Western Blotting: A technique that uses antibodies specific for a protein of interest after SDS-PAGE separation, allowing for detection and quantification of that protein.
Molecular Weight Marker/ Ladder: These are mixtures of proteins with known sizes which are run alongside samples in SDS-PAGE so we can estimate the size of our sample proteins by comparing them to the marker bands.
Polyacrylamide Gel: The medium used in SDS-PAGE, which acts like a sieve, allowing smaller proteins to move faster than larger ones.
