[13C3]-atrazine served as the internal standard for the quantification of pesticides, [13C3]-caffeine for the quantification of pharmaceuticals and personal care products and finally [13C3]-estradiol served for the quantification of estrogens and progestogens.
Landscape indices are popular for the quantification of landscape pattern.
For the quantification of redox species, external calibration was employed.
For the quantification of mRNA, gene expression quantification using "Assay-on-demand" for Cdkn1a, HoxB4, c-Myc, SCL, PAX5, E2A, ID2, BLNK, CD79 and D19 was performed according to the manufacturer's instructions (Applied Biosystems).
A different approach can be used for the quantification of protein complexes, e.g. quantification using concatenated proteotypic peptides or QconCAT (Pratt et al. 2006).
All samples were subjected to two reactions of amplification, one for the quantification of methylated MDR1 and the other for quantification of an internal reference gene (β-actin) using primers and probes reported elsewhere [ 11, 23].
Low coefficient of variation (CV%: 10 22%) and high correlation (R2 > 0.96) values were obtained for the quantification of the spiked peptides, allowing quantification of these peptides in the low fentomole range, correct group discrimination and selection of "specific" markers using principal component analysis.
Sandwich ELISA was used for the quantification of each histone.
Three quantities for the quantification of multicellular movement were introduced.
Calibration curve for the quantification of DFC from plasma.
For Anderson, "the quantification of attention and reputation is now a global endeavor...a market we all now play in, whether we know it or not".
