G-LISA Arf6 Activation Assay Biochem Kit (Colorimetric Based)
With the new Arf6 G-LISA® kit you can now measure Arf6 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 Arf6 G-LISA® kit contains an Arf-GTP-binding protein linked to the wells of a 96 well plate. Active, GTP-bound Arf6 in cell/tissue lysates will bind to the wells while inactive GDP-bound Arf6 is removed during washing steps. The bound active Arf6 is detected with a Arf6 specific antibody. The degree of Arf6 activation is determined by comparing readings from activated cell lysates versus non-activated cell lysates.
The kit contains sufficient reagents to perform 96 Arf6 activation assays. Since the Arf-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:
Figure 1. Arf6 activation measured by G-LISA. Lysates for Arf6 G-LISA were prepared from MDCK cells that were either attached to tissue culture plates (Activated) or kept in suspension for 2 hours (Control). 12.5, 6.25, and 3.1 µg of cell lysates were subjected to the G-LISA assay. Absorbance was read at 490 nm. Data are background subtracted.
