably connected by struts (30, 32). Aircraft (2) and vehicle (50) proceed to staging conditions under air breathing and then rocket power. Rocket engine (22) of aircraft (2) is throttled to produce a thrust differential with rocket engine (66) of vehicle (50). This differential causes vehicle (50) to automatically pivot away from aircraft (2) on struts (30, 32). After pivoting out of cavity (4), vehicle (50) is disengaged from struts (30, 32) and proceeds on its own to orbit. Aircraft (2) makes a conventional landing. Following reentry, vehicle (50) makes an unpowered horizontal landing. Separation is accomplished at a Mach number of about 3.3. In a second embodiment, the main engine of the orbiter (50′) is a scramjet (101) instead of a rocket.

Abstract: Purified enzymatic compositions are provided having alpha-amidating enzymes capable of catalyzing the conversion of a peptidyl compound having a C-terminal glycine residue to a corresponding peptidyl amide having an amino group in place of the C-terminal glycine. The purified compositions have specific activities above 25mU per mg protein and are sufficiently free of proteases to allow effective catalysis of even peptidyl compounds having L-amino acids. Biologically important alpha-amidated products such as calcitonin and other regulatory hormones are efficiently produced using the alpha-amidation reaction catalyzed by the enzymes. Purification by size exclusion chromatography in combination with strong anion exchange chromatography results in homogeneous enzyme species which are used to prepare antibodies specific for the alpha-amidating enzyme. A gene capable of expressing the alpha-amidating enzyme is ligated into an expression vector and transformed into a host cell capable of expressing the gene.
