Abstract: Methods and devices for rapid lateral flow immunoassays to detect specific antibodies within a liquid sample while also validating the adequacy of the liquid sample for the presence of immunoglobulin and the integrity and immunoreactivity of the test reagents that detect the antibodies of interest, without requiring instrumentation. The methods and devices provide for delivery of a diluted liquid sample to a single location that simultaneously directs the liquid flow along two or more separate flow paths, one that serves as a positive control to confirm that all critical reagents of the test are immunoreactive, and that the sample being tested is adequate, and the other to detect specific antibodies if present.

Abstract: The present invention provides a device for processing, sampling, and diluting a fluid and for detecting an analyte within the processed, sampled, and diluted fluid. In the device for processing, sampling, and diluting a fluid, an amount of fluid to be processed, sampled, and diluted is accepted by a compressible porous membrane; a portion of the membrane saturated with the fluid is isolated thereby defining a predetermined sample volume of fluid; and the predetermined fluid volume sample is then released from the isolated membrane with a specified quantity of a fluid diluent to provide a diluted fluid sample. Analytes within the diluted fluid sample are detected by test strips in fluid contact with the diluted fluid sample.

Abstract: Highly immunoreactive regions of gp41 of HIV-1, gp32 of HIV-2 and p24 of HIV-1 were identified using synthetic peptides. Superior immunoassay performance is obtained with these peptides linked to carrier proteins as compared to use of the free peptides. Additional natural and unnatural variants of these reactive regions to define a set of peptides that, as cysteine-linked peptide-protein conjugates, provide optimal immunoassay performance including high immunoreactivity with HIV antibody positive samples, low reactivity with negative samples, high discrimination between positives and negatives, and high specificity. These peptide conjugates further permit simultaneous detection of HIV-1 and HIV-2 antibodies, and make possible rapid and simple test formats that require no instrumentation for detection of these antibodies.

Abstract: A vaccine affording protection against attachment of Neisseria gonorrhoeae (N.g.) to human cells, and consequent infection, is prepared from a fragment of pili protein isolated from gonococci. This fragment contains the shared antigens between pili from different N.g., in an exposed form.

Abstract: A vaccine affording protection against infection by Neisseria gonorrhoeae (N.g.) microorganisms is prepared from principal outer protein material isolated from gonococci.
