2026
This protocol includes a step-by-step workflow for calcified vascular specimens: tissue handling, decalcification, RNA validation, calcification level detection, and region-of-interest selection strategies on the Nanostring GeoMx Digital Spatial Profiler (DSP). The goal is to present a comprehensive method for preserving vascular tissue morphology and RNA for reliable spatial transcriptomic analysis.

Quantifying levels of HIV-1 RNA in plasma and sequencing single HIV-1 genomes from individuals with viral loads below the limit of detection (50-75 copies/ml) is difficult. Here we describe how to extract and quantify plasma viral RNA using a real time PCR assay that reliably measures HIV-1 RNA down to 0.3 copies/ml and how to amplify viral genomes by single genome sequencing, from samples with very low viral loads.

We describe a technique for profiling microRNAs in early mouse embryos. This protocol overcomes the challenge of low cell input and small RNA enrichment. This assay can be used to analyze changes in miRNA expression over time in different cell lineages of the early mouse embryo.
FAQs
A defined RNA concentration provides a reference point against which assay measurements can be evaluated. Comparing observed results with that reference helps determine whether an assay measures RNA consistently and supports meaningful comparisons between samples. In infection and immune-response studies, this calibration strengthens quantitative conclusions about pathogen RNA, host gene expression, cytokine responses, or other RNA-associated biomarkers.
Concentration alone does not establish what RNA material a measurement represents. Confirmed identity links the reference material to the intended target, while concentration supports quantitative comparison. Together, these characteristics help distinguish a genuine change in the measured target from an error caused by using an unsuitable reference, improving validation and interpretation of RNA-based assays.
Degradation can reduce the amount or quality of usable RNA, causing the reference to represent the target inconsistently over time or between preparations. Contamination can introduce unwanted material that compromises measurement accuracy. Controlled handling therefore focuses on limiting both problems so that prepared standards remain suitable for comparison, calibration, and validation in repeated experiments.
Preparation begins with obtaining RNA of the intended identity and concentration. The material is then assessed for quality before being converted into consistent dilutions for the planned measurements. Handling conditions should limit degradation and contamination throughout these stages. This sequence creates a controlled reference that can be used consistently rather than relying on an uncharacterized RNA sample.
They are useful when studies require quantitative assessment of pathogen detection, host gene expression, cytokine responses, or immune biomarkers. A common reference allows results from different samples or experiments to be compared on a consistent basis. This is particularly relevant when researchers examine transcriptional changes associated with infection or immune activation and need confidence that observed differences reflect biology.
Using RNA materials with defined identity, concentration, and assessed quality gives separate experiments a shared measurement reference. Consistent dilutions further reduce variation introduced during preparation. As a result, researchers can compare assay performance and RNA measurements more reliably across experiments or laboratories, helping distinguish genuine biological differences from inconsistencies in measurement or reference material handling.
