But, said Dan Goldhaber, a professor at the University of Washington with extensive experience in teacher-evaluation research, "The ultimate test is: Is this having positive, measurable effects on teachers and students?" In L.A., it's still too early to say, even more than six years into a sweeping endeavor to revamp how instruction is measured and improved. .
GAGs was assessed by the Blyscan Glycosaminoglycan Assay Kit (Biocolor) following the manufacturer's instructions; absorbance was measured at 656 nm using a microplate reader.
Cardiovascular markers were measured from mouse plasma following the commercial assay kit instructions: glucose was measured with the Wako Autokit Glucose (Wako Pure Chemical Industries, Ltd, Osaka, Japan), and insulin was measured using the Millipore Rat/Mouse Insulin enzyme-linked immunosorbent assay (ELISA) (Merck Millipore, Billerica, MA, USA).
After the last wash, CellTiter-Glo™ (Promega Corp., Madison, WI) was added to all the wells per the manufacturer's instructions and luminescence was measured using a Beckman DTX 880 plate reader.
Cells were processed following manufacturer's instructions and absorbance was measured at 550 nm on a microplate reader.
The MTS assay was performed according to the manufacturer's instructions and absorbance was measured at 490 nm using a Victor3 Multilabel Counter 1420 042 (Perkin Elmer, MA, USA).
According to the manufacturer's instructions, PCT level was measured by an electrochemiluminescence immunoassay (ECLIA) B.R.A.H.M.S. PCT ELECSYS® using an automated Roche Elecsys and Cobase immunoassay analyser [ 20].
Genotyping was carried out in accordance with the kit manufacturer's instructions and fluorescence was measured with a fluorescence polarization reader (Victor-Wallace from Perkin Elmer Life Sciences, Boston, MA, USA) at 20, 25 and 35 cycles.
