Information on column headers
Experiment description
The spread sheet includes meta annotations pertaining to the experiments performed. It is critical to know what samples were used and how the extracellular vesicles (EVs) are isolated. These information will allow the users to differentiate between crude and close-to-pure populations of EVs.
Experiment #	The experiment number can be any number (e.g., 21). Please give different experiment numbers if more than 1 sample (e.g., urine and serum) or more than 1 organism (e.g., mouse and human) is used.
PubMed ID	PubMed identifier provided for published article. It the article is unpublished – please include unpublished in this section. If the article is not indexed in PubMed, provide 0.
Species	Organism name. Please provide based on the taxonomical nomenclature (e.g., Homo sapiens)
Experiment Description	Provide the title of the article/study.
Sample	Provide the sample source in a broader context (e.g., colorectal cancer cells). In case of working with whole organisms, please provide the organism name in taxonomical nomenclature (e.g., Aedes aegypti).
Sample source	Provide two letter codes (ts – tissue, cl – cell lines, fl – fluid, wo – whole organism).
Cell line or tissue or fluid name	Provide the name of the cell line/tissue/fluid/organism (e.g., SW480)
Identifications	Provide the molecules identified (e.g., Protein, mRNA, miRNA or Lipids). When more than one kind of molecule is found in the study, use | to separate them (e.g., Protein|miRNA|mRNA).
Methods used	All the methods used in the study that identified the molecules (e.g., FACS, Western blotting). When more than one method was used in the study, use | to separate them (e.g., Western blotting|FACS).
Journal name	Provide the journal name as in PubMed. If unpublished, place “-“.
Authors as in PubMed	Author list as listed in the study (PubMed style).
Year published	Provide the year the article was published. If unpublished, place “-“.
Floatation	If density gradient centrifugation was used (sucrose, OptiPrep), provide the floatation density (e.g., 1.10 – 1.22 g/mL).
Isolation method	Provide the isolation method used. When multiple steps are used, separate them by | (e.g., Differential centrifugation|Filtration|Ultracenrifugation|Density gradient centrifugation|Exoquick|Immunoaffinity (EPCAM)|FACS (CD63)).
Vesicle type	Provide the vesicle type. It will be appreciated if the nomenclature in naming EVs follow the listed article Vesicle naming
Protein spread sheet
The spread sheet includes proteins identified in an EV study.
Entrez Gene ID	Provide the NCBI Entrez Gene ID. Why provide gene id rather than a protein (e.g., UniProt) or a RNA database accession (e.g., NCBI GI) identifier? While some experiments (high-throughput) provide sequence specific information many biochemical experiments that are commonly used in labs do not have sequence specific information (e.g., Western blotting – probing for BRCA1 which has multiple isoforms). For this reason, we obtain gene specific identifiers. Please make sure there is only one unique representation of a protein in the spread sheet.
Species	Organism name. Please provide based on the taxonomical nomenclature (e.g., Homo sapiens)
Experiment #	The experiment number has to be the exact number that was used in the experiment description spread sheet.
Method	Provide the method(s) that were used to identify the protein. As we require unique protein identifications, please place all the methods used to identify a protein separated by | (e.g., Western blotting|Mass spectrometry|Immunoelctron microscopy)
Sequence identifier (can be any protein sequence database)	Even though we obtain gene specific information for all the proteins, sequence specific data obtained by some techniques cannot be ignored. For this reason, we require sequence specific data (e.g., UniProt ID for the protein identified - P06238.2).
Mass spectromtery based protein spread sheet
The spread sheet includes proteins identified by mass spectrometry in an EV study.
Entrez Gene ID	Provide the NCBI Entrez Gene ID used in protein spread sheet.
mz	Provide mz obtained from the experiment.
z	Provide the charge.
Peptide score/E-value	Provide any peptide based score (e.g., Mascot ion score, SEQUEST Xcorr score)
Peptide start	Provide the peptide start in the protein sequence.
Peptide end	Provide the peptide end in the protein sequence.
E-value	Provide the peptide E-value.
Residue before	Provide the residue before the peptide in the protein sequence.
Peptide sequence	Provide the peptide sequence identified.
Residue after	Provide the residue after the peptide in the protein sequence.
Sequence identifier (can be any protein sequence database)	Provide the sequence identifier (e.g., UniProt ID for the protein identified - P06238.2).
Lipid spread sheet
The spread sheet includes lipids identified in an EV study.
Lipid name	Provide the name of the lipid identified. Please look at this spread sheet to have a list of lipids added in Vesiclepedia.
Species	Organism name. Please provide based on the taxonomical nomenclature (e.g., Homo sapiens)
Experiment #	The experiment number has to be the exact number that was used in the experiment description spread sheet.
Method	Provide the method(s) that were used to identify the lipid. As we require unique lipid identifications, please place all the methods used to identify a protein separated by | (e.g., Thin layer chromatography|Cytofluorographic analysis)
mRNA spread sheet
The spread sheet includes mRNA identified in an EV study.
Entrez Gene ID	Provide the NCBI Entrez Gene ID. Please make sure there is only one unique representation of a mRNA in the spread sheet.

Experiment #	The experiment number has to be the exact number that was used in the experiment description spread sheet.
Method	Provide the method(s) that were used to detect the mRNA. As we require unique mRNA identifications, please place all the methods used to identify the mRNA separated by | (e.g., RT-PCR|Microarray).
Sequence identifier (can be any nucleotide sequence database)	Provide sequence specific information (e.g., RefSeq nucleotide accession - NM_6239823.8).
miRNA spread sheet
The spread sheet includes miRNA identified in an EV study.
miRNA ID	Provide the miRNA ID (e.g., miR-223). Please make sure there is only one unique representation of a miRNA in the spread sheet.
Species	Organism name. Please provide based on the taxonomical nomenclature (e.g., Homo sapiens).
Experiment #	The experiment number has to be the exact number that was used in the experiment description spread sheet.
Method	Provide the method(s) that were used to detect the miRNA. As we require unique miRNA identifications, please place all the methods used to identify the miRNA separated by | (e.g., RT-PCR|Microarray).
Post-translational modifications (PTM) spread sheet
The spread sheet includes PTMs identified in an EV study.
Entrez Gene ID	Provide the NCBI Entrez Gene ID. Why provide gene id rather than a protein (e.g., UniProt) or a RNA database accession (e.g., NCBI GI) identifier? While some experiments (high-throughput) provide sequence specific information many biochemical experiments that are commonly used in labs do not have sequence specific information (e.g., Western blotting – probing for AKT phosphorylation). For this reason, we obtain gene specific identifiers. Please make sure there is only one unique representation of a protein in the spread sheet.
