When you upload your flow cytometry files (FCS files), Cytobank scans them to see what names you gave each Channel when you collected the data.  All the files with the same set of channels are placed onto a Staining Panel.  

For example, if you collected 10 files and for 5 of them you labeled the channels CD3-FITC, CD4-PE, CD8-PerCP, and p-STAT5-Ax647 and for the other 5 you labeled the channels CD3-FITC, CD4-PE, CD8-PerCP, and p-ERK-Ax647, Cytobank would find two Staining Panels and put the 5 files onto each of them.  Cytobank will also automatically import the names of the channels you typed in.
