产品说明

一般描述

Ras proteins are small GTP-binding proteins which, unlike the heterotrimeric G-proteins, contain all GTPase and effector functions within a single polypeptide. At least three isoforms of Ras exist, Ki-Ras, Ha-Ras and N-Ras, with distinct expression patterns but similar signaling activity. Ras is palmitoylated and farnesylated at the carboxy terminus, anchoring it in the membrane. In resting cells, Ras is loaded with GDP, and is activated subsequent to growth factor stimulation of receptors, which recruit Ras Guanine nucleotide Exchange Factors to the plane of the membrane. Proximity of exchange factors to the Ras proteins causes release of GDP, and its replacement by GTP. In its GTP-bound form, Ras binds several proteins, including Raf, RalGDS and PI3 Kinase. Inactivation of Ras occurs by GTP hydrolysis, which is greatly accelerated by RasGAP or NF-1, two known Ras GTPase Activating Proteins. It is possible to assay for Ras activation by incubation of lysates with the Ras-binding domain of Raf-1, which selectively binds to Ras:GTP.

储存及稳定性

Stable for 1 year at -20ºC from date of receipt.
Handling Recommendations: Upon receipt, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.

分析说明

Control
Included Positive Antigen Control: Catalog # 12-301, non-stimulated A431 lysate. Add 2.5 μL of 2-mercaptoethanol/100 μL of lysate and boil for 5 minutes to reduce the preparation. Load 20 μg of reduced lysate per lane for minigels.

其他说明

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.
