Nexcelom's team of Field Applications Scientists, R&D Specialists and Product Managers are in frequent contact with researchers in the field, developing new experiments that can be performed on the Celigo image cytometer.
We have taken this information and generated three unique types of documents:
Celigo Assays: In these red-colored documents, we summarize in 1-2 pages a basic overview of how certain assays would be performed on the Celigo. We include any stains needed, the imaging channels used on the Celigo, and a truncated review of methods and results generated from the assay. These are quick snapshots, providing proof of concept of specific assays that have been performed successfully on the Celigo.
Celigo Demonstration Experiments: In these green-colored documents, we outline in detail specific experiments that have been conducted on the Celigo. In these demonstration experiments we highlight the plate set up, assay protocol, detailed results generated by the Celigo, as well as a conclusion and summary of the outcome of the experiment.
Celigo Application Protocols: In these blue-colored documents, we provide a step-by-step guide on how to prepare, perform and analyze specific assays using the Celigo image cytometer. These are designed to comprehensively walk users through every step of the experiment: from prep to data analysis.
Our team continues to create new Celigo Assays, Demonstration Experiments and Applications Protocols documents. For the most current materials, please visit our website or reach out to your local area manager or applications scientist. The chart on the next page depicts the Celigo Assays, Celigo Demo Experiments and Celigo Applications Protocols that currently exist for different applications and assays. If you are interested in viewing any of the Celigo Assays or Celigo Demo Experiment documents, they are individually readily available on www.nexcelom.com for download. Simply type the name of the assay into the search bar on the homepage. We have also created an eBook version of all our Celigo Assays and all our Celigo Application Protocols

Goal
MeasurePBMC-mediatedcytotoxicityusingcalceinAM-stainedK562Targetcellsforadurationof4hours.
Protocol
Cellpreparation
12. K562cellswereobtainedfromATCCandculturedinRPMI1640media13. TwodonorswereobtainedfrombuffycoatusingFicollprocess14. TheK562Targetcellswerestainedwith5µMofcalceinAM(Nexcelom,Cat#CS1-0119)for30minand
thenwashed3timeswithRPMImedia15. Thecellwerethenseededintoa96-wellplateat10,000cells/well16. Next,thePBMCswereadded,followingtheE:Tratiosontheplatemapbelow17. Finally,IL2wasaddedtohalfofthewellstoactivateNKcells
