armitage_estimate_sarea {httk}R Documentation

Estimate well surface area

Description

Estimate geometry surface area of plastic in well plate based on well plate format suggested values from Corning. option.plastic == TRUE (default) give nonzero surface area (sarea, m^2) option.bottom == TRUE (default) includes surface area of the bottom of the well in determining sarea. Optionally include user values for working volume (v_working, m^3) and surface area.

Usage

armitage_estimate_sarea(
  tcdata = NA,
  user_assay_parameters = NA,
  this.well_number = 384,
  this.cell_yield = NA,
  this.v_working = NA
)

Arguments

tcdata

A data table with well_number corresponding to plate format, optionally include v_working, sarea, option.bottom, and option.plastic OR with assay_component_endpoint_name corresponding to an entry in invitro.assay.params.

user_assay_parameters

option to fill in your own assay parameters (data table)

this.well_number

For single value, plate format default is 384, used if is.na(tcdata)==TRUE

this.cell_yield

For single value, optionally supply cell_yield, otherwise estimated based on well number

this.v_working

For single value, optionally supply working volume, otherwise estimated based on well number (m^3)

Value

A data table composed of any input data.table tcdata with only the following columns either created or altered by this function:

Column Name Description Units
well_number number of wells on plate
sarea surface area m^2
cell_yield number of cells cells
v_working working (filled) volume of each well uL
v_total total volume of each well uL
