Abstract:
Liquid formulations, suitable for use in extending the vase-life of cut flowers and which resist the development of unsightly discoloration and turbidity comprise from about 55 parts by weight to about 98 parts by weight of a sugar; from about 0.05 part by weight to about 1 part by weight of an inhibitor of aminocyclopropanecarboxylate synthase selected from L-trans-2-amino-4-(2-aminoethoxy)-3-butenoic acid and carboxymethoxylamine; from about 0.1 part by weight to about 5 parts by weight of an antimicrobial agent; from about 1 part by weight to about 5 parts by weight of aluminum sulfate; and from about 0.1 part by weight to about 5 parts by weight of a dicarboxylic acid of from two to six carbon atoms. All parts by weight based upon the total weight of the dissolved solid components.
Abstract:
An assay to simultaneously detect the presence of one or more HIV subtypes of HIV-1 antibody and/or HIV-2 antibody in a test sample is disclosed. The analytes are captured on either the same or different solid phases, and the presence of the analytes is determined by detecting a signal generated by using a cocktail of synthetic and recombinant antigen-containing indicator reagents. Preferred indicator reagents include a synthetic19 amino acid cyclic peptide homologous to an immunodominant region of HIV-1 gp 41 and a synthetic19 amino acid cyclic peptide homologous to an immunodominant region of HIV-2 gp 36.

Abstract:
Pharmaceutical compositions for aerosol delivery comprising (a) a medicament, (b) a non-chlorofluorocarbon propellant, and (c) tocopherol or a pharmaceutically acceptable derivative thereof, as well as a method for preparing such compositions in which unwanted aggregation of the medicament is prevented without the use of surfactants or cosolvents.
Abstract:
Embodiments of the invention provide methods of preparing an activated acridinium microparticle. Generally, the methods involve direct covalent coupling or an affinity format. The direct covalent coupling method involves coating a microparticle with a proteinaceous compound. Then, a 10-methyl-N-tosyl-N-(2-carboxyethyl)-9-acridinium carboximide trifluoromethane sulfonate is coupled to the proteinaceous compound. In the affinity format, a microparticle is coated with a biotinylated proteinaceous compound. The microparticle is reacted with an anti-biotin labelled 10-methyl-N-tosyl-N-(2-carboxyethyl)-9-acridinium carboximide trifluoromethane sulfonate. Methods are also provided for using such a microparticle. Those methods of use can estimate transfer efficiency, calibrate optics, and measure membrane pore size of a chemiluminescence based instrument. Test elements for analytical instruments are also provided.
Abstract:
The method and apparatus for thermal cycling of nucleic acid assys includes a blended fluid stream produced from a plurality of constant velocity, constant volume, constant temperature fluid streams wherein to provide a variable temperature, constant velocity, constant volume fluid stream which is introduced into a sample chamber for heating and cooling samples contained therein. By diverting and altering the ratio of the constant temperature fluid streams relative to one another, the blended fluid stream is rapidly variable in temperature, providing for almost instantaneous temperature change within the environment defined by the sample chamber.
Abstract:
A particle count probe comprises a wafer having an aperture. A first member is provided having a fluid passageway. A second member is removably mounted to the first member, and cooperates with the first member and the wafer to position the wafer so that the aperture of the wafer aligns with the fluid passageway.
Abstract:
Novel macrolide compounds (semisynthetic analogs of asomycin and FK-506) of formula (II) and phamaceutically acceptable salts, esters, amides and prodrugs thereof, wherein X is a substituent selected from among radicals having the subformulae (IIa), (IIe), (IIj) and (IIk) and other heretocyclic radicals, as well as pharmaceutical compositions and methods of immunomodulatory treatment utilizing same.
Abstract:
The closure has a locking ring (107) connected to a collar (108), having an internal planar face (109), at a frangible annular portion (110), which can be ruptured to gain immediate access to the contents of a container. A stopper member (120) is fixed to the collar (108) for selectively connecting the closure (100) to an anaesthetic transfer device. A discharge passage (123) and a venting passage (124) extend through the stopper member (120) for communication with a container (103) engaged by the collar (108). A first pierceable diaphragm (125) is located within and occludes the discharge passage (123), and second pierceable diaphragm (129) is located within and occludes the venting passage (124). Upon rupturing the frangible annular portion (110), the internal face (109) prevents the closure (100) from being fitted on another container.
Abstract:
