Arf6 Pull-Down Activation Assay Kit


Cat. # 82401

Introduction

A. Background
ARF6 (ADP-ribosylation factor 6) is a member of the ARF super-family. ARF genes encode small GTPases that increase the ADP-ribosyltransferase activity of cholera toxin and are critical for vesicular trafficking as activators of phospholipase D. Arf6 regulates membrane trafficking and functions as a regulatory molecule of phagocytosis.
Currently there is no direct assay to measure the activation of Arf6 GTPase.
B. Assay Principle
The Arf6 Activation Assay Kit uses configuration-specific anti-Arf6-GTP Mouse monoclonal antibody to measure Arf6-GTP levels in cell extracts or in vitro GTPγS loading Arf6 activation assays. Anti-Arf6-GTP mouse monoclonal antibody is first incubated with cell lysates containing Arf6-GTP. Next, the GTP-bound Arf6 is pulled down by protein A/G agarose. Finally, the precipitated Arf6-GTP is detected through immunoblot analysis using Anti-Arf6 Rabbit Polyclonal Antibody.
The anti-Arf6-GTP monoclonal antibody can also be used to monitor the activation of Arf6 in cells and in tissues by immunohistochemistry.

Arf6 Activation Assay KitArf6 Activation Assay. Purified Arf6 proteins were immunoprecipitated after treated with GDP (lane 1) or GTPγS (lane 2). Immunoprecipitation was done with the anti-Arf6-GTP monoclonal antibody (Cat. No. 26918). Immunoblot was with an anti-Arf6 rabbit polyclonal antibody (Cat. No. 21032).

Assay Procedure

A. Reagent Preparation
1X Assay/Lysis Buffer: Mix the 5X Stock (Cat. # 30301) briefly and dilute to 1X in deionized water. Just prior to usage, add protease inhibitors such as 1 mM PMSF, 10 µg/mL leupeptin, or 10 µg/mL aprotinin.
B. Sample Preparation
Adherent Cells
1. Culture cells (one 10-cm plate, ~107 cells) to approximately 80-90% confluence. Stimulate the cells with activator or inhibitor as desired.
2. Aspirate the culture media and wash twice with ice-cold PBS.
3. Completely remove the final PBS wash and add ice-cold 1X Assay/Lysis Buffer (See Reagent Preparation) to the cells (0.5-1 mL per 10 cm tissue culture plate).
4. Place the culture plates on ice for 10-20 minutes.
5. Detach the cells from the plates by scraping with a cell scraper.
6. Transfer the lysates to appropriate size tubes and place on ice.
7. If nuclear lysis occurs, the cell lysates may become viscous and difficult to pipette. If this occurs, lysates can be passed through a 27½-gauge syringe needle 3-4 times to shear the genomic DNA.
8. Clear the lysates by centrifuging at 12,000 x g and 4°C for 10 minutes.
9. Collect the supernatant and store the sample (~1-2 mg of total protein) on ice for immediate use, or snap freeze and store at -70°C for future use.
Adherent Cells
1. Culture cells and stimulate with activator or inhibitor as desired.
2. Perform a cell count and then pellet the cells through centrifugation.
3. Aspirate the culture media and wash twice with ice-cold PBS.
4. Completely remove the final PBS wash and add ice-cold 1X Assay/Lysis Buffer (See Reagent Preparation) to the cell pellet (0.5-1 mL per 107 cells).
5. Lyse the cells by repeated pipetting.
6. Transfer the lysates to appropriate size tubes and place them on ice.
7. If nuclear lysis occurs, the cell lysates may become viscous and difficult to pipette. If this occurs, lysates can be passed through a 27½-gauge syringe needle 3-4 times to shear the genomic DNA.
8. Clear the lysates by centrifuging at 12,000 x g and 4°C for 10 minutes.
9. Collect the supernatant and store sample on ice for immediate use, or snap freeze and store at -70°C for future use.
C. In vitro GTPγS/GDP Protein for Positive and Negative controls
Note: In vivo stimulation of cells will activate approximately 10% of the available Arf6, whereas in vitro GTPγS protein loading will activate nearly 90% of Arf6.
1. Aliquot 0.5 mL of cell extract (or 1 µg of purified Arf6 protein) into two microcentrifuge tubes.
2. To each tube, add 20 µL of 0.5 M EDTA (final concentration of 20 mM).
3. Positive control: add 5 µL of 100 X GTPγS (Cat. # 30302) to the 1st tube
4. Negative control: add 5 µL of 100 X GDP (Cat. # 30304) to the 2nd tube.
5. Incubate both tubes at 30°C for 30 minutes with agitation.
6. Stop loading by placing the tubes on ice and adding 32.5 µL of 1 M MgCl2 (final concentration of 60 mM).
D. Affinity Precipitation of Activated G Protein
1. Aliquot 0.5-1 mL of cell lysates (about 1 mg of total cellular protein) to a microcentrifuge tube.
2. Adjust the volume to 1 mL with 1X Assay/Lysis Buffer (See Reagent Preparation).
3. Add 1 µL anti-Arf6-GTP antibody (Cat. # 26918).
4. Prepare the protein A/G Agarose bead slurry (Cat. # 30301) by resuspending through vertexing or titrating.
5. Quickly add 20 µL of resuspended bead slurry to above tube.
6. Incubate the tube at 4°C for 1 hour with gentle agitation.
7. Pellet the beads through centrifugation at 5,000 x g for 1 min.
8. Aspirate and discard the supernatant (making sure not to disturb or remove the bead pellet.
9. Wash the beads 3 times with 0.5 mL of 1X Assay/Lysis Buffer, centrifuging and aspirating each time.
10. After the third wash, pellet the beads through centrifugation and carefully remove all the supernatant.
11. Resuspend the bead pellet in 20 µL of 2X reducing SDS- PAGE sample buffer.
12. Boil the sample for 5 minutes.
13. Centrifuge it at 5,000 x g for 10 seconds.
E. Western Blot Analysis
1. Load 15 µL/well of pull-down supernatant to a polyacrylamide gel (17%). It is recommended to include a pre-stained MW standard (as an indicator of a successful transfer in step 3 below).
2. Perform SDS-PAGE following the manufacturer’s instructions.
3. Transfer the gel proteins to a PVDF or nitrocellulose membrane following the manufacturer’s instructions.
Note: Steps 4-11 are at room temperature with agitation
4. Following electroblotting, immerse the PVDF membrane in 100% Methanol for 15 seconds, and then allow it to dry at room temperature for 5 minutes.
Note: If Nitrocellulose is used instead of PVDF, step 4 Should be skipped.
5. Block the membrane with 5% non-fat dry milk or 3% BSA in TBST for 1 hr at room temperature with constant agitation.
6. Wash the blotted membrane three times with TBST, 5 minutes each time.
7. Incubate the membrane with Anti-Arf6 Rabbit Polyclonal Antibody (Cat. # 21032), which is freshly diluted 1: 50~500 (depending on the amount of Arf6 proteins in your sample) in 5% non-fat dry milk or 3% BSA in TBST, for 1-2 hr at room temperature with constant agitation or at 4°C overnight.
8. Wash the blotted membrane three times with TBST, 5 minutes each time.
9. Incubate the membrane with a secondary antibody (Cat. # 29002), which is freshly diluted 1: 1000 in 5% non-fat dry milk or 3% BSA in TBST, for 1 hr at room temperature with constant agitation.
10. Wash the blotted membrane three times with TBST, 5 minutes each time.
11. Use the detection method of your choice such as ECL.
