Technical Data
HRAS, Palmitoylated (GTPase HRas, Transforming protein p21, p21ras, H-Ras-1, c-H-ras, Ha-Ras, HRAS1)
Ras proteins function as GDP/GTP-regulated binary switches in signal transduction cascades that can lead to cell growth, proliferation, differentiation, or survival. This protein undergoes a continuous cycle of de- and re-palmitoylation, which regulates its rapid exchange between the plasma membrane and the Golgi apparatus. This Ras superfamily has at least five major branches that include Ras, Rho, Ran, Arf/Sar, Rab. Ras itself has 3 primary isoforms (H-Ras, N-Ras, and K-Ras) that differ in their approximately 20 C-terminal amino acids. They are collectively referred to as Ras. In its active form, Ras is bound to GTP. This causes a conformational change that allow it to interact and bind to several effector molecules, most notably the members of the Raf family, the RalGDS family, and Phosphoinositide 3-kinases (PI3 Kinase). Ras then cleaves GTP to GDP resulting in its inactivation. In its oncogenic, mutated state, Ras is unable to hydrolyze GTP to GDP, thus staying in an active state and activating numerous pathways.

Suitable for use in Western Blot. Other applications not tested.

Recommended Dilution:
Western Blot: 1:2,000
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and store at -20C. Aliquots are stable for at least 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
