Tests & Reagents

Sigma-Aldrich offer a wide selection of test and reagents for pathogen detection, identification, and confirmation.

Test for Classic Biochemical Methods
Classical reagents, kit systems or convenient discs and strips can be used in the identification and confirmation of microorganisms. Based on rapid screening methods like the detection of enzymes with chromogenic substrates, indicators, or on complex building reactions, they are faster and easy to use. Also, the sensitivity to certain inhibitory substances can be used to identify organisms.

Test Kits for Innovative Molecular Biological Methods
HybriScan rapid test kits are based on an rRNA sandwich hybridization system which is less expensive and more robust than PCR methods. They are also more accurate (only detects living cells), quicker (time savings of up to 10 days over cultivation-based assays), and can be performed with standard laboratory equipment. These kits can be used for the identification and quantification of spoilage and pathogenic microorganisms in foods and beverages. They are ideal for the comprehensive and reliable routine control of raw materials and concentrates in all production steps, up to the quality check of finished goods.

Test Kits for Innovative Immunological Methods
The easy-to-use Staphylo Monotec Test Kit Plus is a rapid agglutination test for differentiation between Staphylococcus aureus and other Staphylococcus. With this kit, three characteristic properties (coagulase, protein A, and capsular serotype 5 polysaccharide) of S. aureus can be detected in one step with high reliability. This results in increased sensitivity and specificity in detecting methicillin resistant Staphyloccocus aureus.
