Cyclin D1 Antibody / CCND1

Cyclin D1 (CCND1), one of the key cell cycle regulators, is a putative proto-oncogene overexpressed in a wide variety of human neoplasms. About 60% of mantle cell lymphomas (MCL) contain a t(11; 14)(q13; q32) translocation resulting in over-expression of Cyclin D1. This antibody is useful in identifying mantle cell lymphomas (CCND1+) from CLL/SLL and follicular lymphomas (CCND1-). Occasionally, hairy cell leukemia and plasma cell myeloma weakly express CCND1.
