PRINCIPLE OF METHOD This assay is a one-step lateral flow two-site sandwich chromatographic immunoassay. The membrane is pre-coated with mouse anti-human sperm antigen monoclonal antibody on the test band region(T line) and goat anti-mouse IgG polycolonal antibody on the control band region(C line). When sample is added, the gold-antibody conjugate is rehydrated and sperm antigens interact with the gold conjugated antibodies. The antigen-antibody-gold complex then migrates towards the test window until the Test region (T) where it will be captured by immobilized antibodies, forming a visible pink line (Test band), indicating a positive result.
HOW TO READ THE RESULT Pay attention to the position of the Control Line(C) and Test Line (T). 1.POSITIVE RESULT: Two colored lines appear both one at the test line(T) and another at the control line(C). 2.NEGATIVE RESULT: Only one colored line appears in the Control line(C).No colored line in the Test line(T). 3.INVALID RESULT: Absence of a colored line in the control region is an invalid result. You should repeat the test with a new test device.
