Specific sample purification

Sample preparation is an essential part of drug residue testing irrespective of the method being used (GC-MS, HPLC or ELISA).  To complement our range of drug residue ELISA kits, we have developed a number of immunoaffinity columns to provide a very effective sample clean up.

All Randox immunoaffinity columns contain immobilised antibodies and work by specifically binding and removing the target analyte from a variety of different sample types enabling analysis by ELISA or HPLC.

Randox Immunoaffinity columns offer the following benefits:

• Highly specific and efficient means of sample purification
• Suitable for use with ELISA, GC-MS, LCMS and HPLC
• Higher analyte recovery than other methods
• Safe – only one solvent elution step involved reducing the use of organic solvents              and waste disposal costs
• Fast – few purification steps
• Convenient – available in packs of 5 containing all necessary buffers required for   column storage and equilibrium
• Cost-effective – each column can be used up to ten times
• Long shelf life – 2 years shelf life from the date of manufacture
• Can easily be automated

Immunoaffinity columns are available for the following:

• Clenbuterol / ß-agonists
• Corticosteroids
• Trenbolone and nortestosterone
• Stilbene
• Zeronal
