Technology Methods

Multiplexing  

Simple Western provides high-quality, size-based data in just three hours, with only one hour of hands-on time. Multiplexing allows you to analyze two targets in a single capillary, doubling the data points per sample and maximizing the value of your precious samples while saving time. With fluorescence and chemiluminescence channels, Jess and Leo enable powerful multiplexing for efficient and insightful immunoassays.

RePlex- Achieving More Quantitative Data From Every Sample 

RePlex™ assay enables two sequential immunoassays (IA) or an IA + total protein assay (TPA) within the same capillary, maximizing data output from each sample load and providing deeper biological insight without additional sample consumption.  

With the RePlex feature, Simple Western offers flexible multiplexing options that allow you to do multi-target detection and protein normalization in the same capillary.

Extracellular vesicle protein analysis 

Simple Western technology is increasingly being applied to extracellular vesicle (EV) protein analysis, providing a powerful tool to characterize the protein cargo of these nanosized particles. EVs, including exosomes and microvesicles, play critical roles in intercellular communication and are often studied for their potential as biomarkers or therapeutic agents. With its automated, highly sensitive, and quantitative approach, Simple Western allows researchers to analyze EV protein expression patterns efficiently and reproducibly. Simple Western is particularly valuable in overcoming challenges related to the heterogeneity and low protein concentrations of EV samples, enabling deeper insights into EV biology and their applications in diagnostics and therapeutics.
