APPLIED SCIENCES
Founded in 2007, BioGX’s core focus included the development of molecular diagnostics panels for Food Safety, Water Quality and Pharmaceutical Quality Control. Since then, the company has established itself as a leader in this field, holding one of the largest portfolios of infectious disease panels worldwide.
WATER QUALITY
The BioGX Sample-Ready™ technology, one-tube reagent approach is available for ruminant and porcine origin confirmation for food, pharmaceutical and drinking water safety.
Cattle Feed Contamination
BioGX offers a unique reagent that detects ruminant DNA (bovine, caprine, and ovine) in cattle feed. This reagent has been independently evaluated using very strict performance criteria and was recently converted to the BioGX Sample-Ready™ lyophilized format. The reagent is now utilized as part of an official method in many government laboratories, including the US FDA. Note: this reagent has only been validated on the Cepheid SmartCycler II.

Abstract: The U.S. Food and Drug Administration (FDA) has previously validated a real-time PCR-based assay that is currently being used by the FDA and several state laboratories as the official screening method. Due to several shortcomings to the assay, a multiplex real-time PCR assay (MRTA) to detect three ruminant species (bovine, caprine, and ovine) was developed using a lyophilized bead design. The assay contained two primer or probe sets: a “ruminant” set to detect bovine-, caprine-, and ovine-derived materials and a second set to serve as an internal PCR control, formatted using a lyophilized bead design. Performance of the assay was evaluated against stringent acceptance criteria developed by the FDA’s Center for Veterinary Medicine’s Office of Research. The MRTA for the detection of ruminant DNA passed the stringent acceptance criteria for specificity, sensitivity, and selectivity. The assay met sensitivity and reproducibility requirements by detecting 30 of 30 complete feed samples fortified with meals at 0.1% (wt/wt) rendered material from each of the three ruminant species. The MRTA demonstrated 100% selectivity (0.0% false positives) for negative controls throughout the assessment period. The assay showed ruggedness in both sample selection and reagent preparation. Second and third analyst trials confirmed the quality of the written standard operating procedure with consistency of results. An external laboratory participating in a peer-verification trial demonstrated 100% specificity in identifying bovine meat and bone meal, while exhibiting a 0.03% rate of false positives. The assay demonstrated equal levels of sensitivity and reproducibility compared with the FDA’s current validated real-time PCR assay. The assay detected three prohibited species in less than 1.5 h of total assay time, a significant improvement over the current real-time assay. These results demonstrated this assay’s suitability for routine regulatory use both as a primary screening tool and as a confirmatory analysis.

Abstract: A real-time PCR assay was developed for the determination of ruminant material in porcine-derived crude heparin products. The assay consists of a bead format with lyophilized primers and probe sets that identify ruminant (bovine, ovine, caprine) and porcine material and also contain an internal amplification control. The assay was verified by two analysts: the first located at the FDA and the second at an independent State laboratory. Performance of the assay was evaluated against stringent acceptance criteria developed by the U.S. FDA’s Center for Veterinary Medicine’s Office of Research. The heparin Multiplex Real-Time Assay (hMRTA) for the detection of ruminant DNA in porcine crude heparin passed the stringent acceptance criteria for specificity, sensitivity, and selectivity. The assay met sensitivity and reproducibility requirements previously established by the multiplex real-time PCR assay (MRTA) for detection of ruminant animal material in feed. The hMRTA, when used in porcine crude heparin, exhibited 98% sensitivity, 98% true positives, 2% false negatives. This multiplex PCR-based assay detects three ruminant species, verifies porcine origin and could be used as a screening tool or as a confirmatory assay. It is capable of providing additional assurances of crude heparin quality and will help to identify and control the species origin of the heparin supply. The control of the animal origin of crude heparin is important to ensure the safety of drugs and devices that contain heparin and to protect public health.
