Definition / General
  • The two main types of immunostains for workup of minute foci of carcinoma or suspicious for carcinoma are a basal cell immunostain cocktail (consisting of cytoplasmic marker cytokeratin 34βE12, also called cytokeratin 903, plus nuclear marker p63), and alpha-methylacyl CoA racemase (AMACR, P504S)
  • These are often used together in a cocktail as a "triple stain"
