Is your Western Blot showing a band at the wrong molecular weight? This is one of the most common frustrations in the lab, but it's not a dead end. An unexpected band size is often a critical clue, not a failed experiment. The theoretical calculated weight from amino acid sequence rarely matches the observed weight on a gel. This discrepancy can be caused by a host of biological reasons from post-translational modifications like glycosylation to protein cleavage, splice varia
