Abstract: Methods are provided for determining the presence of an analyte present in a liquid sample involving: contacting the liquid sample with a predetermined amount of an analogue of the analyte and an excess of a first binding moiety, wherein the first binding moiety is capable of binding each of the analyte and the analogue independently; contacting the mixture with a second binding moiety; and determining the level of a signal indicative of the presence of the analogue-first binding moiety complex bound to the second binding moiety, wherein if the level of the signal determined is lower than the level of a maximum signal determined when no analyte is present, then analyte is present in the sample. Corresponding kits are also provided.

Abstract: An enzyme detection product for detecting the presence of an enzyme in a sample. The product includes: a reaction zone for receiving the sample; a visualization zone for presenting a signal in response to the detection of the activity of the enzyme; and a membrane. The membrane is interposable between the reaction zone and the visualization zone and prevents passage from the reaction zone to the visualization zone the components having a size greater than a threshold size. The reaction zone includes a reactant capable of reacting with the enzyme in order to generate a reaction product having a size less than a threshold size.

Abstract: There is provided an antibody granule, consisting essentially of one or more antibodies, or fragments derived thereof, granulated with an alkali metal salt. Also provided is a process for preparing said antibody granules. The granules can be used in an enzymatic stain bleaching or anti dye-transfer composition.

Abstract: An article for use in an enzymatic fabric cleaning process, said article containing one or more types of harmless micro-organisms capable of excreting enzymes useful in said fabric cleaning process. Furthermore, there is provided an enzymatic method of cleaning fabrics, whereby soiled fabrics are soaked with water in the presence of said article.

Abstract: A method of delivering a benefit agent to a selected area of a fabric for exerting a predetermined activity, wherein the area is pre-treated with a multi-specific binding molecule which has a high binding affinity to said area through one specificity and is capable of binding to said benefit agent through another specificity, followed by contacting said pre-treated area with said benefit agent, to enhance said pre-determined activity to said area. Preferably, the binding molecule is an antibody or fragment thereof, or a fusion protein comprising a cellulose binding domain and a domain having a high binding affinity to another ligand which is directed to said benefit agent. The method is useful for stain removal, perfume delivery, and treating collars and cuffs for wear.
