Cyclin B1 and Ki-67 Assay
Description:
Cyclin B1 and Ki-67 Assay
Product Overview:
Millipore's HCS210 assay provides a complete immunofluorescence-based solution for identifying and quantifying cyclin B1 and Ki-67 expression in cellular imaging applications. The assay may be used to study agents which modulate the cell cycle, proliferation index, for cancer drug screening, and for in vitro toxicology studies. The reagents in the kit have been specifically optimized for HCS applications.
Background Information:
Cyclin B1
High Content Analysis of cyclin B1 expression is now a well-established research tool. The use of High Content Analysis of cyclin B1 expression to distinguish among G2, M, and G1/S phases of the cell cycle has recently been demonstrated. Additionally, High Content Analysis of Cyclin B1 expression has been used as a readout in cell cycle inhibitor profiling studies, illustrating the value of this approach in drug discovery applications.
Ki-67
The Ki-67 antigen (Ki-67) is a classic marker of cellular proliferation and has found widespread application in diagnostic, research and drug discovery applications. The Ki-67 antigen was originally defined by the monoclonal antibody Ki-67, the name being derived from the city of origin (Kiel) and the number of the original clone in the 96-well plate. Ki-67 antigen is preferentially expressed during late G1, S, G2 and M phase of the cell cycle, while resting, non-cycling cells (G0 phase) lack Ki-67 expression. Thus, Ki-67 is commonly used as a proliferation marker.

Storage Conditions:
When stored under the conditions indicated on the labels, the kit components are stable up to the expiration date. HCS Fixation Solution, HCS Immunofluorescence Buffer, HCS Wash Buffer, DMSO, Compound Dilution Buffer, and Plate Sealers should be stored at 2-8ºC. HCS Primary Antibodies, HCS Secondary Antibodies, Hoechst HCS Nuclear Stain, Camptothecin, Vinblastine Sulfate, Aphidicolin and Paclitaxel should be stored at -20ºC, avoiding repeated freeze/thaw cycles. (Note: If kit is expected to be used for multiple experiments, rather than a single use, thaw antibodies, nuclear stain and control compounds and dispense into appropriately sized aliquots. Store aliquots at -20ºC.)
Discard any remaining reagents after the expiration date.
