Immuonassays in Food Technologies and Food Testing

PerkinElmer is a pioneer in the food and feed safety testing industry, developing, manufacturingand marketing an extensive range of test kits to detect veterinary drug residues, antibiotics, pathogens, hormones, natural toxinsand various industrial contaminants found within the global food chain.

The company aims to offer food producers, processorsand government agencies high-quality test kits that facilitate compliance with local and global regulations to produce safe food for their customers.

Listed below are the highlights of PerkinElmer’s food and feed safety product line:

MaxSignal^® ELISA kits with some of the most sensitive tests available and providing a wide range of solutions for any customer

AuroFlow™ branded rapid lateral flow devices that enable customers to test for antibiotics in raw milk within 7 minutes, with little or no equipment

The Solus Pathogen Detection System offers highly efficient and powerful assays to detect Listeria, Salmonellaor E. coli O157. All assays have been validated by external independent laboratories to AFNOR 16140 and/or certified by the AOAC Performance Tested Method program.

AOAC-approved kit to detect histamine within 15 minutes from sample to results

PerkinElmer’s quality management system has been certified to ISO 9001 standards, and the company strives to deliver high-quality products and services together with excellent technical support and customer service.

Immunoassays in Food Technologies

MaxSignal ELISA in Food Testing

The MaxSignal ELISA Kits from PerkinElmer offer the widest array of competitive enzyme immunoassays for the quantitative analysis of mycotoxins, antibioticsand various other residues in food.

MaxSignal ELISAs feature high recovery rates, high reproducibilityand ready-to-use standards that avoid the need for dilution; thus, they are an economical, sensitiveand rapid method to test meat, dairy, seafood, poultry, feed, grainand more.

Validation of the MaxSignal Histamine Enzymatic Assay for the Detection of Histamine in Fish

Seafood processors use histamine testing as a control strategy in Hazard Analysis and Critical Control Points (HACCP). There is a high demand for a histamine detection method that integrates simple extraction with high-accuracy quantification.

The MaxSignal^® Histamine Enzymatic Assay Kit is a powerful enzyme-based assay that uses a simple aqueous extraction with high recovery in a wide range of fish samples like pouched tuna, fresh/frozen tuna, mahi-mahiand canned tuna.

MaxSignal Ractopamine ELISA Verification Report

In different parts of the world in placessuch as China and Europe, the use of ractopamine as a livestock growth promoter has been banned.

Preventing the entry of ractopamine residues into the food chain requires both producers and government surveillance agencies to use technologies and methods that can offer accurate, fastand reliable detection at particular sensitivities.

The MaxSignal^® Ractopamine ELISA Kit allows food manufacturers, government agenciesand quality assurance organizations to detect ractopamine in concentrations as low as 0.1 ng/g or 0.1 ppb in a wide range of sample types. An optimized sample preparation protocol was created and validated for swine feed in this study.

High-Throughput Screening Solutions for Nitrofurans and Chloramphenicol in Shrimp Samples

Many countries and organizations around the world have regulated the use of nitrofurans, a family of broad-spectrum antibiotics used extensively in the aquaculture industry and their metabolites, due to their detrimental effects on human health.

ELISA assays are extensively applied to detect chloramphenicol and nitrofuran metabolites for regulatory compliance due to the high selectivity, sensitivityand user-friendly nature of the method.

The precision and accuracy (CCß validation study) of the simultaneous 5-in-1 sample extraction technique through manual ELISA and DS2 automation methods have been demonstrated. The sensitivity of the assay kits (LOD) has also been exhibited with manual and DS2 methods.

Lastly, sample variability testing was conducted to characterize the effects of matrix from different shrimp sources.
