Patent number: 7211403Abstract: Device for assaying an analyte, comprising a labelling zone, where a label can bind to the analyte, in communication with a capture zone, wherein the pore size of the capture zone is such that label which is not bound to the analyte can migrate therethrough, whereas label which is bound to the analyte cannot. During migration from the labelling zone (large pore size) to the capture zone (small pore size), unbound label can pass into and through the capture zone, whereas bound label will be captured at the junction of the labelling zone and the capture zone. The device relies upon the label being smaller than the analyte, such that free label is not retarded by the capture zone. It is particularly suitable for assying analytes such as spermatozoa, which are large in comparison with a label such as a labelled antibody.Type: GrantFiled: May 13, 2002Date of Patent: May 1, 2007Assignee: Genosis LimitedInventors: Martin Barradine, Tracey Gurmin

Patent number: 6391654Abstract: A kit for testing male fertility comprises a vessel, a base unit, a liquid supply containing liquid and two filters. The first filter is a sample separation filter which forms a hindrance to transmission of spermatozoa. The second filter of the kit is a spermatozoa detection filter comprising a reagent for identifying spermatozoa. Activation of the kit is prevented until a transport medium, such as the liquid, fills a gap allowing spermatozoa to transmit to a detection zone. The kit may be of one-piece construction and utilizes a thin piece of filter material to separate motile from non-motile spermatozoa.Type: GrantFiled: September 8, 2000Date of Patent: May 21, 2002Assignee: Genosis LimitedInventor: Paul North Bateman
