Description
The Mouse Th1/Th2 Cytokine Standards contain a mixture of individually lyophilized recombinant proteins made up of recombinant mouse Interleukin (IL)-2, IL-4, IL-5, Interferon-γ (IFN-γ), and Tumor Necrosis Factor (TNF). The reconstituted Mouse Th1/Th2 Cytokine Standards are designed for use as a standard control with the BD™ Cytometric Bead Array (CBA) Mouse Th1/Th2 Cytokine Kit (Cat. No. 551287). Please refer to the manual included with the BD™ Cytometric Bead Array (CBA) Mouse Th1/Th2 Cytokine Kit for further information.
Preparation And Storage
Lyospheres from 1 vial of the Mouse Th1/Th2 Cytokine Standards, when reconstituted in 2.0 mL Assay Diluent, approximates the CBA activity of mouse IL-2, IL-4, IL-5, Interferon-γ (IFN-γ), and Tumor Necrosis Factor (TNF) at a concentration of 5000 pg/mL. Following reconstitution, maintain the Mouse Th1/Th2 Cytokine Standards at 4°C and use within 12 hours. Any unused reconstituted standard must be discarded after this period (do not store or reuse).
Recommended Assay Procedures
The Mouse Th1/Th2 Cytokine Standards have been tested with the BD™ Cytometric Bead Array (CBA) Mouse Th1/Th2 Cytokine Kit (Cat. No. 551287) to assure function as a standard in the CBA assay. Investigators are encouraged to refer to the manual for the BD™ Cytometric Bead Array (CBA) Mouse Th1/Th2 Cytokine Kit (Cat. No. 551287). The Mouse Th1/Th2 Cytokine Standards are lyophilized and should be reconstituted and serially diluted before mixing with CBA capture beads and PE detection reagents. An abbreviated instruction has been provided below (Preparation of Mouse Th1/Th2 Cytokine Standards). The Mouse Th1/Th2 Cytokine Standards should be reconstituted using Assay Diluent, which is provided with the BD™ Cytometric Bead Array (CBA) Mouse Th1/Th2 Cytokine Kit (Cat. No. 551287), or it may be purchased separately (Cat. No. 560104).
Preparation of Mouse Th1/Th2 Cytokine Standards for use with the BD™ CBA Mouse Th1/Th2 Cytokine Kit (Cat. No. 551287)
1. Open one vial of the lyophilized Mouse Th1/Th2 Cytokine Standards. Transfer all lyospheres to a polypropylene tube. Label the tube "Top Standard".
2. Reconstitute the standard with 2.0 mL of Assay Diluent. Allow the reconstituted standard to equilibrate for at least 15 minutes before making dilutions. Mix the reconstituted protein by pipette only. Do not vortex or mix vigorously.
3. Label additional 12 x 75 mm tubes and arrange them in the following order: Top Standard, 1:2, 1:4, 1:8, 1:16, 1:32, 1:64, 1:128, and 1:256.
4. Add 300 µl of Assay Diluent to each of the dilution tubes.
5. Perform a serial dilution by transferring 300 µl from the Top Standard to the 1:2 dilution tube and mix thoroughly. Do not vortex, mix by pipet only. Continue making serial dilutions by transferring 300 µl from the 1:2 tube to the 1:4 tube and so on to the 1:256 tube and mix thoroughly. Prepare one tube containing only Assay Diluent to serve as the 0 pg/mL negative control.
