Effective Analysis of Active Ras

Why Use Ras G-LISA Activation Assay Kit (BK131)?


The Ras G-LISA® kit contains a Ras GTP-binding protein linked to the wells of a 96 well plate. Active, GTP-bound Ras in cell/tissue lysates will bind to the wells while inactive GDP-bound Ras is removed during washing steps. The bound active Ras is detected with a Ras specific antibody. The degree of Ras activation is determined by comparing readings from activated cell lysates versus non-activated cell lysates.


Product Uses for BK131 Include:

  • Ras signaling pathway studies
  • Ras activation assays with primary cells
  • Studies of Ras activators and inactivators
  • Ras activation assays with limited material
  • High throughput screens for Ras activation



Above: Ras activation by EGF measured by G-LISA™.  HeLa cells were serum starved (SS) for 24 h and treated with EGF (100 ng/ml for 2 min). 25, 12.5, 5, 1.25 µg of cell lysates were subjected to the G-LISA™ assay. Absorbance was read at 490 nm. Data are background subtracted

Effective_Ras_Analysis_with_Ras_G-LISA[TM]_Kits_4.gifVascular smooth muscle cells (VSMCs) oscillate between a differentiated (contractile) and a de-differentiated (synthetic) phenotype. In a recent study by Talwar et al., the group discovered that VSMCs, under selective ECM conditions, can also exist in a null state and can be driven towards the conventional differentiated or de-differentiated phenotypes in response to Rac and Rho signaling......



The small G-protein RhoA, functions as a molecular switch through interactions with GTP and GDP, to regulate an array of cellular processes including cell proliferation, cell shape, and cytoskeletal regulation. Seminal studies by Ridley and Hall showed that RhoA was activated by serum stimulation[1]; additionally, it is now appreciated that RhoA is a critical signaling mediator for some G protein-coupled receptors (GPCRs).
