Real-time quantitative PCR analysis of human low-density (LDNs) and normal-density neutrophils (NDNs)

ABSTRACT: NDNs and LDNs were isolated by density gradient centrifugation of PBMCs from 8 patients affected by tubercolosis (TB). In detail, RNA was extracted from NDNs and LDNs by Maxwell® RSC miRNA Tissue kit (Promega, Madison, USA), following manufacturer’s instructions. RNA concentration and quality was measured using NanoDrop 2000 Spectrophotometer (Thermo Fisher Scientific). Total RNA (600 ng) was reverse transcribed using the RT2 First Strand Kit (SABiosciences, Qiagen, UK). 84 human cytokines and chemokines were tested using the RT2 Profiler PCR Array Human Innate & Adaptive Immune Responses array (Qiagen). A semiquantitative real-time RT-PCR was performed using a real-time PCR detection system (QuantStudio 7 Flex Real-Time PCR System, Thermo Fisher Scientific) with a two-step thermal cycling: 95 °C for 10 min, followed by 40 cycles (95 °C for 15 sec, 60 °C for 1 min). Data were analysed using the RT² Profiler PCR Array Qiagen data analysis software, and ACTB and B2M as housekeeping genes.

Real-time quantitative PCR analysis of mouse lungs after exposure to early SARS-CoV-2 bearing 614G, Kappa or Delta variant

Project description:Age-matched K18-hACE2 transgenic mice were passively transferred with human COVID-19 mRNA post-vaccination (post-vac) sera followed by the lethal challenge with different SARS-CoV-2 viruses via intranasal route, including (1) New York-PV09158/2020 (NY) of lineage B.1.3 bearing 614G, (2) Kappa (B.1.617.1) and (3) Delta (B.1.617.2). Mouse lungs were harvested on 5 days post infection (dpi). Total RNA was extracted using QIAgen RNeasy Plus Mini Kit and was reverse transcribed using the High-Capacity cDNA Reverse Transcription Kit (Thermo Fisher Scientific). Resultant cDNA was used as the template along with RT2 SYBR Green ROX qPCR Mastermix (Qiagen) to perform RT² Profiler™ PCR Array Mouse Hypoxia Signaling Pathway (Qiagen) real-time PCR in Stratagene MX3000p qPCR system.

Urinary exosome microRNA signatures as a non-invasive prognostic biomarker for prostate cancer

Project description:We aimed to identify urinary exosomal miRNAs associated with PCa metastasis and develop a non-invasive risk-scoring model for PCa metastasis in this study. MiRNA profiles were examined using the Taqman low-density miRNA array (TLDA). Megaplex reverse transcription reactions and pre-amplification reactions were performed to increase the quantity of cDNA for miRNA expression analysis using the Megaplex PreAmp Primers Human Pool A and TaqMan PreAmp Master Mix (Thermo Fisher Scientific). MiRNA expression was evaluated via the TLDA panel A v2.0 (Thermo Fisher Scientific). Raw data were processed using the QuantStudio Real-Time PCR Software (Thermo Fisher Scientific) to determine a cycle threshold (Ct) value for each miRNA.
