Molecular weight markers

Molecular weight markers, also known as protein ladders, are standardized mixtures of proteins with known sizes used in laboratory experiments like gel electrophoresis. They serve as reference points, allowing scientists to estimate the size of unknown proteins or molecules by comparing their position on the gel to the markers. The markers help ensure accuracy and consistency in identifying molecular sizes, making the analysis more reliable. These markers are essential tools for researchers to interpret their experimental results confidently.
