Thermo Fisher Scientific MDC Human ProcartaPlex Simplex Kit

Invitrogen™ MDC Human ProcartaPlex™ Simplex Kit

The Human MDC Simplex ProcartaPlex Kit measures MDC protein and is designed to be combinable with other Simplex kits, allowing creation of custom multiplex panels utilizing Luminex xMAP technology for protein detection and quantitation. When combining multiple Simplex kits, only one buffer kit (sold separately) is required per assay plate regardless of plex size.

About ProcartaPlex Assays for the Luminex Platform

ProcartaPlex immunoassays are based on the principles of a sandwich ELISA, using two highly specific antibodies binding to different epitopes of one protein to quantitate multiple protein targets simultaneously using a Luminex instrument. These multiplex assays require as little as 25 μL of plasma or serum, or 50 μL of cell culture supernatant, and provide analyzed results within four hours.

• More results per sample — measure multiple protein targets simultaneously in a single 25–50 μL sample
• Well-established Luminex technology — highly referenced multiplexing platform for protein detection and quantitation

ProcartaPlex assays utilize Luminex xMAP (multianalyte profiling) technology for simultaneous detection and quantitation of up to 80 protein targets in a single 25–50 μL sample from plasma, serum, cell culture supernatants, and other bodily fluids.

The Luminex beads in the ProcartaPlex assay are internally dyed with precise proportions of red and infrared fluorophores to create spectrally unique signatures identifiable by Luminex detection systems (e.g., Luminex 200, FLEXMAP 3D, MAGPIX). Similar to a sandwich ELISA, matched antibody pairs identify the target protein. Each bead is labeled with antibodies specific for a single target protein, and bound proteins are detected with biotinylated antibodies and streptavidin–R-phycoerythrin (RPE).

Unlike ELISA, the capture antibody in ProcartaPlex assays is conjugated to a bead and not adsorbed to a microplate well, allowing reagents to remain free-floating. Detection instruments such as the Luminex 200 use two lasers—one to distinguish bead signatures and another to quantify RPE fluorescence, proportional to protein concentration. ProcartaPlex assays enable profiling of more targets using less sample and time compared to traditional ELISA.

ProcartaPlex multiplex panels are available for multiple species (human, mouse, rat, nonhuman primate, porcine, canine).
