If I am using a human whole cell lysate, how much of each type of Arf is detected? Is there a paper showing the relative intensities of each Arf band in a Western? |
|||||||||
ANSWER: |
Thank you for your enquiry. Unfortunately we have not done testing to quantify the relative amounts of ARF isotypes from human whole cell lysate at this time. I apologize for any inconvenience this may cause you. I do have one article that specifically references this antibody in WB which may be of use. You may find it at the link below. http://jvi.asm.org/cgi/reprint/79/11/7207 I do wish that I had more information. I hope that this information helps and please don't hesitate to contact us for more advice or information. |

ab2806 supposes to detect 21kDa by Western Blot, but positive results using heart extract showing about 10kDa in your website. I want to know that reason. Also, I want to know whether this Ab can detect the single band of endogeneous expression. If so, please tell me the example. f.e, Hella cell 30ug. Finally, I want to ask whether this Ab will detect the single band even it detected Arf1,3,4,5 and 6. |

ANSWER: |
Thank you for your enquiry. After reviewing the data, the molecular weight markers on this data sheet appear to be incorrect. The band should be between the 14 KDa and 20 KDa, as indicated by Swiss Prot. There are many different forms of ARF and all forms can be modified on the N-Terminus. Depending on the species used and the form of ARF present, the molecular weights of the protein can vary from the mid teens, to the mid twenties. The image has been removed from this data sheet, whilst the originator of this product amends the information. If you have any further questions then please get back in contact with me.

Ab2806 immunoprecipitating ADP Ribosylation Factor from HeLa cells. 10ul of antibody were added to 500ul of HeLa cell lysate (at 1.5mg/ml) and incubated overnight before precipitation with Protein G. Negative control lysate received the same treatment except no antibody was added. ab2806 was used at 1/500 in the western blotting stage and the secondary antibody was an HRP conjugated anti-mouse IgG. The membrane was finally stained with amido black.

Overlay histogram showing HeLA cells stained with ab2806 (red line). The cells were fixed with 100% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab2806, 1/20 dilution) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (
