Immunohistochemistry (IHC)
Test Description

BCL2 is a protein associated with apoptosis regulation produced by the BCL2 gene and is comprised of an alpha and beta chain. BCL2 (clone SP66) shows negative reaction on reactive germinal centers and positive staining of neoplastic follicles in follicular lymphoma. This is useful in distinguishing between reactive and neoplastic follicular proliferation in lymphoid lesions. This is a sensitive antibody that may stain a greater proportion of follicular lymphomas than other BCL2 antibodies. See also BCL2 IHC.
