Channel catfish, Ictalurus punctatus, are the primary cultured species of the catfish industry. Significant losses in production are attributed to bacterial diseases which are challenging to control and new interventions need to be developed. To gain insight into the in situ catfish immune system, we used single-nuclei RNAseq. We produced two single-nuclei atlases from three individual catfish using flow cytometry sorted IgM+ splenic cells. Libraries were prepared using the 10X Genomics system and sequenced on an Illumina sequencer. The reads were aligned to the reference genome (Ip Coco_2.0) using Cell Ranger (v8.0.0). Overall design: Spleen samples from three adult catfish were collected and sorted for IgM+ cells to generate a channel catfish IgM+ cell transcriptome atlas.
