SDS-PAGE蛋白质超低分子量多肽

 Description
Application Designed for molecular weight determinations on silver stained SDS-PAGE （Laemmli） gels. The proteins supplied in these markers cover the range of molecular weights common to most proteins or their subunits. The markers are formulated to yield a distribution of well-defined bands of approximay equal intensity with low background after electrophoresis and staining using either ProteoSilver™ （PROTSIL1） or ProteoSilver™ Plus （PROTSIL2）.
Other Notes Will yield 9 bands with silver staining:
• α2-Macroglobulin, 180,000 Da
• β-Galactosidase, E. coli, 116,000 Da
• Phosphorylase b, Rabbit Muscle, 97,000 Da
• Serum Albumin, Bovine, 66,000 Da
• Fumarase, Porcine Heart, 48,500 Da
• Carbonic Anhydrase, Bovine Erythrocytes, 29,000 Da
• β-Lactoglobulin, Bovine Milk, 18,400 Da
• α-Lactalbumin, Bovine Milk, 14,200 Da
• Aprotinin, Bovine Lung, 6,500 Da
 
Packaging Vial contains 200 μl of protein markers. Supplied with one vial of 2× Laemmli sample buffer （S3401）.
Reconstitution Dilute the concentrate between 1:15 and 1:30 depending on the amount of protein loaded in the other lanes. Recommended loading volumes are 10 μl per well for mini gels （10 × 10 cm） or 20 μl per well for standard format gels （16 × 18 cm）.
