Norovirus is the leading cause of epidemic and endemic acute gastroenteritis worldwide; it is also the leading cause of foodborne disease outbreaks. This virus genus has many characteristics making it perfect foodborne pathogen including low infectious dose, high transmissibility, environmental persistence and resistance to many commonly used disinfectants and sanitizers.
Dr. María Vega Almazán and co-workers from different Pediatric, Clinical Diagnostic and Research Units from Granada and Cordoba (Spain) published an interesting article studying the prevalence of subclinical celiac disease (CD) and analyzing the diagnostic yield of a new rapid test in children aged 2–4. Our Simple CD2WB immunochromatographic test strip was used in this study being an excellent diagnostic screening tool with high sensitivity and negative predictive value.
PapillomaStrip test is a test based on the reverse blot technique that allows qualitative detection in DNA samples from cervico-uterine smears or biopsies, of 37 human Papillomavirus subtypes:
Medium-high risk: 16, 18, 26, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66, 68, 69, 73 and 82 (MM4 e IS39).
Low risk: 6, 11, 40, 42, 43, 44, 54, 61, 62, 67, 70, 71, 72, 74, 81, 83, 84 y 91.
The OPERON Norovirus test is a chromatographic immunoassay for the qualitative detection, in separate bands, of Genogroup I (GI) and Genogroup II (GII) of Norovirus in human faeces.
The test is based on the immunological capture of coloured microbeads during its moving along a membrane on which specific monoclonal antibodies against GI and GII have been immobilized in two separate bands.
OPERON's GDH immunochromatographic assay is a rapid test for the qualitative detection of glutamate dehydrogenase (GDH) from Clostridium difficile in human stool samples. A positive signal in the test indicates the presence of C.difficile in the stool sample. Subsequent analysis of the sample with a test for detecting C.difficile toxins (such as OPERON's 2A-Bdiff test) confirms whether the strain is toxigenic and, therefore, pathogenic and disease-causing.
B27 OligoGen is a test designed for the qualitative detection of HLA B*27 alleles through the amplification of an specific genomic region and its subsequent identification by oligo-immunochromatography. The procedure of B27 OligoGen kit consists in three steps:
a) DNA extraction
b) amplification by PCR
c) hybridization and developing
The CeliacStrip test is an assay that allows the identification of the main HLA haplotypes associated with celiac disease.
The test detects the presence or absence of haplotypes that encode HLA-DQ2 and HLA-DQ8:
HLA - DQ2 cis: DQA1*05 - DQB1*02 - DRB1*03
HLA - DQ2 trans: DQA1*05 - DQB1*0301 - DRB1*11/DRB1*12 - DQA1*02 - DQB1*02 - DRB1*07
HLA - DQ8: DQA1*03 - DQB1*0302 - DRB1*04
Immunochromatographic test for the qualitative detection of casein glycomacropeptide (cGMP) in milk. The cGMP is produced by enzymatic or bacterial induced degradation of the casein present in milk. This degradation takes place during the cheese manufacturing process, where specific proteases are added to act on the milk casein. Therefore its presence in milk is an indication of milk adulteration with whey.
The YChromStrip test is a test for the detection of deletions in the Azospermia Factor (AZF) located on chromosome Y. These deletions are the cause of male infertility due to azospermia (absence of sperms) or oligospermia (low sperm count).
The test detects the presence or absence of six STSs (sequence tagged sites) located in three different regions of the Azoospermia Factor: AZFa (sY84 and sY86), AZFb (sY127 and sY134) and AZFc (sY254 and sY255).
A new immunochromatographic (IC) rapid tests for the detection of suspected hyper-virulent strains (O27 or O17) of Clostridium difficile von Eichel-Streiber C., Murillo R. and Villacampa M. and tgcBIOMICS GmbH, Carl-Zeiss Str. 51, D-55129 Mainz, Germany OPERON S.A.
