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.）
Aprotinin, bovine lung （6,500）
α-Lactalbumin, bovine milk （14,200）
Trypsin inhibitor, soybean （20,000）
Trypsinogen, bovine pancreas （24,000）
Carbonic anhydrase, bovine erythrocytes （29,000）
Glyceraldehyde-3-phosphate dehydrogenase, rabbit muscle （36,000）
Ovalbumin, chicken egg （45,000）
Albumin, bovine serum （66,000）
Will yield eight protein bands 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.
