Separate 150kda Protein From Smaller Molecular Weight Protein

Proteins with lower molecular weight travel faster. Therefore, a protein that is closer to the positive electrode has a smaller molecular weight than a protein that is farther from the positive electrode. The purified protein has migrated to between the markers of 45,000 and 22,000 molecular weight. The protein is carbonic anhydrase. 7.

For 150 kDa I recommend a 6% gel, another advantage is that lower. remember that the proteins are already denatured and mostly separated one from each.

Novex Sharp Unstained Protein Standard is designed for accurate and convenient molecular weight estimation of proteins during SDS-PAGE and western blotting. The standard consists of a wide range of molecular weight bands consisting of 12 proteins in the range of 3.5–260 kDa.

Such sets of known proteins are called protein molecular weight (or mass) markers or protein ladders. A standard curve can be constructed from the distances migrated by each marker protein. The distance migrated by the unknown protein is then plotted, and the molecular weight is extrapolated from the standard curve.
