Four vials of Streck MDx-Chex molecular quality controls are arranged in two pairs on a white background. The pair on the left is labeled "BC-GN" and includes vials with white and red caps. The pair on the right is labeled "BC-GP" and includes vials with white and black caps. These controls are used for Gram-positive and Gram-negative sepsis testing.

Product Description

MDx-Chex for BC-GP and BC-GN are patient-like full process controls designed to validate the entire analytical process of the Luminex VERIGENE BC-GP and BC-GN Panels, including automated nucleic acid extraction, DNA purification, hybridization of target DNA to the microarray, hybridization of gold nanoparticles to target DNA and silver staining of hybridized probes. MDx-Chex for BC-GP and BC-GN cover all targets tested with Luminex VERIGENE for BC-GP or BC-GN, respectively. Microorganisms are intact, inactivated and…
