Competence-Specific RNA Polymerase in Streptococcus. SPNEU : The Binax NOW Streptococcus pneumoniae test is an immunochromatographic membrane assay used to detect pneumococcal soluble antigen in human urine and cerebrospinal fluid. Rabbit anti-S pneumoniae and antispecies antibodies are conjugated to visualizing particles that are dried onto an inert fibrous support. The resulting conjugate pad, Natural competence in Streptococcus pneumoniae is regulated by a quorum-sensing system which acts through accumulation and sensing of a peptide pheromone (CSP) to control many competence-specific genes acting in DNA uptake, processing, and integration. The period of competence induced by CSP lasts only 20-30 minutes..

A highly sensitive immunochromatography test kit, ODK0501, was developed using specific polyclonal antibodies against the C-polysaccharide moiety of Streptococcus pneumoniae for the rapid detection of S. pneumoniae antigen in sputum samples.
