Accuracy and precision in mouse tumor homogenates.

Nominal Conc. (nmol/g)	Intra-day (n=3)		Inter-day (n=6)
	Accuracy (%)	Precision (% RSD)	Accuracy (%)	Precision (% RSD)
2000	96.8	3.05	98.1	4.03
200	101	3.39	104	4.11
20	95.2	1.69	98.2	6.03

Inter and intra-day precision and accuracy for FGAR in EL4 tumor homogenates were determined by analyzing replicates (n=3/day) of spiked samples at 3 different concentration levels over 2 subsequent days. Statistics for inter-day evaluation are generated from n=6 samples.
