Learn about our precisely quantitated microbial reference materials for streamlining microbial quality control testing.

ATCC has developed titered mycoplasma reference standards for comparing PCR and culture-based detection methods, and quantitative mycoplasma DNA certified reference materials for use as external controls in inclusivity/exclusivity testing and establishing limits of detection.

ATCC provides pharmaceutical testing labs with the top-quality, fully characterized strains needed to maintain the highest levels of product integrity and reputation.

ATCC provides an extensive array of authenticated and clinically relevant materials for evaluating limit of detection, inclusivity, and cross-reactivity.

Spike-in standards provide an easily detectable internal control that enables the optimization of a microbiome workflow and permits the normalization of data generated during 16S rRNA and shotgun metagenomic sequencing assays.

With more than a century’s worth of expertise in biomaterials handling, storage, and authentication, ATCC has the credible tools needed to support your QC programs.

NGS standards with known compositions are essential for ensuring assay optimization and data reproducibility throughout each stage of the workflow—from sample collection to data analysis

ATCC pneumococcal polysaccharides are available in three package sizes and new lots will be provided with a Certificate of Analysis that will include identity by NMR, residual protein, antigenicity, and molecular weight.

In this study, we evaluate the use of green fluorescent protein (GFP)-labeled strains representing several clinically relevant Shiga toxin-producing Escherichia coli (STEC) serogroups associated with foodborne disease as positive controls.
