RDI Divison of Fitzgerald Industries Intl  offers a wide line of  antibodies. Since no one antibody works best for all applications (neutralization, blotting, ELISA, etc), we offer many different types of antibodies to help solve this problem. Please inquire for other applications or types of antibodies not listed below.

Background: Mcm3 is a member of the Mcm protein family which are essential for the initiation of DNA replication. Although definite functions of the MCM proteins remain largely unknown, they have been implicated in the regulatory machinery allowing DNA to replicate only once in the S phase. The Mcm proteins are present at relatively constant throughout the cell cycle in actively proliferating cells, but bind to chromatin in a cell cycle specific manner. Mcm proteins bind to chromatin, before the cell cycle enters the S phase, and make chromatin competent for replication. During replication, MCM proteins dissociate from chromatin in a process that is accompanied by phosphorylation of several members of the Mcm family. Replicated chromatin lacks Mcm proteins and it is therfore unable to replicate within the same cell cycle. Mcm3 is expressed throughout the cell cycle (G1, S, G2, M pahses) but not in resting G0 cells. Because of its expression, Mcm3 can be used for cell proilferation marker.
