Immunohistochemistry (IHC)
Test Description
B-cell lymphoma 2 (BCL2) was the first of the translocation-associated proteins to be identified in lymphoma. Most cases of follicular lymphoma have a [t(14;18)] translocation, resulting in BCL2 overexpression. Overexpression of BCL2 in activated diffuse B-cell lymphoma may predict disease progression. BCL2 is also expressed in a wide range of other neoplasms. See also BCL2 (SP66) IHC
