Among the company's outstanding products, immunoaffinity columns are considered a breakthrough tool, particularly useful in the analysis of mycotoxins, prohibited substances, and complex biological compounds.
1. Introduction to immunoaffinity columns
R-Biopharm immunoaffinity columns are designed on the principle of antigen - antibody interaction. Specific antibodies are immobilized on a solid phase, usually agarose gel or polymer, allowing selective binding to target molecules such as aflatoxin, ochratoxin, fumonisin, or other compounds.
1.1. Key features
- High specificity: The antibodies on the column bind only to the target compounds, helping to remove as much interference from the sample as possible.
- High recovery efficiency: Optimized to ensure analyte recovery of 90–100%.
- Compatible with many sample types: the column can be used with complex samples such as cereals, milk, wine, processed foods, and animal feed.
- Easy to use: Simple procedure, already integrated into many testing protocols.
1.2. Application in mycotoxin analysis
- Mycotoxins are one of the largest groups of hazardous substances in food and animal feed. R-Biopharm immunoaffinity columns are designed to analyze common mycotoxins such as:
- Aflatoxin (B1, B2, G1, G2): Used in the testing of cereals, oilseeds, and dairy products.
- Ochratoxin A: Commonly analyzed in wine, coffee, and cereals.
- Fumonisin: Mainly in corn and corn products.
- Zearalenone: Testing in animal feed and cereals.
- Deoxynivalenol (DON): Associated with cereals and processed foods.
1.3. Benefits of using immunoaffinity columns
- Meets international standards such as AOAC, ISO and EU Regulations.
- Reduces analytical errors thanks to high sensitivity and the ability to remove background interference.
- Saves time thanks to a rapid procedure, usually taking only 30-60 minutes.
2. Procedure
- The procedure for using R-Biopharm immunoaffinity columns usually includes the following main steps:
- Sample preparation: Treat the sample with a suitable solvent (usually methanol or acetonitrile). Filter through a membrane filter to remove the residue.
- Load the sample onto the column: pour the sample solution through the immunoaffinity column. The analytes will bind to the antibodies on the column.
- Wash the column: wash the column with buffer solution to remove unrelated substances.
- Release the analyte: use the release solution (usually methanol) to recover the analyte.
- Quantitative analysis: analyze the released substance by HPLC, LC-MS/MS, or ELISA.
3. Featured product lines
