    Immunoaffinity Column for 2-in-1 Comb Zearalenone and Fumonisins

    The immunoaffinity column can selectively adsorb zearalenone (ZEN) and fumonisin (FB1, FB2, FB3) from the sample solution, thereby having a highly targeted purification effect on the sample. The sample solution that has been purified by passing through the affinity column can be directly used for HPLC analysis or for LC-MS/MS analysis after concentrating with nitrogen gas and resuspended.

     

    1. Principle:

    The basis of the measurement is the antigen-antibody reaction. Antibodies are connected to the column and the Vomitoxin in the sample is extracted, filtered, and diluted, and then passed slowly through the Vomitoxin immunoaffinity column. The toxins bind to the antibodies in the column and the immunoaffinity column is then washed to remove other unrelated substances that have not been bound. The toxins are then eluted with eluent and injected into an analytical instrument for detection.

    ---- Air-pressure controller bracket

    ---- Air pump

    ---- Balance with 0.01g readability

    ---- High-speed homogenizer (maximum speed> 10,000 r/ min) or shaker

    ---- Grinder

    ---- Sieving screen:2-mm

    ---- Graduated cylinder: 100 mL/10 mL

    ---- Funnel: 50 mL

    ---- Syringe: 10 mL/20 mL

    ---- Pipette: 1 mL and pipette tips

    ---- Homogenization flask (or 250-mL conical flask with pestle)

    ---- Sample bottles and tubes

    ---- Rapid qualitative filter paper

    ---- Microfiber filter paper (e.g. Whatman 934-AH)

    ----Column holder and syringe connector plug (for use with immunoaffinity columns)

    3.2 Reagents

    ----Methanol (CH3OH): Chromatographic grade

    ---- Acetic acid (CH3COOH): Chromatography Grade

    ---- Acetonitrile (CH3CN): Analytical Grade

    ---- Ammonium acetate: Chromatography Grade

    ---- Sodium chloride (NaCl): Analytical Grade

    ---- TWEEN-20 (C58H114O26): Analytical Grade

    ---- Sodium hydroxide (NaOH): Analytical Grade

    ---- Hydrochloric acid (HCl): Analytical Grade

    ---- Distilled/deionized water

    1. Note:

    ---- Allow the immunoaffinity column to return to room temperature(22 to 25°C) before use.

    ---- The affinity column should be stored at 2 to 8°C, do not freeze.

    ---- Dot use any expired immunoaffinity column.

    ---- The sample volume can be increased or decreased appropriately as required, and the volume of the extraction solution should be adjusted accordingly.

    ---- Column capacity

    Toxin nameColumn Capacity: ng
    ZEN2000
    FB15000
    FB2
    FB3

    When the content of the toxin in the sample divided by the dilution factor is higher than the column capacity, it is necessary to reduce the volume of the sample solution appropriately, and retest.

    ---- The pH of the loading solution of the affinity column should be within the range of 6 to 8. If it deviates from this range, the pH should be adjusted with dilute hydrochloric acid or dilute sodium hydroxide.

    ---- Maintaining consistency (such as polarity, pH, and concentration) between the test solvent loaded into any analytical instrument and the mobile phase can help eliminate any adverse solvent effects.

    ---- WARNING: Zearalenone and Fumonisins are toxic and carcinogenic; protective equipment such as gloves and masks should always be used during handling.

    ---- Vessels and tools used to handle toxin solutions should be completely immersed in a sodium hypochlorite solution (5% v/v) overnight.

    ---- Ensure the LC-MS/MS is clean and the tubing is primed  appropriately for each run.

    ---- Follow appropriate instrument precautions if using HPLC.
