Abstract: Apparatus for transport of molecules including nucleic acid sequences in a bibulous carrier comprising a dry bibulous carrier defining a capillary transport path which supports the transport of the molecules when contacted with a solution containing the molecules.

Abstract: A method of assaying for the presence or quantity of a suspect nucleic acid in a suspect sample using a modified genetic probe in combination with an imaging procedure. The probe is modified by addition and provides an easy and very effective technique of modifying a genetic probe preparatory to its use in a kit. The genetic probe is then introduced into contact with DNA or RNA of the suspect sample and permitted to hybridize therewith. A kit for performing an assay using the modified probe is also disclosed.

Abstract: A solid phase immuno-assay system for assaying at least one analyte, in the form of a solid support having a plurality of receptors bound thereto. At least two of the receptors conjugate with the same analyte.A reaction container comprising a plurality of longitudinally arranged individual compartments, and a longitudinally extending single compartment.A card for assaying a plurality of samples for the same analyte, having a plurality of receptors for the analyte at different locations on the card.A method of performing an assay for the same analyte in more than one sample, by providing a receptor for the analyte at more than a single location on a solid substrate; exposing each of the receptors to different samples; and developing each of the receptor locations to indicate the presence of the analyte in each of the samples.

Abstract: A sheet for separating and retaining biological molecules. The sheet is activated with a compound for covalently binding a ligand to said sheet, and then coated with ligands having an affinity for the substance of interest. A method of using the sheet for isolating and separating substances of interest and methods for forming the sheet.
