CST, 32722S, SignalStar™ Fluorescence Removal Kit

Buffer Kit for studying in the research area. Product Usage Information The SignalStar™ Fluorescence Removal Kit is intended for use following the SignalStar ® Multiplex IHC Assay Manual protocol or the SignalStar ® Multiplex IHC Assay for Use on BOND RX Fully Automated Research Stainer by Leica Biosystems protocol. Continue to follow all guidance and recommendations from the original protocol when using the SignalStar™ Fluorescence Removal Kit. For the SignalStar ® Multiplex IHC Assay Manual protocol: 1. After the second round of image acquisition, soak slides in dH 2 O for >30 min to gently remove coverslip.2. Combine reagents to create the SignalStar Fluorescence Removal Solution: a. For 5 slides: 75 µL 10X dsDNase Buffer, 7.5 µL dsDNase, and 667.5 µL Nuclease-free Water # 12931 . b. For 10 slides: 150 µL 10X dsDNase Buffer, 15 µL dsDNase, and 1,335 µL Nuclease-free Water # 12931 . 3. Cover with parafilm and vortex for 10 sec. Store all SignalStar kit components on ice when preparing solutions. SignalStar solutions should be used promptly once all reagents have been combined for the run. 4. Incubate slides in 150 µL of SignalStar Fluorescence Removal Solution for 2 hr at 37°C. (Use of a covered humidity chamber is highly recommended to prevent evaporation.) 5. Immerse slides in dH 2 O for 30 sec. 6. Complete any additional staining and imaging steps following your manufacturer's protocol. For the SignalStar ® Multiplex IHC Assay for Use on BOND RX Fully Automated Research Stainer by Leica Biosystems protocol: 1. In the BOND RX software by Leica Biosystems, create a copy of the "CST SignalStar Imaging Round 2" protocol. 2. Change the name of the copy to "CST SignalStar Imaging Round 3" with the abbreviated name "CST Rd3." 3. Select "Show wash steps." 4. Delete Steps 8-63, saving only steps 1-7 for fluorescence removal. 5. Add steps required for any additional staining following your manufacturer's protocol. 6. Select "CST SignalStar" as the preferred Detection System (Note: Additional staining steps may require further selection of other Detection Systems. Please contact Leica Biosystems for assistance.) 7. Select "Create Protocol." 8. Click the Save button and then the Yes button to acknowledge the caution message. 9. After the second round of image acquisition, soak slides in dH 2 O for >30 min to gently remove coverslip. 10. Combine reagents to create the SignalStar Fluorescence Removal Solution: a. For 5 slides: 185 µL 10X dsDNase Buffer, 18.5 µL dsDNase, and 1,646.5 µL Nuclease-free Water # 12931 in 1 BOND Titration Insert. b. For 10 slides: 335 µL 10X dsDNase Buffer, 33.5 µl dsDNase, and 2,981.5 µL Nuclease-free Water # 12931 in 1 BOND Titration Insert. 11. Cover with parafilm and vortex for 10 sec. Store all SignalStar kit components on ice when preparing solutions. SignalStar solutions should be used promptly once all reagents have been combined for the run. 12. In the BOND RX software, create a study and add slides. 13. When "adding slides," use the selections below for Tissue Preparation on BOND: a. Slide preparation: -- (no value/not required) b. Dispense Volume: 150 µL c. HIER: -- (no value/not required) 14. Select "CST SignalStar Imaging Round 3," ensuring that Slide preparation is selected as "--" and HIER is selected as "--." 15. Print labels, add labels to slides, and place slides onto the slide tray. 16. Place 2-3 drops of dH 2 O onto each slide before adding BOND covertiles. 17. Start the BOND RX run. Storage All components in this kit are stable for at least 12 months when stored at the recommended temperature.
