SDS-PAGE蛋白质次高分子标准/次高分子MARK

 Description
Application SigmaMarkers are designed for use with Laemmli SDS-PAGE, the PhastSystem （Pharmacia） and Schagger and von Jagow SDS-PAGE （Tricine）. SigmaMarkers cover the range of molecular weights common to most proteins or their subunits. The wide, high and low range markers are lyophilized with sample buffer so that they are ready-to-use after reconstitution with deionized water. The markers are formulated to yield a distribution of well-defined bands of approximay equal intensity after electrophoresis and Coomassie blue staining.
Other Notes Protein （mol. wt.）
Glyceraldehyde-3-phosphate dehydrogenase, rabbit muscle （36,000）
Ovalbumin, chicken egg （45,000）
Glutamic dehydrogenase, bovine liver （55,000）
Albumin, bovine serum （66,000）
Phosphorylase B, rabbit muscle （97,000）
β-Galactosidase, E. coli （116,000）
Myosin, porcine heart （200,000）
  Will yield bands for the following seven proteins from the SigmaMarker list with Coomassie Blue staining.
Reconstitution Reconstitution with 100 μl of deionized water results in a solution containing 2-3.5 mg of protein per ml of 62 mM Tris-HCl, pH 6.8, 1 mM EDTA, 4% sucrose, 0.5% dithiothreitol, 2% SDS, and 0.0005% bromophenol blue.
