A polyclonal anti-Glut1 antibody (MYM) and a standard ABC immunoperoxidase technique were used to determine Glut1 expression in invasive squamous cell carcinomas (SCCs), SCC in situ, basal cell carcinomas (BCCs), melanomas, actinic keratoses (AKs), seborrheic keratoses, common acquired nevi, and scars with regenerative epidermal hyperplasia.
