Description

Product Name: Chlamydia trachomatis IgA ELISA

# of Samples: 1 x 96 Assays

Intended Use: The Chlamydia trachomatis IgA-ELISA is intended for the qualitative determination of IgA class antibodies against Chlamydia trachomatis in human serum or plasma (citrate).

Introduction: Chlamydiae are nonmotile, Gram negative and obligatory intracellular growing bacteria which form characteristic inclusions within the cytoplasm of parasitized cells. They are easily visible in the light microscope. Three different Chlamydia species pathogenic for humans are known: Chlamydia trachomatis, Chlamydia pneumoniae and Chlamydia psittaci, and one species only pathogenic for animals (C. pecorum). Chlamydia trachomatis is the most prevalent agent of sexually transmitted diseases worldwide (400-500 million cases) and the number of infections is constantly growing, during childbirth, causing conjunctivitis or pneumonia in newborns. Untreated cases of chlamydial infection can lead to chronic salpingitis, possibly resulting in ectopic pregnancy or infertility. In males, C. trachomatis is a major cause of non-gonococcal urethritis.
A severe problem in Chlamydia infections is the frequent asymptomatic insidious course which may result in the initiation of chronic diseases. In many instances primary infections are not recognized and only the sequelae caused by ascended, persisting agents are diagnosed.
Infection may be identified by
Microscopy: Giemsa stain
PCR
Serology: Detection of antigens by ELISA
Detection of antibodies by IF, EIA, ELISA

Principles of the assay: The qualitative immunoenzymatic determination of IgA-class antibodies against Chlamydia trachomatis is based on the ELISA (Enzyme-linked Immunosorbent Assay) technique.
Microtiter strip wells are precoated with Chlamydia trachomatis antigens to bind corresponding antibodies of the specimen. After washing the wells to remove all unbound sample material horseradish peroxidase (HRP) labelled anti-human IgA conjugate is added. This conjugate binds to the captured Chlamydia-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 Chlamydia-specific IgA 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...8 °C.
