The Annexin V-FITC Early Apoptosis Detection Kit enables researchers to identify early apoptotic cells within a cell population. Annexin V-FITC conjugated protein binds to cell surfaces expressing phosphatidylserine, an early apotosis marker. Cells stained with propidium iodide (PI), a non-cell-permeable DNA dye, indicate necrotic cells. Cells stained with both PI and annexin V-FITC demonstrate later stage apoptosis and early necrosis. This kit provides enough reagent to perform 100 assays, based on a 250 μl assay volume.

The Active Ras Detection Kit provides all reagents necessary for measuring activation of Ras GTPase in the cell. GST-Raf1-RBD fusion protein is used to bind the activated form of GTP-bound Ras, which can then be immunoprecipitated with glutathione resin. Ras activation levels are then determined in western using a Ras mouse mAb.

Human, Mouse

Application Methods: Immunoprecipitation, Western Blotting

Background: The Ras superfamily of small GTP-binding proteins (G proteins) comprise a large class of proteins (over 150 members) that can be classified into at least five families based on their sequence and functional similarities: Ras, Rho, Rab, Arf, and Ran (1-3). These small G proteins have both GDP/GTP-binding and GTPase activities and function as binary switches in diverse cellular and developmental events that include cell cycle progression, cell survival, actin cytoskeletal organization, cell polarity and movement, and vesicular and nuclear transport (1). An upstream signal stimulates the dissociation of GDP from the GDP-bound form (inactive), which leads to the binding of GTP and formation of the GTP-bound form (active). The activated G protein then goes through a conformational change in its downstream effector-binding region, leading to the binding and regulation of downstream effectors. This activation can be switched off by the intrinsic GTPase activity, which hydrolyzes GTP to GDP and releases the downstream effectors. These intrinsic guanine nucleotide exchange and GTP hydrolysis activities of Ras superfamily proteins are also regulated by guanine nucleotide exchange factors (GEFs) that promote formation of the active GTP-bound form and GTPase activating proteins (GAPs) that return the GTPase to its GDP-bound inactive form (4).
