Vitamin B12 (VB12) is an important nutrient, and its quality control in food crucial. In this study, based on the principle of specific recognition target analyte by monoclonal antibodies (mAbs), a time-resolved fluorescent microsphere immunochromatographic assay (TRFM-ICA) was developed to detect content VB12 infant formula milk powder. First, performance anti-VB12 mAb evaluated, revealing half-maximal inhibitory concentration 0.370 ng/mL, affinity constant 2.604 × 109 L/mol no cross-reactivity with other vitamins. Then, highly sensitive TRFM-ICA developed, visual limit detection 10 μg/kg cut-off value 100 for qualitative range 4.125–82.397 quantitative detection. addition, test results real samples were consistent quantification using microbiological methods, coefficient variation less than 10%, showing good accuracy stability, confirming that suitable analysis powder samples. (mAbs) against VB12, fluorescence converting biological signals into optical signals.
