(Non-denatured proteins run according to their molecular weight, shape, and charge.) You will run a reference ladder containing proteins of known molecular weight and amount to determine the size and concentration of your purified FKBP12 protein. Since denatured proteins are linear, they will move through the gel at a speed inversely proportional to their molecular weight, just like DNA on agarose gels. SDS is an ionic surfactant (or detergent), which denatures the proteins and coats them with a negative charge. You will use sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) to evaluate your purified protein. Over time fragments of similar length accumulate into “bands” in the gel. The distance a nucleic acid or amino acid fragment travels is inversely proportional to the log of its length. The larger molecules get entwined in the matrix and are stalled the smaller molecules wind through the matrix more easily and travel farther away from the well. The molecules to be separated enter the matrix through a well at one end and are pulled through the matrix when a current is applied across it. DNA, RNA and proteins are the molecules most often studied with this technique agarose and acrylamide gels are the two most common sieves. 2.4 Part 4: Concentrate FKBP12 protein solutionĮlectrophoresis is a technique that separates large molecules by size using an applied electrical field and a sieving matrix.2.3.2 Part 3b: Prepare Working Reagent (WR) and measuring protein concentration.2.3.1 Part 3a: Prepare diluted albumin (BSA) standards.2.3 Part 3: Measure protein concentration.2.2 Part 2: Visualize purified protein with polyacrylamide gel electrophoresis (PAGE).2.1 Part 1: BE Communication Lab workshop.Yakisoba Pan - Sikkenine - Torimeshi Ration - Veg.
