  • 常规说明

    Epitope tags provide a method to localize gene products in a variety of cell types, study the topology of proteins and protein complexes, identify associated proteins, and characterize newly identified, low abundance or poorly immunogenic proteins when protein specific antibodies are not available. Tagging with xxxDDDDK may be done at the N-terminus, N-terminus preceded by a methionine residue, C-terminus, and in internal positions of the target protein. The small size of the epitope tag and its high hydrophilicity tend to decrease the possibility of interference with protein expression, proteolytic maturation, antigenicity and function. The enterokinase cleavage site allows it to be completely removed from the purified fusion proteins.

    Affinity purified antibodies were coupled to agarose beads using a cyanogen bromide method.

    Question

    Hi,

    I am about to use these beads after pull down of the flag protein.

    https://www.abcam.com/DDDDK-tag-antibody-Agarose-ab1240.html

    I am washing them in RIPA and PBS and was wondering at which speed you recommend to centrifuge to pellet the beads. Is it fine using 14,000 g for 4 mins, or is it enough 30’’? I have just realised that as I am doing co-ip, 4 mins centrifugation may be too harsh on the protein complexes? I have used in the passed magnetic beads so I didn’t need to centrifuge.

    Answer

    Thank you for contacting us.

    If you are doing co-IP, it is not recommended to use RIPA buffer as it denaturing and may be too harsh on your protein complexes. I would suggest using a non-denaturing lysis buffer. For example:

    20 mM Tris HCl pH 8
    137 mM NaCl
    1% Nonidet P-40 (NP-40) (Triton X-100 can be substituted for NP-40)
    2 mM EDTA

    Store up to 6 months at 4°C. Immediately before use add protease inhibitors.

    As for your question regarding centrifugation, as shown on https://www.abcam.com/index.html?pageconfig=resource&rid=11385#d, section 4.2 "Method B", step 5, we suggest centrifuging at 1,000-3,000 g for 2 minutes at 4°C.

    I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

    Question

    I have now received the beads, and was wondering how much to add of the 50% slurry per immunoprecipitation.

    I have read on the label of the beads 100ug (therefore I assume the concentration of the antibody it will be 100ug/200ul gel which is 0.5ug/ul. If I use 20ul of beads gel +20 ul PBS per IP (50%slurry), then I will be using 10ug of antibody per IP (the protein comes from one 6-well plate for each IP). Isn’t this too much? The general protocol of Abcam says to add 70 to 100 ul of the slurry but that would be even more antibody.

    I used to use 2ug of IP antibody plus 100ug of protein for IP and worked always fine, so I am wondering if 10ug won’t be too much for one IP and will result in non specific binding?? I guess it is a bit different, because here I am pulling down directly with the anti-“flag” antibody, but would like to know how much antibody I should add to the IP.

    Thank you so much again for your help,

    Asked on Nov 08 2012

    Answer

    Thank you for your reply.

    I would recommend for the first time use of using a couple of different antibody concentrations and then seeing which one gives the best signal. You could have one condition where you use 2ug of antibody and another where you use 5ug of antibody.

    If there is anything else I can help you with, please let me know.

    Also, since you are based in the UK and I am based on the West coast of the USA, if you wish to receive faster replies, you could email mailto:technical@abcam.com and that will go to our UK team. I am more than happy to give any assistance, I just wanted to let you know why there is a delay in my response.

    Question

    Thank you very much for your prompt reply. So, if I understand correctly, these are pre-swollen beads ready to use?

    If I want to use a 50% slurry, does this mean that I should take 50ul of the beads (as they come in the tube), wash them a couple of times with PBS and then add 100 ul of PBS?

    I have always worked with magnetic beads so I am getting a bit confused!

    Thanks a lot again,

    Answer

    Thank you for your reply.

    This product are ready to use and the total volume of each vial you receive should be 400ul (200ul of gel and 200ul of buffer). Therefore to get a 50% slurry, you would have to use 100ul of product, wash in PBS and then resuspend in 50ul of PBS, that would give you 50ul of gel and 50ul of PBS.

    If there is anything else I can help you with, please let me know.

    Question

    I am going to use this product Anti-DDDDK tag antibody (Agarose) (ab1240) and I was wondering if you have any guidelines to use these beads, especially at which speed can I centrifuge them and for how long? How many times to wash the beads and which buffer to use for this purpose? Thanks a lot!

    Asked on Nov 01 2012

    Answer

    Thank you for contacting Abcam.

    You would use the product, ab1240 as you would use regular Protein A/G Sepharose beads, same type of buffers and centrifugation steps. I have attached the Abcam protocols booklet, which contains a general IP protocol that you would be able to use for guidance.

    If there is anything else I can help you with, please let me know.

    Vielen Dank für Ihren Anruf.

    Da es für Sie so dringend ist, habe ich im Labor angerufen, und man konnte mir tatsächlich prompt Auskunft geben:

    Die Konzentration beträgt 10 ug Antikoerper/200 ug "Slurry", das Volumen beträgt 400 ul.

    Verwenden Sie 15 bis 25 mcl pro 0.1-1.0 mg Proteinlysate.

    Ich hoffe, dies hilft Ihnen weiter.

    Question

    I'd like to do Immunoprecipitation by using ab1233 and ab1240. Is that including agarose bead and antibodies?

    Then, when I use that product, how could I do "pre-clear step"?
    It is my first time to do IP, and as I known "pre-clear"step is needed for reducing non-specific pull down.
    Please let me know if it is not necessary.

    Asked on Mar 06 2012

    Answer

    Thank you for your inquiry.


    Pre-clearing the lysates is always up to the end-user to determine because background levels will vary. Since both of these antibodies are conjugated to agarose, if you want to pre-clear the lysates you could use an isotype control.


    For your information, we do have a suitable isotype control for both ab1233 and ab1240 as a goat IgG Agarose conjugated antibody, ab104155.

    Also, here is our general IP protocol:

    Question

    Dear Sir/Madam,   I ordered two vials of anti  DDDDK antibody (agarose) from your company, we found that the amout of agarose beads in the first one is only half of the the second one, but they have the same lot number. So I think the first one has something wrong!!    Looking forward to hearing from you soon.

    Asked on Dec 16 2011

    Answer

    Thank you for contacting us. I am sorry to hear you have been experiencing problems with this anti-DDDDK tag antibody. Indeed, 100 µg of the affinity purified antibody is attached to the agarose gel and the total volume of each vial you received should be 400 microliters (200 microliters of gel and 200 microliters of buffer). I am sorry that you did nor receive this for one of the vials and for the inconvenience this has caused. Therefore, I have issued a free of charge replacement with the order number 1003302 which you should receive after the christmas holidays. To check the status of the order please contact our Customer Service team and reference this number. Please note that this free of charge replacement vial is also covered by our Abpromise guarantee. Should you still be experiencing difficulties, or if you have any further questions, please do not hesitate to let us know. I wish you the best of luck with your research.
