应用

Our Abpromise guarantee covers the use of ab977 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

应用 Ab评论 说明
IP Use at an assay dependent dilution.
WB 1/1000 - 1/5000. Incubate for 1 hour at room temperature. Background can be reduced by adding NaCl up to a concentration of 1.5M.
ICC/IF 1/1000. Incubate for 1 hour at room temperature.

靶标

  • 相关性
    The E2Tag is a peptide which is derived from the Bovine Pappillomavirus type-1 transactivator protein E2 and consists of 10 amino acids(SSTSSDFRDR). The detection of E2-tagged proteins is based on the binding of mouse monoclonal antibodies specific to the tagged recombinant protein.

    Cos-7 cell lysates (1µg of total protein per lane) were transfected with pQM vectors encoding two different E2-tagged proteins. Detection is performed with anti-E2Tag antibody (5E11) (1:10 000 in TBST) with and without high salt followed by incubation with goat anti-mouse HRP conjugate (1:10,000).

    ab977 at 1/200 dilution staining human Hela cells by ICC/IF. The HeLa cells were transfected with the fusion DNA construct pQM-NTag/A consisting of E2 tag fused in frame with gene specific cDNA. The cells were fixed with paraformaldehyde and blocked with serum prior to incubation with the antibody for 2 hours. A Cy3 conjugated sheep anti-mouse IgG antibody was used as the secondary.

Question

the vial our customer got as a replacement contains only 40 µl, not 100 µ of the antibody #AB977l. What now?

The anti-E2 antibody lot # 9057 does not or only insufficiently detect the transiently in COS7, Alexander, Hep3B and HEK 293 cells expressed fusionprotein E2-p14.5 by westernblotting This same fusionprotein is detected on the same membrane by the same antibody ordered 6 month before Lot # 6260. SAMPLE HEK 293, COS7, Alexander, Hep3B Mammalian cells PRIMARY ANTIBODY Primary Antibody Details (Dilutions, Diluting Buffer) 1.AB over night 4?C or 2hrs RT, 3x10min PBS wash SECONDARY ANTIBODY 2.AB anti mouse (Biorad) 1:3000 1hr RT 3x10 min PBS wash, DETECTION METHOD chemiluminescence by ECL POSITIVE AND NEGATIVE CONTROLS USED old Lot #6260 of the same antibody ANTIBODY STORAGE CONDITIONS The vial was always kept ? 20 C? and never touched or opened before Nov .04.

Answer

I'm very sorry to hear you are having problems with ab977 lot 9057; we have not had any reported problems with this lot, it is possible the antibody has gone off when it was sent to you. I will arrange for a new vial to be sent to you as soon as possible with your shipment. We are currently out of stock of this antibody but should have some more in the next few days, my apologies for the delay. I would be very grateful if you could let me know if you are satisfied with the new lot. Thank you for your patience,

Question

Is one of your anti-E2 tag antibodies better than the other for immunoprecipitation? How much have you used for immunoprecipitation experiments? Is one more sensitive for western blotting? If one is better for blotting and the other for immunoprecipitation, can you indicate anything about the magnitudes of the differences? Sincerely yours, John Dougherty

Answer

For immunoprecipitation and for affinity chromatography we recommend to use ab978 - during further elution milder conditions can be used. We have used ab978 beads for affinity purification of several different proteins in small quantities. For western blot it is better to use ab977 as this clone has higher affinity than ab978.
