The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Application notesIHC-P: 1/100 - 1/500. Antigen retrieval with citrate buffer may enhance staining.
Note: expected to work on frozen sections.

FunctionRequired for cytokinesis. Essential for the structural integrity of the cleavage furrow and for completion of cleavage furrow ingression.
Tissue specificityUbiquitously expressed. Present at highest levels in the brain, at high levels in the placenta and testis, at intermediate levels in the intestine, ovary, skeletal muscle and thymus and at lower levels in heart, kidney, liver, lung, pancreas, prostate and spleen. Overexpressed in many tumor types including breast, colorectal, endometrial, hepatic, kidney, lung, ovarian and pancreatic tumors.
Sequence similaritiesContains 1 PH domain.
Developmental stageExpressed in fetal brain, heart, kidney, liver, lung, skeletal muscle, spleen and thymus. In dividing cells expression increases during S and G2 phases, peaks at mitosis and subsequently drops as cells enter G1 phase.
Post-translational modificationsPhosphorylated during mitosis. Ubiquitinated, and this requires FZR1/CDH1.
Cellular localizationNucleus. Cytoplasm > cytoskeleton. Cytoplasm > cell cortex. Mainly found in the nucleus during interphase. Colocalizes with cortical F-actin upon nuclear envelope breakdown in mitosis and subsequently concentrates in the area of the prospective contractile ring in anaphase. This pattern persists until telophase, when the protein becomes concentrated in the midbody.
