Fig. 6: Biological utility of AutoSpill.
Downstream analyses of data compensated by either the traditional compensation algorithm or AutoSpill. a Plots were prepared and compensated using FlowJo v.10.6, using either the default traditional algorithm or uploading the spillover matrix generated by AutoSpill. Representative flow cytometry plots illustrating errors corrected by AutoSpill (MM2 dataset). b–e All plots were prepared from the same FCS files and compensated using FlowJo v.10.7, using either the traditional algorithm or the AutoSpill option. b Representative flow cytometry plots illustrating errors corrected by the AutoSpill option in FlowJo v10.7, c including hierarchical gating for CD4+CD8+CD25+ lymphocytes (MM3 dataset). d The CD4+CD25+ population gated in b was backgated to identify the source of population loss in the traditional algorithm (MM3 dataset). e MHCII expression on known negative cells (CD4 T cells), known positive cells (CD11b+ splenocytes), and microglia (MM4 dataset). f Percent positive was thresholded using CD4 T cells as the negative. MHCII knockout microglia we`re used as a true negative staining control. g Foxp3GFP expression on known bimodal cells (CD4+ splenocytes) and CD11b+ macrophages (MM5 dataset). h The positive population was thresholded using the negative CD4 T cell peak. Wildtype mice, without the GFP transgene, were used as a true negative staining control. Pseudo-color represents cellular density. For gating strategy see Fig. S3. Traditional and AutoSpill spillover matrices are provided on Mendeley data: [http://dx.doi.org/10.17632/mtdww9hd3m.1]. MM2, MM3, MM4, MM5 Raw datasets are available at FlowRepository with IDs FR-FCM-Z2SW (MM2) [https://flowrepository.org/id/FR-FCM-Z2SW], FR-FCM-Z2SJ (MM3) [https://flowrepository.org/id/FR-FCM-Z2SJ], FR-FR-FCM-Z2SK (MM4) [https://flowrepository.org/id/FR-FCM-Z2SK], and FR-FCM-Z2SL (MM5) [https://flowrepository.org/id/FR-FCM-Z2SL].
