Reference loci for RT-qPCR analysis of differentiating human embryonic stem cells [PDF]

open access: yes, 2013
Background: Selecting stably expressed reference genes is essential for proper reverse transcription quantitative polymerase chain reaction gene expression analysis. However, this choice is not always straightforward. In the case of differentiating human

Assessment of common housekeeping genes as reference for gene expression studies using RT-qPCR in mouse choroid plexus

open access: yesScientific Reports, 2021
Choroid plexus (ChP), a vascularized secretory epithelium located in all brain ventricles, plays critical roles in development, homeostasis and brain repair. Reverse transcription quantitative real-time PCR (RT-qPCR) is a popular and useful technique for

Quick assessment of influenza a virus infectivity with a long-range reverse-transcription quantitative polymerase chain reaction assay

open access: yesBMC Infectious Diseases, 2020
Background The polymerase chain reaction (PCR) is commonly used to detect viral pathogens because of its high sensitivity and specificity. However, conventional PCR methods cannot determine virus infectivity.

Angiopoietins differentially influence in vitro angiogenesis by endothelial cells of different origin [PDF]

open access: yes, 2011
Angiopoietins are important growth factors for vascular development and quiescence. They are promising targets for pro-or anti-angiogenic therapies in diverse pathologies, but the mechanisms of the ANGPT/TIE2 system are complex and not well understood ...

40 minutes RT-qPCR Assay for Screening Spike N501Y and HV69-70del Mutations

open access: yesbioRxiv, 2021
A one-step reverse transcription and real-time PCR (RT-qPCR) test was developed for rapid screening (40 minutes) of the Spike N501Y and HV69-70del mutations in SARS-CoV-2 positive samples.

Stem‐Loop RT‐qPCR for miRNAs [PDF]

open access: yesCurrent Protocols in Molecular Biology, 2011
AbstractThis unit presents a specific and sensitive quantitative reverse‐transcription PCR (RT‐qPCR) method for measuring individual microRNAs (miRNAs) in tissue or cultured cells. miRNAs are 17 to 24 nucleotides (nt) in length. Standard and quantitative PCR methods require a template that is at least two times the length of either of the specific ...
