Rabbit anti Human Aurora-B kinase antibody detects human Aurora-B kinase (AurB), a serine/threonine kinase which is the enzymatic core of the Chromosomal Passenger Complex (CPC). This complex functions in chromosome alignment and separation, histone modification, and cytokinesis. CPC also includes three non-enzymatic subunits known as the inner centromere protein (INCENP), survivin, and borealin, which determine the activity, localisation, stability, and possibly even the substrate specificity of AurB.

Two CPCs exist during mitosis- one containing all four members, and another consisting of INCENP and AurB. Quaternary CPC functions during chromosome alignment and cytokinesis, whereas the INCENP-AurB complex may be responsible for modifying histone H3.

AurB is overexpressed in a number of tumours, including primary breast and colon tumour samples. Its expression in tumours seems to be linked with Aurora-A kinase, suggesting a feedback mechanism between the two proteins.

Storage Information

This product is shipped at ambient temperature. It is recommended to aliquot and store at -20°C on receipt. When thawed, aliquot the sample as needed. Keep aliquots at 2-8°C for short term use (up to 4 weeks) and store the remaining aliquots at -20°C.

Avoid repeated freezing and thawing as this may denature the antibody. Storage in frost-free freezers is not recommended.
