Spatial transcriptome analysis (Slide-seq2) of mouse main olfactory bulb

The goal of spatial transcriptome analysis is to profile the glomeruli position representing different olfactory receptors. 20 OB sections were obtained with equal spacing (130 μm) along the anterior-posterior axis. In total, two sets of 20 slides were obtained from different animals. All of the Slide-seqV2 procedures were performed as previously described Olfactory epithelial single cell suspensions made from 3 male and 3 female adult mice. Single-cell sequencing libraries were prepared using Chromium Single Cell 3’ Reagent Kit V3 (10X Genomics) according to the manufacturer’s guidelines. Libraries were sequenced using 150 cycles of paired end reads on Illumina Hiseq4000 and Novaseq6000 instruments (Novogene)
