Why is my Phospho-p53 (Ser15) antibody cross-reacting with the prestained protein marker?

We have confirmed in-house that our Phospho-p53 (Ser15) Antibody #9284 and Phospho-p53 (Ser15) (D4S1H) Rabbit mAb #12571 cross-react with some prestained protein markers. We are unsure as to why this is occurring. To help avoid this, we recommend using a biotinylated marker without the use of a prestained marker.
