Abstract:
An improved Western blot method wherein the captured antibody of a test sample is detected by a probe specific for the captured antibody. The capture reagent can be a lysate, a recombinant protein or a synthetic peptide specific for the antibody to be detected. A test kit for performing the method also is provided.
Abstract:
A gastrostomy tube (30) combines a conventional dome (34) and tubular shaft (31) with one-way cross-slit duckbill valve (44). The one-way cross-slit valve is made of an elastomeric material and has a hollow cylindrical body with first and second ends and an axis and a passageway through the body, the passageway being entirely intercepted by a ridge and valley wall or web structure integrally joined to the cylindrical body.
Abstract:
Compounds of structure (I), wherein W is selected from (a), and (b), where Q is oxygen or sulfur, R and R are hydrogen or alkyl, or R and R , together with the nitrogen atoms to which they are attached, define a radical of formula (II) or (III), R is selected from hydrogen, alkyl, haloalkyl, optionally substituted phenyl, hydroxyalkyl, aminoalkyl, carboxyalkyl, (alkoxycarbonyl)alkyl, and (alkylaminocarbonyl)alkyl; Z is -CH2-, oxygen, sulfur, or -NR where R is hydrogen or alkyl, L and L are selected from a valence bond, alkylene, propenylene, and propynylene, R , R , R , and R are independently selected from alkyl, haloalkyl, halogen, cyano, amino, alkoxycarbonyl, and dialkylaminocarbonyl, Y is selected from oxygen, -NR , where R is hydrogen or alkyl, and (c), where n = 0, 1, or 2, and R is alkyl, inhibit the biosynthesis of leukotrienes. These compounds are useful in the treatment or amelioration of allergic and inflammatory disease states.
Abstract:
Disclosed is a stabilized, aqueous composition containing FK506. FK506 degrades rapidly in most aqueous matrices. The rate of degradation is decreased in the presence of blood cells or fragments of blood cells from human or animal sources. A number of matrices using blood components are possible. Blood can be used directly or the blood cells can be lysed. The blood is diluted with a solution of an alkali halide.
Abstract:
The present invention involves methods of improving the Ligase Chain Reaction (LCR ) amplification schemes by modifying at least one probe end so that the probability of the probe contributing to spurious ligation and signal development is greatly reduced. Only after specific hybridization of the modified probe with true target are the modified ends "corrected" by endonuclease IV in a target dependent fashion to allow participation of the probe in the enzymatic ligation reaction. Specific modifications include 3' phosphate blocking groups and nucleic acid overhangs containing an abasic site at the point of ligation. Further embodiments include probes modified to contain ribonucleotide moieties which, after amplification, can be cleaved by RNase to destroy the amplification products and reduce the risk of contamination.

Abstract:
Immunomodulatory macrocyclic compounds having formula (I), and pharmaceutically acceptable salts, esters, amides and prodrugs thereof, wherein one of R , R , R and R is a radical having formula (II), (III) or (IV), as well as pharmaceutically compositions containing such compounds and methods of immunomodulatory therapy utilizing the same.
Abstract:
This invention relates to genetically engineered enzymes, their ligand conjugates, their manufacture, and their use in qualitative or quantitative assays. A hybrid enzyme, such as an AP-epitope, has a foreign amino acid moiety (an epitope) inserted near the active site of the starting AP enzyme. The foreign amino acid moiety binds with an analyte, and, as a consequence of this binding, the enzymatic activity of the hybrid enzyme, AP-epitope, is modified. The changes in the enzymatic activity are dependent upon the presence, or the amount, of the analyte. In another embodiment, the hybrid enzyme consists of a cysteine introduced near the active site of an AP to give a hybrid enzyme. The cysteine on the hybrid enzyme serves as a point of conjugation of a ligand, such as theophylline, ferritin, thyroxine, or digoxigenin, to form the hybrid enzyme-ligand conjugate. The ligand binds with an antibody, an analyte or a binding molecule to an analyte and as a result of this binding, the enzymatic activity of the hybrid enzyme-ligand conjugate is modified or modulated.
Abstract:
The instant invention is a method of coupling compounds comprising the septs of: a) forming a maleimide derivative by reacting a maleimide containing compound having formula (I) with an amine functional compound capable of displacing the N-hydroxysuccinimide group; and b) reacting the derived maleimide of step (a) with a second amine functional compound.
