    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.
    Human TNF Flex Set
    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.

    Reproducibility: The inter-assay and intra-assay reproducibility were determined for the BD CBA Human TNF 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.

    Description

    The BD™ CBA Human TNF Flex Set is a bead-based immunoassay capable of measuring human tumor necrosis factor (TNF), formerly known as tumor necrosis factor-α, in serum, plasma, and cell culture supernatant samples. Human and non-human primate reactivity was determined by testing samples with the BD CBA Human TNF Flex Set. The biology and function of TNF has been extensively reviewed in the literature. For more information on bead-based immunoassays, refer to the product insert for the BD CBA Human Soluble Protein Master Buffer Kit (Cat. No. 558264 or 558265).

    Preparation And Storage

    This BD™ CBA Flex Set contains one vial each of Capture Bead and PE Detection Reagent and two vials of Standard. The Capture Bead and PE Detection Reagent components of this flex set have been formulated to a 50x concentration to ensure product performance when multiplexed. The Standard component is lyophilized and should be transferred to a 15 ml polypropylene tube for reconstitution. When reconstituted in 4.0 ml Assay Diluent, the standard has a protein concentration of 2,500 pg/ml. Discard unused reconstituted standard, do not store or reuse. Store lyophilized standard and other components at 4°C. Protect PE Detection Reagent from prolonged exposure to light.

    Recommended Assay Procedures

    The BD CBA Human TNF Flex Set must be used in conjunction with a BD CBA Human Soluble Protein Master Buffer Kit (Cat. No. 558264, 100 tests, or 558265, 500 tests), a flow cytometer, and the FCAP Array™ Software (Cat. No. 641488). Detailed instructions on the use of this product can be found in the manual for the BD CBA Human Soluble Protein Master Buffer Kit. When following the directions in the Master Buffer Kit, the top standard point for the BD CBA Human TNF Flex Set will be 2,500 pg/ml. An example standard curve is shown in Figure 1.

    The BD CBA Human TNF Flex Set cannot be used in the same assay well with the following BD CBA Human Soluble Protein Flex Set reagents:

    Flex Set                                         Bead Position                        Catalog Number

    BD CBA Human TNF Flex Set                C4                                     560112

    The BD CBA Human TNF Flex Set should not be used in the same assay well with any non-BD CBA Human Soluble Protein Flex Set reagents (such as BD CBA Mouse Soluble Protein or Cell Signaling Flex Sets). For an updated assay compatibility chart for the BD CBA Human Soluble Protein Flex Sets, please refer to the BD CBA Flex Set System homepage at http://www.bdbiosciences.com/flexset.

    Performance

    Limit of Detection: The theoretical limit of detection is 0.7 pg/ml and was determined by evaluating the estimated result of the average MFI of the negative control (0 pg/ml, n=30) + 2 standard deviations.
