In recent years, the study of cancer biology has elicited a close look at key factors involved in the regulation of cell cycle. In particular, much attention has been focused on factors that are involved in programmed cell death (apoptosis). IMGENEX offers a large selection of antibody reagents to factors that are involved in the cascade of a number of key factors including oncogenes and tumor suppressor gene products and various factors involved in neurobiology including neurotransmitter receptors.
