Experiment I was designed for evaluating the effects of two P fertilizer sources (Sou): SSP and MAP combined with three methods of fertilizer application (Me): WS, side-banded (SB) or broadcast anticipated (BA) applying 16.2 kg P ha−1.
Dishes (60 mm) were coated with 1% SeaPlaque agarose (BioWhittaker Molecular Applications, Rockland, ME, USA) dissolved in DMEM/10% FBS.
The digested products were separated on a 4% NuSieve agarose gel (Bio Whittacker Molecular Applications, Rockland, ME, USA) and the genotype determined by the banding pattern observed.
Agarose was bought from BioWhittaker Biological Applications (Rockland, ME, USA) and Ready Protein+ scintillation liquid from Beckman Coulter Inc. (Fullerton, CA, USA).
A total reaction volume of 25 μl contained 12.5 μl of Master Mix, 2 μl of 25 m M MgCl2, and 0.25 μl of 25 × SyBr Green (BioWhittaker Molecular Applications, Rockland, ME, USA).
A 5% Long Ranger/6 mol/l urea gel (Biowhittaker Molecular Applications, Rockland, ME, USA) was used for rapid fragment detection using the ABI Prism 377 DNA Sequencer (Perkin-Elmer, Foster City, CA, USA) at the Dana Farber Cancer Institute Molecular Biology Core Facility and the Harvard Center for Cancer Prevention, Boston, MA, USA.
Sequencing products were purified through Sephadex G-50 columns (Sigma-Aldrich, St . Louis MO), and electrophoresed on 4.75% Long Ranger gels (BioWhittaker Molecular Applications, Rockland, ME) on an ABI Prism 377 Sequencer (Applied Biosystems).
I went to a college preparatory high school where I was blessed to have two professionals looking over my applications with me, and my highly educated mother helping me design strategy.
Yet, some are wondering aloud whether Silicon Valley has jumped the shark, investing now in trivial applications and me-too companies.
Briefly, 24-well plates were coated with 1% Seaplaque agarose (BioWhittaker Molecular Application, Rockland, ME) and tumor cells (2 × 105 cells in 1 ml complete medium) were plated on top of the solidified agarose.
