BD™ Cytometric Bead Array (CBA) Human MCP-1 Flex Set

Figure 1. Example BD CBA Human MCP-1 Flex Set standard curve. Data acquired on a BD FACSArray bioanalyzer and analyzed using FCAP Array Software.

Reproducibility: The inter-assay and intra-assay reproducibility were determined for the BD CBA Human MCP-1 Flex Set by evaluating ten replicates of three different sample levels (inter-assay) and two replicates of three different sample levels from four separate experiments (intra-assay) respectively.

Recovery: Cell culture supernatant, serum, or EDTA-treated plasma were spiked with three different levels of protein. The spiked samples were assayed and the results were compared with expected values. Serum and plasma samples were diluted 1:4 before the protein was spiked into each. Serum is a pool of 800 - 1000 donors and the plasma was pooled from at least 20 donors.

Linearity: Cell culture supernatant, 1:4 diluted serum, or 1:4 diluted EDTA-treated plasma were spiked with protein and serially diluted. The diluted samples were assayed and the results were compared with the original spiked sample.
