Click-iT™ Plus OPP Alexa Fluor™ 647 Protein Synthesis Assay Kit - FAQs

Q: Can the Click-iT Plus OPP Alexa Fluor 647 Protein Synthesis Assay Kit (Cat. No. C10458) be used for detection in flow cytometry?

The Click-iT OPP Assay Kits (Cat no. C10456, C10457 and C10458) can be used with any application that detects whole cells; therefore, the assay can be adapted for flow cytometry. You can follow the imaging protocol for labelling in the user guide. Briefly, you would need to spin the cells down (<2,000 rpm) to wash instead of covering the cells with the Click-iT Reaction Rinse Buffer as mentioned in step 5.6 on page 7 of the user guide. The picolyl azide dye concentration used in the click reaction has been optimized for imaging, which is less sensitive than flow. We recommend reducing this volume from 1/5th up to 1/10th the protocol volume for flow detection and making up the difference with 1X Reaction Buffer while keeping the volumes of the click reagents the same as in the protocol.

I will be performing a cell proliferation assay using Click-iT EdU kit. At what point can I stop overnight, or do I have to perform all the steps continuously?

One may store the sample after fixation overnight in PBS at 4^oC. For longer storage (<1 week) , store in buffer with 1-2% formaldehyde or in formalin to limit microbial growth. If you use sodium azide as a microbial inhibitor, it must be completely removed prior to the Click-iT reaction.
