Two-Dimensional Gel Electrophoresis:Article Title: A fractionation method to identify qauntitative changes in protein expression mediated by IGF-1 on the proteome of murine C2C12 myoblasts
Article Snippet: Subsequently, Bradford assays (Pierce, Rockford, IL.) were performed to determine the new protein concentration. .. Samples containing 75–200 μg of fractionated cytoplasmic proteins were diluted in 2D electrophoresis buffer (2 M thiourea, 5 M urea, 0.25% CHAPS, 0.25% Tween-20, 0.25% SB-3, 10% isopropanol, and 12.5% water-saturated butanol) containing 15 mg DTT and 0.5% ampholytes (pI ranges 3–10 or 5–8; Bio-Rad; Hercules, CA) to a final volume of 0.2 ml, and passively absorbed onto immobilized pH gradient strips (pI ranges 5–8 or 3–10 NL (non-linear); Bio-Rad) for 4 hours at 20°C followed by active rehydration (50 V at 20°C) for 8 hours. .. Isoelectric focusing was performed for 35,000 V-h on a Protean IEF System (Bio-Rad), electrophoresis with the Criterion gel system (Bio-Rad).
Article Title: Trafficking of cholinesterases and neuroligins mutant proteins An association with autism
Article Snippet: NL proteins were immunoprecipitated with Flag antibodies (Sigma) and Protein A/G beads (Pierce) for 12 h at 4 °C. .. The beads were washed and resuspended in 2D electrophoresis buffer (2 M thiourea, 5 M urea, 0.25% CHAPS, 0.25% Tween-20, 0.25% SB-3, 10% isopropanol, and 12.5% water saturated butanol) containing 15 mg DTT and 0.5% ampholytes (p I ranges 3-10; BioRad), and passively absorbed onto immobilized pH gradient strips (p I range 3-10 NL; BioRad) for 4 h at 20 °C followed by active rehydration (50 V at 20 °C) for 8 h. Isoelectric focusing was performed for 35,000 V h on a Protean IEF System (BioRad), followed by traditional SDS-PAGE using the Criterion gel system (BioRad). ..
Article Title: Differential Regulation of Disheveled in a Novel Vegetal Cortical Domain in Sea Urchin Eggs and Embryos: Implications for the Localized Activation of Canonical Wnt Signaling
Article Snippet: The protein concentrations were determined using the Bradford assay (Quick Start Bradford Dye Reagent, BIO-RAD) and then the samples were desalted using the ReadyPrep 2D cleanup kit (BIO-RAD). .. For 2D SDS-PAGE 40 μg of total protein of each sample was solubilized in 125 μl of 2D electrophoresis buffer (ReadyPrep 2D Rehydration/Sample Buffer 1; 7 M urea, 2 M thiourea, 1% (w/v) ASB-14, 40 mM Tris, 0.001% Bromophenol Blue, BIO-RAD) with the addition of 25 mM DTT, 4% (w/v) CHAPS, and 0.2% Bio-Lyte pH 3-10/4-7 (2:1)(BIO-RAD). .. Samples were loaded on an immobilized pH gradient (IPG) ReadyStrips 4-7 (BIO-RAD) and isoelectrofocused with the Protean IEF cell (BIO-RAD) by applying a total of 10,000 V-hr according to the ReadyStrip IPG Instruction Manual (BIO-RAD).
