Currently, qPCR/RT-qPCR is regarded as the ‘gold standard’ for the quantitative analysis of nucleic acids and Meridian’s Lyo-Ready TM and Air-Dryable TM qPCR and RT-qPCR master mixes are the market-leading solution for molecular diagnostic assays requiring fast cycling, superior sensitivity, high inhibitor tolerance and ambient temperature stability. Lyo-Ready TM and Air-Dryable TM qPCR and RT-qPCR master mixes are 4x concentrated, glycerol-free and contain specialized excipients that are compatible with lyophilization or air-drying to create ambient-temperature stable assays, or they can be used as a wet mix. They are highly inhibitor-tolerant and ultra-sensitive making them ideal for point-of-care or machine-automated multiplexing assays. As ready-to-use mixes, they require no further optimization besides the addition of primers and probes. Within the Lyo-Ready TM and Air-Dryable TM range, Meridian offers universal inhibitor-tolerant qPCR and RT-qPCR formulations as well as Specimen-specific TM master mixes designed for crude blood, saliva, urine or stool samples. The universal mixes are highly resistant to various qPCR inhibitors and can be used across a range of patient sample types. The Specimen-specific TM range is more specialized and designed for inhibitor-rich samples or direct detection from a crude lysate, avoiding the need for DNA or RNA extraction and purification. These mixes are ultra-sensitive and are capable of detecting DNA down to a single copy and RNA down to 50 copies.
Product Features
• Available in universal or specimen-specific formulations for blood, saliva, urine or stool and suitable for direct detection assays using crude samples • High efficiency and sensitivity in multiplex reactions
• Just add primers and probes, no other optimization required • Shelf-life greater than 12 months after lyophilization or air-drying • Reduces cost and complexity of shipping and storage

Specimen-specific ™ qPCR & RT-qPCR Mixes
Blood-Specific Mixes
Blood
Blood is one of the most common specimens used for laboratory diagnostic testing and it is useful for evaluating the function of vital organs and for diagnosing diseases such as bacterial and viral infections, cancer (liquid biopsy), cardiovascular disease, and metabolic disorders including diabetes. However, there are several PCR inhibitors such as immunoglobulin G, hemoglobin, lactoferrin and leukocyte DNA that are present in blood which impact a reaction’s efficiency. In addition, anticoagulants used to stabilize blood samples (e.g., EDTA, citrate or heparin) contain a number of inhibitors which cause interference in a PCR reaction. Over the past decade, many diagnostic assays that use blood as a specimen have improved in terms of turnaround time, sensitivity and specificity as traditional techniques and biomarkers have been replaced by newer, faster and more sensitive methods. The traditional approaches to overcoming inhibition however have relied on removing inhibitors through DNA or RNA extraction prior to testing, but these methods are not 100% effective, cause sample loss, and reduce reproducibility.

Saliva-Specific Mixes Over the last decade, saliva has been extensively studied as a diagnostic specimen due to its non-invasive and simple sample collection/logistics and similar to serum, saliva contains hormones, antibodies, growth factors, enzymes, and microbes that can be used as biomarkers for disease detection. However, there have been challenges adopting saliva for molecular diagnostics due to the low concentration of analytes and high concentration of PCR inhibitors in saliva. Cumbersome sample preparation steps have been required to homogenize the specimen and adequately purify the DNA/RNA for molecular quantification. Meridian’s new Air-Dryable TM and Lyo-Ready TM direct saliva mixes are unique in that they have been designed to specifically overcome the inhibitors found in saliva or sputum samples. As a result, they are capable of highly sensitive amplification using crudely processed samples or extracted DNA or RNA in multiplex detection assays.

Stool-specific Mixes
Stool
PCR inhibitors found in stool specimens, such as bile salts, polysaccharides, hematin and catabolic substances, have posed serious challenges to developing assays that can directly amplify DNA or RNA. In addition, due to the high complexity and heterogeneity of fecal matter, sample preparation has traditionally been required to remove possible interfering substances such as food debris, microorganisms, desquamated epithelial cells and mucus from the specimen. Air-Dryable ™ and Lyo-Ready ™ Stool mixes are designed for direct amplification from stool samples, and require only minimal sample processing. The mixes contain an optimized blend of additives to negate inhibitor effects while maintaining the quality and integrity of the patient sample. As the need for fast, non-invasive testing for gastrointestinal conditions increases, short turn-around times, higher sensitivity and a long shelf-life become important distinguishing features.

Urine
Urine is an ideal clinical specimen because it is excreted in large quantities, non-invasive, and can be self-sampled. Currently, urine specimens are used in the diagnosis and management of infectious diseases (including STDs), hormone and metabolic disorders, renal diseases, bladder cancer, urinary tract infections (UTIs) and for monitoring recreational drug use. However, urine contains substances such as urea and nucleases that can damage DNA or inhibit a PCR reaction. Air-Dryable ™ and Lyo-Ready ™ urine mixes are inhibitor-
