  • Publication number: 20040072176
    Abstract: Use of dipsticks to test for the presence of target nucleic acid in a sample solution is described. The dipsticks comprise a contact end for contacting the sample solution and a capture zone, remote from the contact end, to which a capture probe is immobilised. The capture probe is capable of hybridising to the target nucleic acid. The sample solution is contacted with the contact end of the dipstick and travels by capillary action to the capture zone. If target nucleic acid is present in the sample solution it is captured and can be detected at the capture zone. The capture probe is immobilised to the capture zone by a spacer. Use of the spacer increases the stability of the interaction between the capture probe and the target nucleic acid and thus improves the sensitivity of target nucleic acid detection. Detection probes with spacers are also described.

  • Patent number: 6716842
    Abstract: Compounds of formula I: wherein X, E, and R′ have any of the values defined in the specification, and their pharmaceutically acceptable salts, lower blood glucose levels and are useful for treating diseases in mammals such as Non-Insulin Dependent Diabetes Mellitus. Also disclosed are pharmaceutical compositions, processes for preparing compounds of formula (I) and intermediates useful for preparing compounds of formula I.

  • Publication number: 20040053256
    Abstract: Process for the production of methylenedianiline and its higher homologous products which comprises reacting aniline, or one of its derivatives, and formaldehyde, or one of its precursors, in one or two reactors in the presence of a solid acid catalyst selected from a zeolite or a silico-alumina, distilling the reaction water or the water added with the reagents.

  • Publication number: 20040053255
    Abstract: Dipsticks for testing for the presence of a target nucleic acid in a sample solution are described the dipsticks comprise a universal capture probe immobilised at a capture zone of the dipstick. The universal capture probe is capable of hybridising to a hook capture probe which is hybridised to the target nucleic acid in the sample solution. A contact end of the dipstick is contacted with the sample solution to cause hook capture probe hybridised to the target nucleic acid to move by capillary action to the capture zone where the target nucleic acid can be detected. Use of the universal and hook capture probes allows dipsticks to be prepared which can be used to capture any target nucleic acid, thereby simplifying preparation of the dipsticks. Specificity of target nucleic acid capture is then achieved by use of an appropriate hook capture probe. Methods and kits are also described.

  • Publication number: 20040048395
    Abstract: Dipstick tests for detecting analyte are described. In a preferred embodiment, a multiple biotinylated antibody capable of binding analyte is bound to an anti-biotin antibody labelled with colloidal gold and wicked up the dipstick with test solution thought to contain analyte. Complex formed between analyte, biotinylated anti-analyte antibody, and colloidal gold labelled anti-biotin antibody is captured at a capture zone of the dipstick. Presence of colloidal gold label at the capture zone indicates the presence of analyte in the test solution. The sensitivity of analyte detection using such methods is an order of magnitude higher than for comparable methods in which biotinylated anti-analyte antibody bound to analyte is wicked up the dipstick in a first step, and a colloidal gold labelled anti-biotin antibody is wicked up the dipstick in a separate step. Kits for performing the tests of the invention are also described.

  • Publication number: 20040014094
    Abstract: The invention provides a dipstick and a kit comprising the dipstick, for testing for the presence of a plurality of different targets in a sample solution which comprises: a dipstick having a plurality of different capture zones and, immobilised to each capture zone, a different capture moiety, each capture moiety capable of capturing a different target; and, separately, a plurality of different detection probes, each detection probe capable of binding to a different target and each detection probe being labelled with or enabling the formation of a detection signal so that the presence of each target is indicated by the formation of a signal at the capture zone for that target; wherein the target for at least two of the capture moieties is a disease causing micro-organism or a marker indicating the existence of a disease, disorder, or condition of the host from which the sample solution was derived, and wherein at least two of the capture moieties are capable of binding to different components or markers of t
