The TRUSTwell Syphilis Ab ELISA Test is a solid phase enzyme linked immunosorbent assay based on the principle of the double antigen sandwich technique for the detection of antibodies to Tp in human serum or plasma. The TRUSTwell Syphilis Ab ELISA Test is composed of two key components: 1) Solid microwells pre-coated with recombinant Tp antigens; 2) Liquid conjugates composed of recombinant Tp antigens conjugated with horseradish peroxidase (HRP-Tp conjugates).

 During the assay, the test specimen and HRP-Tp conjugates are incubated simultaneously with the coated microwells. Antibodies (IgG, IgM, or IgA) to Tp if present in the specimen, reacts to the Tp antigens coated on the microwell surface as well as the HRP-Tp conjugates, forming sandwich complex conjugates. Unbounded conjugates are then removed by washing. The presence of the complexed conjugates is shown by a blue color upon additional incubation with TMB substrate. The reaction is stopped with Stop Solution and absorbances are read using a spectrophotometer at 450 /620-690 nm.



All reagents except the concentrated wash buffer are ready bo use as supplied. Return all reagents requiring refrigeration immediately after use. Resealthe microwells after removing the desired number of wells. Ensure that the reagents are brought to room temperature before opening. All the reagents are stable through the expiration date printed on the label if not opened. Do not freeze the kit or expose the kit over 8C
