MtoZ Biolabs has launched the electrochemiluminescence (ECL) assay service which enables precise and quantitative analysis of the expression levels of specific target proteins. This service is suitable for targeted proteomics research and is widely applied in biomarker validation and protein expression analysis, providing strong support for obtaining reliable quantitative data on target proteins.
What Is Electrochemiluminescence (ECL)?
Electrochemiluminescence (ECL) is a highly sensitive detection technology that combines electrochemical reactions with chemiluminescent signals. By triggering labeled luminophores on the electrode surface to generate controlled light signals, ECL enables accurate quantitative analysis of target proteins. Its core principle is to electrochemically excite luminescent probes and correlate the emitted light intensity with the abundance of target molecules, offering advantages such as low background noise and a wide dynamic range. ECL is particularly important in targeted protein detection, as it allows stable and accurate measurement of trace protein changes and provides reliable support for highly specific biological analyses.

Q4: How should I prepare my samples?
A4: To ensure optimal detection performance, it is recommended to prepare samples as follows:
(1) Sample Purity: Samples should remain clean, free of particulate matter, and without significant matrix interference.
(2) Sample Storage: Store at 4℃ for short-term use; for long-term storage, place at -80℃ and avoid repeated freeze-thaw cycles.
(3) Sample Transport: Use sealed containers and maintain low temperatures during transport to prevent degradation.
(4) Additional Information: Provide sample type, processing steps, concentration, and experimental background to enable selection of the most appropriate detection scheme.
