IHC control tissue array for progesterone receptor, 3 cases, 6 samples (2mm)

IHC control array containing 3 breast cancer cases of strong, moderate, low/negative progesterone receptor (PR) expressers in duplicates

All the tissues were fixed in 10% neutral buffered formalin for 24 hours and processed using identical SOPs. Sections were picked onto Superfrost Plus or Startfrost Adhesive slides. They all have a guaranteed six months' shelf-life at 4C from the date of shipment. There may be >5% tissue core losses for a slide. But the core retention rate should be >90%.

Please bake the slides 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.
