Title Original_Prox1_1
Sample type SRA
Source name small intestine
Organism Mus musculus

Extracted molecule total RNA
Extraction protocol epithelial cell preparation from proximal jejunum of mice
Cellular suspensions were loaded on a GemCode Single Cell Instrument (10x Genomics, Pleasanton, CA) to generate single-cell GEMs for the "Original Prox1_1" and "Orginal_Prox1_2" samples, which are two technical replicates. Single-cell RNA-Seq libraries were prepared using GemCode Single Cell 3’ Gel Bead and Library Kit (now sold as P/N 120230, 120231, 120232, 10x Genomics) following the protocols outlined in Zheng et. al. 2017. The remainder of the libraries were made using the Chromium Single Cell Instrument to generate single-cell GEMs using the Chromium Single Cell 3' Gel Bead and Library Kit from 10x Genomics (#120235, 120234, 120236, 120262).
For the "Original_Prox1_1" and "Original_Prox1_2" samples, the sequencing libraries were loaded at 2.1 pM on an Illumina NextSeq500 with 2 × 75 paired-end kits using the following read length: 98 bp Read1, 14 bp I7 Index, 8 bp I5 Index and 5 bp Read2. Note that these libraries were generated before the official launch of GemCode Single Cell 3’ Gel Bead and Library Kit. Thus 5bp UMI was used (the official GemCode Single Cell 3’ Gel Bead contains 10 bp UMI). For the remainder of the samples, the sequencing libraries were loaded at 2.1 pM on an Illumina Hiseq4000 with 2 × 75 paired-end kits using the following read length: 26 bp Read1, 8 bp I7 Index and 98 bp Read2.
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina NextSeq 500
Description GemCode
Data processing The Cell Ranger Single Cell Software Suite 1.3 was used to perform sample demultiplexing, barcode processing, and single cell 3’ gene counting ( For the old Prox1+ samples, UMI=5 was used for the analysis.
