nCounter Analysis System: A Deep Dive

The nCounter Analysis System stands out as a pivotal technology developed by NanoString, offering a unique approach to gene expression analysis and beyond. This system is designed for highly multiplexed measurement of RNA, DNA, and protein, providing researchers with unparalleled sensitivity and specificity. Let's explore the nCounter system in detail.

How nCounter Works

The nCounter system operates on the principle of direct digital detection of target molecules. Unlike traditional methods that rely on amplification, the nCounter system uses molecular barcodes to count individual molecules. The process involves the following steps:

Probe Design: The first step is to design probes that are specific to the target RNA or DNA sequences. Each probe consists of two components: a capture probe and a reporter probe. The capture probe hybridizes to the target molecule, while the reporter probe carries a unique molecular barcode.
Hybridization: The probes are hybridized to the sample, allowing them to bind to their target sequences. The hybridization process is highly specific, ensuring that only the intended targets are detected.
Target Capture: After hybridization, the complexes are captured using a streptavidin-coated surface. This step removes unbound probes and other contaminants, ensuring that only the target molecules are analyzed.
Digital Counting: The captured complexes are then aligned and counted using a digital analyzer. The analyzer detects the molecular barcodes on the reporter probes, providing a quantitative measure of the abundance of each target molecule.
