Launch of SENSIPure Immunoaffinity Column with Extended Quality Control


We are pleased to announce the launch of the SENSIPure Immunoaffinity Column Aflatoxins Total for sensitive and reliable sample purification for total aflatoxin quantification. A crucial step in sample preparation is purifying the extract with the immunoaffinity column. After the extract has been applied to the column and washing and elution have taken place, the product is an enhanced and purified extract, which improves measurement quality.

The SENSIPure columns provide a highly specific purification with monoclonal antibodies and can be applied for a wide range of matrices. The columns are robust with a good flow behaviour and have a shelf lifetime of 2 years.

In addition to quantifying the capacity and the cross-reactivity, the extended quality control includes inspecting blank contamination and verifying recovery in matrix.

Aflatoxin outbreaks
Aflatoxin is a serious health concern and outbreaks globally occur multiple times a year. Just recently, children’s rice cakes were recalled in Hungary and other European countries because they were suspected of containing hepatotoxic and carcinogen Aflatoxins.[1,2] Aflatoxins are mycotoxins produced by the fungi Aspergillus flavus and Aspergillus parasiticus pre and/or post harvesting.[2]

This is not an isolated case. Since the beginning of this year there were 212 notifications in the RASFF (Rapid Alert System for Food and Feed) related to aflatoxins in foodstuffs.[3]

Screening for aflatoxins: the importance of IAC
To prevent a recall of raw or finished products and to protect human and animal health from aflatoxins exposure, Gold Standard Diagnostics has a portfolio of diagnostics solutions for aflatoxin B1 and total aflatoxins screening. The SENSIPure IAC Aflatoxins Total is a novel immunoaffinity column containing monoclonal antibodies that purify and clean the food or feed extracts before measurement via LC-FLD or LC-MS/MS. The SENSIPure IAC Aflatoxins Total total was used in a common method validation for Aflatoxin B1, B2, G1 and G2 covering the key matrix groups grains, nuts, dried fruits, spices and feed. These studies were shown to be robust when using the columns with a manual or automated sample cleanup.
