Fifteen blanks were analyzed for serum samples, and the blank values, adjusted to a nominal sample size of 2 g and a mean lipid value of 0.69%, were 0.87 and 2.12, 0.00 and 0.09, 0.12 and 0.23, 0.80 and 0.99, and 0.00 and 3.3 (ng g 1 lw) for TBB, TBPH, BB-153, BDE-153, and DBDPE, respectively.
Eighteen blanks were performed for milk samples, and the median and mean values, adjusted to a nominal sample size of 5 g and a mean lipid value of 2%, were 0.15 and 0.23, 0.00 and 0.05, 0.02 and 0.03, 0.14 and 0.26, and 0.00 and 0.09 (ng g 1 lw) for TBB, TBPH, BB-153, BDE-153, and DBDPE, respectively.
A 2-mm probe tip was placed over the predetermined skin site and adjusted to a tip-to-sample distance of 100 µm under tip oscillation settings of 94.8Hz frequency.
The adjusted means are sample means adjusted to a mean body weight and regression coefficient within a group [ 21].
The acidified water samples was neutralized and adjusted to a pH of 7. The water samples were treated with concentrated nitric acid following standard procedures of the American Public Health Association, filtered with 0.45 micron filters into 10 mL volumetric flasks and made up to the mark with deionized water (APHA-AWWA-WPCF 1981).
The dialyzed sample was adjusted to a pH value of 3.0 to 4.0 and then purified by centrifugation.
The sample was adjusted to a final concentration of 1 M (NH4 2SO4 by the addition of buffer C (3 M (NH4 2SO4, 20 mM Tris-HCl/pH 7.5).
Then each sample was adjusted to a concentration of 10 cells/tube and stained with Annexin V-FITC (Santa Cruz Biotechnology, Inc).
About 2000 ng RNA was taken from each sample and adjusted to a volume of 12 μL with RNase-free water.
The dialysed sample was adjusted to a salt concentration of 75 mM, loaded onto the Resource Q column and eluted with a linear gradient of 75 500 mM NaCl in 10 bed column volumes.
