● Prolex™ Latex Agglutination Reagents: Rapid latex agglutination systems for detection/identification of Streptococcus, Staphylococcus (including MRSA), E. coli, and Legionella.
● Microbank®: A ready-to-use system designed to simplify the storage and retrieval of bacterial and fungal cultures. Microbank® 2D barcoded cryovials provide a more reliable preservation approach than repeated subculturing, helping prevent contamination, strain loss, or phenotypic changes. The specially formulated cryoprotective fluid supports longer survival of fastidious organisms and improves quantitative recovery.
● Salmonella Antisera: Diagnostic antisera with long shelf life and economical per-test usage for identification and serotyping of Salmonella strains, providing a comprehensive panel for slide agglutination testing.
● Shigella Antisera: Produced in accordance with WHO standards, offering a comprehensive diagnostic panel for slide agglutination testing.
● Prolisa™ ELISA Test Kits: Prolisa™ Clostridioides difficile GDH Enzyme Immunoassay is a microplate-based assay for the qualitative detection of C. difficile glutamate dehydrogenase (GDH) in stool specimens. It is intended for use as an aid in the diagnosis of C. difficile infection (CDI).
● Proflow™ Lateral Flow Tests: Rapid, sensitive tests for multiple pathogens with results in about 15 minutes and simplified operation. Example: Proflow™ C. difficile GDH is a rapid, qualitative lateral flow immunochromatographic assay for detecting GDH antigen in stool. GDH in the specimen reacts with anti-GDH antibodies (colloidal gold conjugate), migrates by capillary action, and is captured by immobilized anti-GDH antibodies at the test line—appearance of a visible test line indicates a positive result.
● Pro-Stains™ Staining Reagents & Immersion Oil: A broad range of ready-to-use and concentrated staining reagents made from high-quality raw materials, with strict QC and filtration to ensure consistent staining performance.
● Mucolyse™ Sputum Digestion Reagent: A convenient, economical, and safer sputum digestion format. Each vial contains a pre-measured amount of lyophilized dithiothreitol (DTT) and phosphate buffer; reconstitute with 10 mL sterile water, then dilute further to prepare 100 mL of active digestion solution.
● TestOxidase™: A rapid oxidase test reagent for determining bacterial cytochrome oxidase. Ready to use; contains 0.3% N,N,N′,N′-tetramethyl-p-phenylenediamine (TMPD) in 0.003 M buffer with reducing agents and organic stabilizers. Suitable for room-temperature storage and on-demand use.
● Rabbit Coagulase Plasma (Lyophilized): A standard citrated, lyophilized plasma reagent used to detect coagulase produced by Staphylococcus aureus.
