## Sequence data for the Somalogic SOMAscan assay

### Description

Sequence data for the SOMAmers in the 1129 and 1310 panels of the Somalogic SOMAscan assay.

### Format

A data frame with the following columns.

AptamerId

  Character, primary key. The identifier of the aptamer sequence identified using SELEX. It consists of an SomaLogic SeqId truncated at the underscore, to remove its sequence version number.

SomaId

  Character. The SomaLogic identifier for the protein target. For the 1129 and 1310 assays, there is a one-to-one correspondence between SeqId and SomaId, but in theory there is a many-to-one correspondence.

Target

  Character. The name of the protein target, from the protein standard supplier, sometimes with additional annotation by SomaLogic.

TargetFullName

  Character. The name of the protein target, from UniProt.

UniProt

  List of character vectors. UniProt IDs for the protein target.

EntrezGeneID

  List of character vectors. Entrez Gene IDs for the gene associated with protein target.

EntrezGeneSymbol

  List of character vectors. Entrez Gene symbols for the gene associated with protein target.

Organism

  Either "Human" or the name of a virus.

Units

  Should always be RFU, short for Relative Fluorescence Units.

Type

  The protein standard source for the original SELEX performed for the sequence. "Protein" refers to human protein; a few sequences used rat protein standard sources in the SELEX.

PlasmaDilution

  What dilution factor is used in plasma?

SerumDilution

  What dilution factor is used in serum?

IsIn1129Panel

  Is the aptamer in the 1129 panel of the SOMAscan assay?

IsIn1310Panel

  Is the aptamer in the 1310 panel of the SOMAscan assay?
