Abstract: A lateral flow immunoassay for the detection of anti-drug antibodies against a biological drug includes a membrane having a capture area, a sample application area, a flow path from the sample application area to the capture area, and a conjugate area located in the flow path. The conjugate area has said biological drug detectably labeled and the capture area has said biological drug immobilized thereto.

Abstract: Methods for identifying strains of bacteria, particularly methods for serotyping Streptococcus pneumoniae in a sample, methods for detecting and/or classifying S. pneumoniae infection by serotype, array devices and kits for use in such methods are disclosed. Array devices comprise a set of capture antibodies immobilised on a substrate at pre-determined array positions, wherein the set of capture antibodies comprises serotype-distinguishing antibodies which differ in their binding specificity for different S. pneumoniae serotypes. Serotyping methods may employ whole cell detection utilising one or more detectable labels, including in situ labelling of array-bound cells.
