This document specifies a rapid colloidal gold immunochromatographic detection method for indoxacarb residues in vegetables and fruits. This document is suitable for the rapid detection of indoxacarb residues in vegetables and fruits. Note 1: Vegetables include cabbage, cauliflower, broccoli, kale, sprouts, spinach, cabbage, leaf lettuce, head lettuce, Chinese cabbage, nightshade vegetables, and cowpeas. Note 2: Fruits include pears, stone fruits, bilberries, grapes, and kiwis. This method adopts the principle of competitive inhibition immunochromatography. Indoxacarb in the sample is extracted and binds to the colloidal gold-labeled specific antibody, inhibiting the binding of the antibody to the antigen on the test line (T line) in the test strip, resulting in a change in the color of the test line (T line). . By comparing the color depth of the test line (T line) and the quality control line (C line), a qualitative analysis of indoxacarb in the sample was performed.
