Description

The BD™ CBA Total Stat1 Flex Set is a bead-based immunoassay capable of measuring human, mouse or rat signal transducer and activator of transcription 1 (Stat1). Human reactivity was determined by testing cell lysates with the BD CBA Total Stat1 Flex Set. Reactivity with mouse and rat samples was determined by western blot for each of the antibodies used in the BD CBA Total Stat1 Flex Set. The biology and function of Stat1 has been previously reviewed. For more information on bead-based immunoassays, refer to the product insert for the BD CBA Cell Signaling Master Buffer Kit (Cat. No. 560005 or 560006).

Preparation And Storage

This BD™ CBA Flex Set contains one vial of each component listed above. All components of this flex set have been formulated to a 50x concentration to ensure product performance when multiplexed. Store at 4°C. Protect Capture Beads and the PE Detection Reagent from prolonged exposure to light.

The Total Stat1 Standard provided in this Flex Set is lyophilized and the standard sphere should be transferred to a 1.5 mL microfuge tube for reconstitution. Reconstitute the standard with 0.1 mL Assay Diluent from the BD CBA Cell Signaling Master Buffer Kit (Cat. No. 560005/560006), warm to 37 °C and vortex prior to use. After reconstitution, the standard concentration is 50,000 Units/mL and is stable for 3 months when stored at 4 °C. When using reconstituted standard, warm to 37 °C and vortex to mix thoroughly before use.

Recommended Assay Procedures

The BD CBA Total Stat1 Flex Set must be used in conjunction with a BD CBA Cell Signaling Master Buffer Kit (Cat. No. 560005, 100 tests, or 560006, 500 tests) and a flow cytometer. Detailed instructions on the use of this product can be found in the manual for the BD CBA Cell Signaling Master Buffer Kit. When following the directions in the Master Buffer Kit, the top standard point for the BD CBA Total Stat1 Flex Set will be 1,000 Units/mL. An example standard curve is shown in Figure 1.

The BD CBA Total Stat1 Flex Set should not be used in the same assay well with any non-BD CBA Cell Signaling Flex Set reagents (such as BD CBA Human or Mouse Soluble Protein Flex Sets) nor with any BD CBA Phospho-specific Cell Signaling Flex Set reagents.  For an updated assay compatibility chart for the BD CBA Cell Signaling Flex Sets, please refer to the BD CBA Flex Set System homepage at http://www.bdbiosciences.com/cbasetup.

Performance

Limit of Detection: The theoretical limit of detection is 0.98 Units/mL and was determined by evaluating the estimated result of the average MFI of the negative control (0 Units/mL, n=30) + 2 standard deviations.
