Human CXCL13/BLC/BCA-1 Magnetic Luminex® Performance Assay Summary
| Panel | Luminex Performance Human Biomarker Panel A |
| Assay Type | Magnetic bead-based multiplex assay for the Luminex® platform |
| Format | 1 x 96-well microplate and Magnetic antibody-coated beads |
| Species | Human |
| Analytes Detected | Please see analyte list in assay customization tool below. |
| Performance Validation | Our Luminex High Performance Assays undergo our most extensive validation testing. All Luminex High Performance Assay Panels are validated for use with serum and plasma samples. Some High Performance Assays are additionally validated for cell culture supernatants, milk, saliva, or urine, as indicated on the individual product data sheets. Luminex High Performance Assays are tested for sensitivity (three-quarters the low standard), intra-assay precision, inter-assay precision, and to ensure assay linearity for validated sample types. Recovery values for individual samples in validated sample types are also tested. Validation data for each analyte can be found in the product datasheet. |

Assays for the Luminex platform are offered as High Performance Assays or Assays. The Luminex High Performance Assays are fully validated panels with a focused selection of analytes. They are available in We Mix, You Mix, and Predetermined formats. The Luminex Assays allows for the maximum number of analytes in a multiplex and is supplied as a premixed kit. View a table comparing the features and benefits of these bead-based multiplex assays.
Magnetic Luminex High Performance Assays are designed for use with the Luminex MAGPIX CCD Imager. Alternatively, kits can be used with the Luminex 100/200™ or Bio-Rad® Bio-Plex®, dual laser, flow-based sorting and detection platforms.
Analyte-specific antibodies are pre-coated onto color-coded microparticles. Microparticles, standards, and samples are pipetted into wells and the immobilized antibodies bind the analytes of interest. After washing away any unbound substances, a biotinylated antibody cocktail specific to the analytes of interest is added to each well. Following a wash to remove any unbound biotinylated antibody, Streptavidin-Phycoerythrin conjugate (Streptavidin-PE), which binds to the biotinylated detection antibodies, is added to each well. A final wash removes unbound Streptavidin-PE and the microparticles are resuspended in buffer and read using the Luminex or Bio-Plex analyzer. One laser is bead-specific and determines which analyte is being detected. A magnet in the analyzer captures and holds the superparaMagnetic microparticles in a monolayer. Two spectrally distinct Light Emitting Diodes (LEDs) illuminate the beads. One LED identifies the analyte that is being detected and the second LED determines the magnitude of the PE-derived signal, which is in direct proportion to the amount of analyte bound. Each well is imaged with a CCD camera. Kits can also be used with Luminex 100/200 or a Bio-Rad Bio-Plex dual laser, flow-based systems.

Background: CXCL13/BLC/BCA-1
CXCL13/BLC/BCA-1 is a constitutively expressed chemokine that plays an important role in B and T cell homing. It is expressed by salivary gland epithelium, dendritic cells, osteoclasts, and peritoneal macrophages. It can form homodimers or heterodimers with FGF basic, and it signals through CXCR3 or CXCR5. CXCL13 induces the migration of naïve B cells and a subset of memory T cells to lymphoid tissue. It also promotes B1 cell migration into the omentum and peritoneum. In the fetus, CXCL13 attracts CD4+ CD3- IL-7 R alpha+ hematopoietic cells to sites of future Peyer’s patch development.
