Ras G-LISA Activation Assay Kit (Colorimetric Based) - 96 assays

G-LISA Ras Activation Assay Biochem Kit (Colorimetric format)

Product Uses 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


With the new Ras G-LISA™ kit you can now measure Ras activation from cell and tissue samples in less than 3 h.  G-LISA™ requires only 1-5% of the material needed for a conventional pull-down assay.  You will also be able to handle large sample numbers and generate quantitative results.  For a more detailed introduction on G-LISA™ assays and a listing of other available G-LISA™ kits, see our main G-LISA™ page.

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.  Inactivation of Ras is generally achieved in tissue culture by a serum starvation step (see kit datasheet for more information).  

Kit contents

The kit contains sufficient reagents to perform 96 Ras activation assays. Since the Ras-GTP affinity wells are supplied as strips and the strips can be broken into smaller pieces, each kit can be used for anywhere from one to multiple assays. The following components are included in the kit: 

  1. 96 Ras-GTP affinity wells (divisible into 12 strips of 8 wells each)
  2. Lysis buffer
  3. Binding buffer
  4. Antigen presenting buffer
  5. Wash buffer
  6. Antibody dilution buffer
  7. Anti-Ras antibody
  8. HRP-labeled secondary antibody
  9. Positive control Ras protein
  10. Protease inhibitor cocktail (Cat. # PIC02)
  11. Absorbance detection reagents
  12. Precision Red™ Advanced protein assay reagent (Cat. # ADV02)
  13. Manual with detailed protocols and extensive troubleshooting guide

    Equipment needed

  14. 96-well plate spectrophotometer capable of reading 490 nm wavelength
  15. Multichannel or multidispensing pipettor
  16. Orbital microplate shaker capable of at least 200 rpm shaking (400 rpm is optimal)

Example results


Figure 1.  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
