[Histonet] ER/PR Control

[Terri Braud]

Hi Barbi - 
We are somewhere in-between with our ER/PR Controls.  When performing lot to lot validations, we use our in-house control, which only has a 0 and a 3+, BUT we also use a commercially prepared control that contains 4 cores, 0. 1+, 2+, 3+.  Once the new lot of antibody has been validated against both controls, then we only use our inhouse control with the 0 and 3+.  It just saves on time and money.
Hope this helps, Sincerely, Terri

Subject: [Histonet] ER/PR controls
For anyone making in-house ER/PR controls could you comment on what tissue you have in your control block -- one piece of positive tumor regardless of reactivity strength 1+, 2+, 3+ (weak, medium, strong) or multiple pieces to represent each level of reactivity?

Also, does anyone order commercially their ER/PR controls to achieve this level of representation in their control block?
Any thoughts are appreciated - thank you.
