Geminin is a crucial cell cycle regulatory protein that controls DNA replication and centrosome function. Geminin inhibits DNA replication by preventing the binding of the MCM complex into the pre-replication complex. Geminin accumulates during S, G2, and M phases, and disappears at the time of the metaphase-anaphase transition. Geminin functions as a homotetramer and interacts with DNA replication licensing factor CDT1. The interaction between Geminin and CDT1 is crucial to restrict DNA replication to once per cell cycle. Geminin is required for the formation of pluripotent cells in the developing embryo and essential for pluripotency in the embryonic stem cells. In ESCs, Geminin remains during G1 and sustains core pluripotency factors (Oct4, Sox2, and Nanog) by antagonizing the action of the chromatin remodeling protein BRG1.

Compatible Secondary Antibodies

Active Motif has developed a variety of high-quality secondary antibodies for most applications, with anti-rabbit and anti-mouse conjugates to a broad line of high-quality fluorescent molecules, as well as horse radish peroxidase (HRP).

Some products may be shipped at room temperature. This will not affect their stability or performance. Upon receipt, unconjugated antibodies may be stored at -20°C for up to 2 years. Fluorophore- & enzyme-conjugated antibodies should be stored at 4°C. Fluorophore-conjugated antibodies should be protected from light. Keep reagents on ice when not in storage; to avoid repeated freeze/thaw cycles, we recommend aliquoting items that will be stored frozen into single-use fractions prior to freezing.


This product is guaranteed for 6 months from date of receipt.
