MDx-Chex for Blood Culture Yeast (RUO), MDx-Chex for Blood Culture GP (RUO) and MDx-Chex for Blood Culture GN (RUO) are full-process molecular quality controls designed for comprehensive molecular assay workflow validation.

The Streck ARM-D kit, ampC is a multiplex real-time PCR kit for the rapid detection of AmpC β-lactamase resistance genes in Gram-negative bacteria. This comprehensive kit allows you to detect over 200 ampC allelic variants in the clinically relevant resistance gene families, CMY02, DHA, ACC, EBC, FOX and MOX, and differentiate between plasmid-mediated and chromosomal AmpC β-lactamase resistance. 

The Streck ARM-D Kit, TEM/SHV/GES is a multiplex real-time PCR kit for the rapid detection of antibiotic resistance genes in Gram-negative bacteria. This comprehensive kit allows you to detect over 350 allelic variants in the TEM, SHV and GES extended-spectrum β-Lactamase gene families. 

MDx-Chex for BCID2 is a first-of-its-kind quality control designed to evaluate the entire analytical process of the BIOFIRE ® Blood Culture Identification 2 (BCID2) Panel for sepsis. With MDx-Chex for BCID2, you can track lot-to-lot performance of the BCID2 assay and reduce the occurrence of incorrect results due to instrument or assay failures. 

Cell-Free DNA BCT is a blood collection tube that stabilizes cell-free DNA for up to 14 days at 6 °C to 37 °C* and CTCs for up to 7 days at 15 °C to 30 °C*. It is available as a CE marked in vitro diagnostic device or as a Research Use Only tube, depending on region of use.  *These performance characteristics have not been evaluated by the U.S. Food & Drug Administration

Solutions for your individual requirements

Bovine serum albumin (BSA) is used extensively as a carrier protein to dilute antibodies and as a general protein blocking agent in immunoassays and immunodetection protocols. Our IgG-free BSA, which is also protease-free, should alleviate many of the problems associated with using BSA. Many preparations of BSA, even some of the highest purity grades, contain IgG that may become an antigen for cross-reacting secondary an…

ChromPure is our trade name for highly purified proteins from the serum of non-immunized animals.

Antisera to Enzymes, Serum Proteins, & Whole Serums. Polyclonal antisera from immunized hosts are lipid extracted to improve clarity, salt fractionated, dialyzed against phosphate buffered saline containing sodium azide, and freeze-dried. Antisera against whole serums are obtained by immunizing host animals with whole serum. Antisera against whole IgG molecules [i.e. Anti-IgG (H+L)] are recommended for bridging PAP to prima…

Solid-Phase Immunoadsorbent Gels. Highly purified IgG from the serum of non-immunized animals is coupled to cyanogen bromide-activated 4% agarose gels for use in preparing affinity-purified antibodies or removing cross-reactive antibodies. Proteins are coupled at a concentration of 1 mg protein per ml of settled gel, and are packaged in phosphate buffered saline with sodium azide.

Peroxidase-Anti-Peroxidase (PAP) Soluble Immune Complexes. Whole antisera against IgG (H+L) are recommended for bridging PAP to primary antibodies. Antisera against IgG (H+L) or against the F(ab') 2 fragments of IgG will also bridge PAP to IgM primary antibodies (such as IgM monoclonal antibodies) by virtue of common light-chain recognition.

Threefold power for maximum flexibility in PCR. The thermal cycler Biometra TRIO provides three independent sample blocks which can run three different PCR reactions in parallel. The instrument is available with different sample blocks: 3x48 well for 0.2 ml tubes, 3x30 well for 0.5 ml tubes or 3x combi block for 48 well 0.2 ml tubes or 18x0.5 ml tubes each. Thus, this thermocycler offers high throughput in parallel operatio…
