[Histonet] Negative Control for Validation

[Sue]

What we do here is run a mix of expected negative and positive cases this way we are sure we are not getting exogenous staining.  Depending on the antibody we try to run at least a mix of 25 cases.  In some cases the antibody  proves difficult to get a large amount of positive cases and we make do with what we can get.  They are usually the read esoteric antibodies and you never find that many cases.
