Product Name	Mycoplasma pneumoniae IgM - ELISA
# of Samples	1 x 96 Assays.
Intended Use	The Mycoplasma pneumoniae IgM - ELISA is intended for the qualitative determination of IgM class antibodies against M. pneumoniae in human serum or plasma (citrate).
Introduction	The mycoplasms belong to the class Mollicutes comprising three distinct families and four genera, one of which is Mycoplasma with over 60 species. Mycoplasmae are the smallest freeliving organisms known (300 to 500 nm in diameter) and unlike regular bacteria they lack a cell wall. Mycoplasms are extracellular parasites, especially on mucous membranes, which can cause infections in hu-mans, animals, plants, and cell cultures. Mycoplasma pneumoniae is primarily a respiratory pathogen (obligat) in humans involving the nasopharynx, throat, trachea, bronchi, bronchioles, and alveoli. Other Mycoplasmae, M. buccale, M. faucium, M. orale and M. salivarium are commensals in the oral cavity. Mycoplasma hominis and Ureaplasma urealyticum inhabit primarily the genital tract and may act as opportunistic invaders. M. pneumoniae is by far the most important pathogen of this group. Infection with M. pneumoniae occurs worldwide, its epidemiology has been studied primarily in the USA, Europe, and Japan. Infections are endemic in larger urban areas, and epidemic increases are observed at varying intervalls. Mycoplasma pneumoniae has been estimated to cause 15-20% of all pneumoniae; the rate is highest in children and young adults. 74% of infections with M. pneumoniae are asymptomatic, reinfection may occur. Naturally acquired immunity to infection with M. pneumoniae appears to be of limited duration (2-3 years). Infection may be identified by Microscopy Hemadsorption, Tetrazolium reduction (specific for M. pneumoniae), Complement fixation Detection of antibody production by ELISASerology: complement fixation (CF), neutralization (N) and hemagglutination-inhibition (HAI); Detection of antibodies and the hexon antigen by ELISA.
Principles of the assay	The qualitative immunoenzymatic determination of IgM-class antibodies against Mycoplasma pneumoniae is based on the ELISA (Enzyme-linked Immunosorbent Assay) technique. Microtiter strip wells are precoated with Mycoplasma pneumoniae antigens to bind corresponding antibodies of the specimen. After washing the wells to remove all unbound sample material horseradish peroxidase (HRP) labelled anti-human IgM conjugate is added. This conjugate binds to the captured Mycoplasma pneumoniae-specific antibodies. The immune complex formed by the bound conjugate is visualized by adding Tetramethylbenzidine (TMB) substrate which gives a blue reaction product. The intensity of this product is proportional to the amount of Mycoplasma pneumoniae-specific IgM antibodies in the specimen. Sulphuric acid is added to stop the reaction. This produces a yellow endpoint colour. Absorbance at 450 nm is read using an ELISA microwell plate reader.
Storage and Stability	The reagents are stable up to the expiry date stated on the label when stored at 2-8C.
