Bead-based Multiplexing Assay for PRA Screening

As the leader in HLA antibody screening, One Lambda offers the largest portfolio of assays for low- to high-resolution detection. Our selection of reagents for the LABScreen line of products are powered by Luminex® xMAP® technology—a microbead platform used to deliver multiplex antibody assays in high-PRA patients. These single antigen-bead based assays allow for precise determination of antibody profiles against HLA, MICA or HNA.

LABScreen assays produce trusted results, with consistency and high sensitivity, and are considered to be the gold standard in HLA antibody detection.

assay for PRA Screening

  • Similar workflow for all LABScreen products
  • All LABScreen assays can be batched together in the same run
  • Test can be completed in approximately 2.5 hours

How does LABScreen Work

LABScreen products use a panel of color-coded microbeads, coated with purified HLA antigens. Up to 100 different beads can be combined in one suspension in a single test. The serum is incubated with LABScreen beads. Any HLA antibodies in the serum bind to the antigens and are labeled with PE-conjugated goat anti-human IgG. The LABScan™ 100 or LABScan3D™ systems detect fluorescent emission of PE from each bead, allowing nearly real-time data acquisition.
