Thermo Fisher Scientific Elafin Human ProcartaPlex Simplex Kit

Invitrogen™ Elafin Human ProcartaPlex™ Simplex Kit

The Human Elafin Simplex ProcartaPlex Kit measures elafin protein and is designed to be combinable with other Simplex kits so that you can create your own multiplex panel utilizing Luminex xMAP technology for protein detection and quantitation. When combining multiple Simplex kits (i.e., when not using a pre-configured Multiplex Panel), only one buffer kit (sold separately) is needed 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. ProcartaPlex multiplex assays require as little as 25 μL of plasma or serum, or 50 μL of cell culture supernatant, and just four hours to obtain analyzed results.

주요 특징

• 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 the simultaneous detection and quantitation of up to 80 protein targets in a single small-volume 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 that can be identified by Luminex xMAP detection systems (e.g., Luminex 200, FLEXMAP 3D, and MAGPIX). Similar to a sandwich ELISA, the ProcartaPlex assay uses matched antibody pairs to identify the protein of interest. In a multiplexed assay, each spectrally unique bead is labeled with antibodies specific for a single target protein, and bound proteins are identified with biotinylated antibodies and streptavidin–R-phycoerythrin (RPE). The conjugation of protein-specific antibodies to a distinct bead allows for analysis of multiple targets in a single well.

The most significant difference between a ProcartaPlex assay and ELISA is that the capture antibody in the ProcartaPlex assay is conjugated to a bead and not adsorbed to the microplate well, so the reagents are free-floating in solution. For detection, the Luminex instrument (e.g., Luminex 200) uses two lasers—one to distinguish the spectral signature of each bead and another to quantify the RPE fluorescence, which is proportional to the amount of protein present in the sample. ProcartaPlex multiplex assays can profile more target proteins using significantly less sample in the same time as a traditional sandwich ELISA.

ProcartaPlex multiplex panels are available in multiple formats across six species (human, mouse, rat, nonhuman primate, porcine, and canine).
