It is the difference in the composition of sample and dialysis buffer solutions that creates the concentration-differential across the membrane that drives the dialysis process. Using a high buffer-to-sample volume-ratio helps to mainta...
The effect of NaOH and N-acetyl-l-cysteine (NAC) concentration, mass:volume, agitation and extraction temperature on the recovery of alkaline soluble proteins from milled oven-dried Palmaria palmata was studied. The contribution of physical (osmotic shock and shearing) along with enzymatic cell disr...
They cited reasons for unidentifiability as insolubility of edestin in the homogenation buffer (pH 7.5) used in their 2-DE protein extraction41. We encountered similar difficulty with Salvia hispanica. Previous studies investigating the chemical properties of chia seed proteins uncovered a strong ...
These results indicate that the proximate composition of the soybean sample used in this study is comparable to those used in previous studies. 3.2. The Response Surface Optimization 3.2.1. Experimental of the Response Surface Methodology The experimental protein extraction yield (Y1) and amine ...

We also compare the proteomic molecular profiles obtained through e-biopsy with state-of-the-art solid tissue lysis buffer extraction. In particular, we show that proteomic profiles obtained by e-biopsy from 4T1 mice tumors in vivo are tissue specific, consistent, reflect tumor protein expression ...

Here we investigated only the protein fraction that is soluble in a low ionic strength buffer in order to resolve the soluble proteins (mostly enzymes and regulatory proteins) from the structural proteins of the contractile apparatus (particularly the very abundant actin and myosin). Figure 1 Two-...
(MM301, Retch, Haan, Germany), proteins were extracted by mixing 2 g of material with extraction buffer (25 mM Tris-HCl pH 7.5, 15 mM MgCl2, 5 mM EGTA, 0.1% (v/v) NP40, 1 mM dithiothreitol, 5% (v/v) ethylenglycol and 1 mM phenylmethylsulfonyl fluoride). Following...
In total, 2 mg of proteins were incubated in the lysis buffer for 2 h at room temperature with gentle mixing and then precipitated using the methanol/chloroform extraction method77. The pellets were resuspended in 1 ml of binding buffer (100 mM Tris pH 7.2, 150 mM NaCl, 25...
