Fup UC Level-2 Heldout Example Data set

Description

The unverified level-2 samples from mass spectrometry measurements of plasma protein binding (PPB) via ultracentrifugation (UC) for per- and poly-fluorinated alkyl substance (PFAS) samples. Experiments were led by Dr.s Marci Smeltz and Barbara Wetmore \insertCitesmeltz2023plasmainvitroTKstats. This data set is a subset of experimental data containing samples for 0 test analytes/compounds. No data samples are unverified.

Usage

fup_uc_L2_heldout

Format

A level-2 data.frame with 0 rows and 24 variables:

Lab.Sample.Name

Sample description used in the laboratory

Date

Date the sample was added to the MS analyzer

Compound.Name

Name of the test analyte/compound

DTXSID

DSSTox Substance Identifier (CompTox Chemicals Dashboard - CCD)

Lab.Compound.Name

Compound as described in the laboratory

Sample.Type

Type of UC sample

Dilution.Factor

Number of times the sample was diluted

Calibration

Identifier for mass spectrometry calibration – usually the date

ISTD.Name

Name of the internal standard (ISTD) analyte/compound

ISTD.Conc

Concentration of ISTD (uM)

ISTD.Area

Peak area of internal standard (ISTD) compound (pixels)

Area

Peak area of analyte (target compound)

Analysis.Method

General description of chemical analysis method

Analysis.Instrument

Instrument(s) used for chemical analysis

Analysis.Parameters

Parameters for identifing analyte peak (for example, retention time)

Note

Any laboratory notes about sample

Level0.File

Name of the laboratory data file from which the level-0 sample data was extracted

Level0.Sheet

Name of the Excel workbook 'sheet' from which the level-0 sample data was extracted

Test.Compound.Conc

Measured concentration of analytic standard (for calibration curve) (uM)

Test.Nominal.Conc

Expected initial concentration of chemical added to T1 sample (uM)

Biological.Replicates

Identifier for measurements of multiple samples with the same analyte

Technical.Replicates

Identifier for repeated measurements of one sample of a compound

Response

Response factor (calculated from analyte and ISTD peaks)

Verified

If "Y", then sample is included in the analysis. (Any other value causes the data to be ignored.)
