Newcomer supply CD45, Leucocyte Common Antigen (LCA) control slides are for the positive immunohistochemical staining of CD45, routinely used in the differential diagnosis of undifferentiated neoplasms, whenever malignant lymphoma is suspected

Staining Results:
CD45, LCA positive expression will stain brown membrane staining.
Adipose will stain negative.
Nuclei will stain blue.

These positive control slides are intended to be used to verify histological techniques and reagent reactivity. These slides are to be used for the qualitative purpose of determining positive or negative results, and are not intended to be used for any quantitative purpose.

A positive result is highly indicative of lymphoid or myeloid origin.
