Sample GSM5242325 Query DataSets for GSM5242325
Status Public on Apr 15, 2021
Title SARS-CoV-2 titration - 5 - rep2
Sample type SRA
Source name Saliva
Organism Homo sapiens
Characteristics technology: COV-ID
virus added: SARS-CoV-2
experiment: titration
viral concentration: 5
Treatment protocol Heat-inactivated SARS-CoV-2 (BEI Resources Cat. NR-52286) or H1N1 genomic RNA (Twist Biosciences Cat. 103001) was added to inactivated saliva prior to RT-LAMP.
Growth protocol Saliva was harvested from human donors
Extracted molecule total RNA
Extraction protocol We prepared 100x TCEP/EDTA buffer (250 mM TCEP, 100 mM EDTA, 1.15 N NaOH) 29. TCEP/EDTA buffer was added to human saliva at 1:100 volume, then samples were capped, vortexed to mix and heated in a thermocycler (95ºC 5 min, 4ºC hold) until ready to use for RT-LAMP.
1 μL of diluted LAMP material was used as a template for PCR using OneTaq DNA polymerase (NEB Cat. M0480L) with 100 nM each of custom dual-indexed Illumina P5 and P7 primers in either 10 or 25 μL reaction. PCR reactions were incubated as follows: (25 cycles of stage 1 [94ºC x 15 sec, 45ºC x 15 sec, 68ºC x 10 sec], 10 cycles of Stage 2 [ 94ºC x 15 sec, 68ºC x 10 sec], 68ºC x 1 min, 4ºC x ∞).

Description processed data file:
Data processing library strategy: COV-ID
Reads were filtered for optical quality using FASTX-toolkit utility fastq_quality_filter (, then cutadapt45 was used to remove adapters and demultiplex LAMP barcodes.
Genome_build: Reads were aligned to a custom index containing SARS-CoV-2 genome (NC_045512.2), Influenza H1N1 coding sequences (NC_026431.1, NC_026432.1, NC_026433.1, NC_026434.1, NC_026435.1, NC_026436.1, NC_026437.1, NC_026438.1), STATH coding sequence (NM_003154.3), and custom N2 spike sequence.
Supplementary_files_format_and_content: Tab-delimited text files containing summaries of aligned raw reads to control sequences and viral genomes for each experiment
