Single Molecule Protein Detection - Simoa Testing Services

Product Description

• Ideal for low abundance proteins, low volume samples 
• Compatible with serum, plasma, CSF, other complex matrices
• Multiplexing available for up to 4 analytes
• Ship your samples, and we'll do the rest

Single molecule array (Simoa^®) testing is a powerful new technique that is orders of magnitude more sensitive than standard sandwich based immunoassay techniques.

Simoa requires a dedicated detector. For researchers who don't have accesss to such a device, we offer the Simoa Testing Service where samples can be shipped to us, and RayBiotech will perform the assay and create a data report. Please contact us to discuss your project and get a quote.

A minimum of 10 samples is required to order this service. Multiplexing is available for up to 4 analytes.

How it Works

Simoa, which stands for single molecule array, is a bead-based sandwich immunoassay. The antibody-coated beads, the sample, and the fluorescently conjugated detection antibody are mixed together to form immunocomplexes. This mixture is then applied to a cartridge with over 200,000 microwells, with each microwell only being able to hold one bead. This enables a precise fluorescent readout in the femtomolar range even when only a single molecule of the target analyte is bound to the bead.
