Multiplexing is a technology that allows for the simultaneous detection of multiple analytes in a single sample. This is accomplished by using different colors of fluorescent beads, each of which is conjugated to a specific antibody. The beads are then mixed with the sample and incubated. After incubation, the beads are washed to remove unbound material, and then analyzed on a flow cytometer.

Multiplexing offers many benefits over traditional ELISA assays, including increased throughput, lower costs, and the ability to measure multiple analytes in a single sample. Additionally, multiplexing can be used to measure both antibodies and antigens, making it a versatile tool for research and diagnostics.
One downside of multiplexing is that it can sometimes be difficult to interpret the data, as the different colors of beads can produce a lot of noise. However, newer flow cytometers are equipped with algorithms that can help to filter out this noise and provide more accurate data.
Multiplexing ELISA can be used to detect multiple proteins, cytokines, or other analytes in a single sample, which can save time and money. There are two main types of multiplexing ELISA: sandwich and competitive. Sandwich ELISA is the most common and it detects analytes by using two antibodies that bind to different epitopes on the target analyte.
Competitive ELISA detects analytes by using a single antibody that binds to an epitope on the target analyte. Multiplexing ELISA has many applications, such as detecting multiple protein biomarkers in a single sample, measuring cytokine levels in blood, and more.
