This conversion factor is used to convert concentrations measured relative to cell protein to that relative to cell volume.
Taken together, this model (Equations 1– 16) allowed us to convert concentrations of chemotaxis proteins into time-dependent behavior and phenotypic parameters.
When blood results were missing (e.g., n = 30 for cord blood), the average ratio between the two (e.g., 4.25 to convert concentrations in maternal hair to cord blood) was used to estimate the blood concentration.
For converting concentrations given in μmol/g to molarities we assumed brain tumor tissue density to be similar to normal human brain tissue measuring 1.054 +/- 0.014 g/cm[ 19].
TBT tissue concentrations are given on a dry weight basis as Sn and can be converted to concentrations on TBT cation basis by multiplying by 2.44.
The random numbers were converted to concentrations by multiplication with the standard deviation and addition of the mean of the known concentrations.
Particulate is extracted followed by absorbance measurements which can be converted into concentrations using a PM standard curve.
Later on, the absorbance of samples was converted to concentrations using the calibration curve for cobalt ions.
The peak areas obtained from chromatographic analysis of all injected samples were converted to concentrations using the calibration responses of the neurochemical standards.
Protein quantities are recorded as relative fluorescent units (RFU), which can be converted to concentrations with standard curves.
