Products
Isothermal amplification molecular kit with lateral-flow detection (SARS-CoV-2 example)
Molecular diagnostic kit combining isothermal loop amplification of viral RNA with lateral-flow immunochromatographic detection for visual readout; intended for use with purified RNA from respiratory samples.
Indirect ELISA for combined detection of IgM/IgG against multiple E. coli serogroups
Indirect ELISA employing recombinant glycoprotein antigens to detect IgM and IgG responses against multiple Escherichia coli serogroups for serodiagnosis and epidemiological serotyping.
Indirect ELISA for Trypanosoma cruzi (Chagas) IgG
Indirect ELISA using a panel of recombinant antigens for detection of IgG antibodies against Trypanosoma cruzi in serum and plasma for screening and confirmatory applications.
Antigen-detecting lateral-flow cassette for Dengue NS1
Single-step immunochromatographic cassette for qualitative detection of Dengue NS1 antigen in serum, plasma and venous or capillary whole blood with a 15-minute read time; uses highly specific monoclonal antibody reagents for early detection.
Multiplex lateral-flow cassette for Dengue (NS1 + IgM/IgG)
Two-in-one lateral-flow cassette combining NS1 antigen detection and IgM/IgG antibody detection to cover acute and convalescent stages of dengue infection with a single rapid test (15 minutes).
Veterinary indirect ELISA for Brucella (serum and milk)
Indirect ELISA for detection of anti-Brucella IgG in bovine serum and milk using recombinant glycoprotein antigens; configured to accept serum and milk matrices and to assist differentiation from certain vaccines.
