General description

Cyclin D1, one of the key cell cycle regulators, is a putative proto-oncogene overexpressed in a wide variety of human neoplasms. Cyclins are proteins that govern transitions through distinct phases of the cell cycle by regulating the activity of the cyclin-dependent kinases. In mid-to-late G1 phase of the cell cycle, cyclin D1 shows a maximum expression following growth factor stimulation. Anti-cyclin D1 has been successfully employed and is a promising tool for further studies in both cell cycle biology and cancer associated abnormalities. This antibody is useful for separating mantle cell lymphomas (cyclin D1 positive) from CLL/SLL and follicular lymphomas (cyclin D1 negative). Hairy cell leukemia and plasma cell myeloma can weakly express Cyclin D1.


Cyclin D1 Positive Control Slides, Product No. 241S, are available for immunohistochemistry (formalin-fixed, paraffin-embedded sections).
