– Ingezim® ASF CROM Ag is an immunochromatographic assay for the detection of ASFV in blood samples. The test is based on the use of two different coloured latex microspheres: black microspheres that are coated with a specific MAb to ASFV, and blue microspheres, which are used as test control.On the membrane, two lines are printed: the test line (T) has a specific MAb to ASFV and the control line (C) has a specific MAb for the control protein.If the case of a positive sample, the virus binds to the black beads conjugated to an anti-ASFV MAb. The immune complex then migrates through the membrane by capillarity and is captured again by the anti-AFSV MAb absorbed on the test line, resulting in the appearance of a black line. The presence of the control line serves as validity of the test, indicating that the immunochromatography has been performed correctly.
