Ras (p21), a signal transducer, was first characterized as the transforming genes of Harvey & Kristen sarcoma virus (1). The Ras family (H-Ras, N-Ras, and K-Ras) regulates cell growth, differentiation and apoptosis (2). Switching from an active or resting state, Ras can either bind GTP or GDP respectively. In the triphosphate conformation, Ras will interact with GTPase activating protein (GAP) to increase its activity (3). Mutations in any of the three isoforms can convert these proteins into active oncogenes. Additionally, Ras mutations are found in 30% of all human cancer (4).
Suitable for use in Flow Cytometry, Western Blot and Immunoprecipitation. Other applications not tested.
Flow Cytometry: 1:100
Western Blot: 1:1000-1:10,00
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. 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.
