H2: How Does Nanostring Technologies Work?
Nanostring’s technology is based on its unique digital molecular barcoding system, which involves the use of color-coded molecular tags. These tags are designed to hybridize directly with target nucleic acids or proteins, allowing for a precise counting process that is robust against variations often seen in traditional PCR or next-generation sequencing (NGS) methods.
H3: Step-by-Step Process of the nCounter® Analysis System
- Sample Preparation: Biological samples, such as RNA, DNA, or protein, are extracted and prepared for analysis.
- Hybridization: Target-specific probes hybridize to their corresponding molecules in the sample.
- Barcode Labeling: Each molecule is tagged with a unique color-coded barcode.
- Digital Counting: A digital analyzer scans the samples and counts the barcodes, providing quantitative data on the gene or protein expression levels.
