ATCC nist stool matrix
Stool samples collected from omnivorous donors and processed into a single standardized matrix by <t>NIST</t> was spiked with ATCC CoV-2 RNA or BCoV vaccine. Spiked stool was preserved in the OMNIgene-GUT Kit (OG), Zymo DNA/RNA shield buffer (ZY), and PBS (as indicated in the tab on the top). RNA was extracted from these samples by two independent users, each in duplicate, using the MagMAX Viral/Pathogen Kit (MM; green), QIAamp Viral RNA Mini Kit (QA; orange), or Zymo Quick-RNA Viral Kit (ZY; purple) as indicated on the x -axis. RNA was assayed using ddPCR. a Absolute concentration of SARS-CoV-2 RNA assayed by ddPCR targeting the N1 gene is plotted on the y -axis. NIST stool matrix was spiked with 10 <t>3</t> <t>(triangle)</t> or 10 4 (square) copies of ATCC synthetic SARS-CoV-2 RNA. b Absolute concentration of BCoV RNA assayed by ddPCR targeting the M gene is plotted on the y -axis. NIST stool matrix was spiked with 1:10 diluted (triangle) or undiluted (square) BCoV vaccine. Control samples with no spiked in RNA (none; circle) were included in duplicate to estimate LoB. U stands for undetermined and marks samples with no detectable RNA above LoB. Two-sided paired T tests were performed on n = 4 independent extractions for each spike-in condition. Associated statistics are summarized in Supplementary Data . Source data are provided as a Source data file.
