Recommended applications: HER2 IHC control with strong, moderate,  low and negative expressers.
 
Description: The array contains four cases of invasive ductual carcinoma of the breast.  All the tissues were from surgical resection. They were fixed in 10% neutral buffered formalin for 24 hours and processed using identical SOPs. Sections were picked onto Superfrost Plus or Startfrost slides.  As validated by IHC, A1 is a strong (+++) expresser, A2 is a moderate (++) expresser, A3 is a weak expresser, while A4 is a negative/weak positive case of the HER2 molecule. 

Notes: Bake at 60C for 30 minutes before use. If antigen retrieving is needed, it is always a good idea to start with a protocol with weak to mild strength.
