Syphilis (TP) ELISA Kits for Blood Bank Screening
Syphilis (TP) EIA Kit
Syphilis ELISA Kits, i.e. TP ELISA kits and Syphilis EIA kits are Enzyme-Linked Immunosorbent Assays for qualitative detection of antibody to Treponema Pallidum (TP) viruses in human serum or plasma specimen. TP ELISA test kits are widely used by blood banks to screen blood donors and as an aid for the diagnosis and management of clinical conditions known as syphilis. Atlas company would like to offer quality TP EIA kits at competitive prices.
With TP blood bank ELISA kit, the detection of TP antibodies is achieved by antigen "sandwich" enzyme-linked method (ELISA) where polystyrene microwell are pre-coated with recombinant Treponema pallidum antigens expressed in E. coli. The sample is added into microwells together with recombinant TP antigens conjugated to horseradish peroxidase (HRP-Conjugate). The pre-coated antigens express the same epitopes as the HRP-Conjugate antigens, but are expressed in different hosts. In case of presence of anti-TP in the sample, during incubation the pre-coated and conjugated antigens will be bound to the two variable domains of the antibody and the specific antigens-antibody immunocomplex is captured on the solid phase. After specific treatment with other reagents enclosed in these anti-Syphilis ELISA screening kits, the antigens-antibody immunocomplex will turn into yellow color, whose amount can be measured and is proportional to the amount of antibody in the sample. This indicate a positive result. Wells containing samples negative for TP antibody remain colorless.
