    Epitope tags are short peptide sequences that are easily recognized by tag-specific antibodies. Due to their small size, epitope tags do not affect the tagged protein’s biochemical properties. Most often sequences encoding the epitope tag are included with target DNA at the time of cloning to produce fusion proteins containing the epitope tag sequence. This allows anti-epitope tag antibodies to serve as universal detection reagents for any tag containing protein produced by recombinant means. This means that anti-epitope tag antibodies are a useful alternative to generating specific antibodies to identify, immunoprecipitate or immunoaffinity purify a recombinant protein. The anti-epitope tag antibody is usually functional in a variety of antibody-dependent experimental procedures. Expression vectors producing epitope tag fusion proteins are available for a variety of host expression systems including bacteria, yeast, insect and mammalian cells.

A replacement vial is being sent to you and you should receive it tomorrow. For your record it is order# 39089. I did receive some information from the antibody's originator which I hope will also help you out concerning cell fixation. "We have found that the context adjacent to the c-myc epitope can interfere with its detection in some applications. This is particularly true with immunocytochemistry involving aldehyde-fixed tissues, in which the antibody must recognize the aldehyde-fixed epitope in the native conformation. In some cases, the K in the epitope also becomes modified by the aldehyde, abrogating antibody recognition. In these cases, it is best to fix with something that does NOT modify lysines and denatures the protein. I would recommend using either acetone:acetic acid (95%:5% at dry ice temperatures). Just wash the cells briefly with serum-free balanced salt solution for a couple of seconds at 37C (with gentle agitation), and then plunge the slide into the acetone:acetic acid for about 10 seconds. Air-dry the slide after this. Of course, this fixative is not compatible with tissue culture plastic, so the cells need to be grown on poly-lysine coated glass, or something that can resist the acetone." Please let me know how the replacemnet vial works out.

Thank you for your patience. I was away on vacation and could not get back to you earlier. We have had no other complaints regarding this antibody. You're getting absolutely no signal? Are you doing antigen retrieval? You stated that your cells are fixed with 4% paraformaldehyde and that may be modifying the epitope that the antibody recognizes. At this point that is my suggestion as well as trying a higher concentration of the antibody. Let me know what you think.

I think that my purchasing agent was not clear. The antibody has not worked for me yet, but my current complaint is that Federal Express did not handle the shipping properly. It was shipped by you Fed Ex overnight but sat at Fed Ex for an additional day. While I presume that the Ab should be stable, I have no idea how it sat at Fed Ex. In the meantime: Description of the problem: (no signal, high background, non-specific signal etc). No signal Sample (Species/Cell extract/Nuclear extract/Purified protein/ Recombinant protein etc): Fixed MDCK cells Sample preparation: Fixed with 4% paraformaldehyde, permeabilized with 0.5% Triton X100, blocked with fish skin gelatin Blocking Conditions (Buffer/Time period, Blocking agent etc) See above Primary Antibody (Manufacturer/Species/Diluent/Dilution/ Incubation time, Wash step) YOUR Ab, at recommended 1:250 dilution in PBS- with fish skin gelatin and saponin Secondary Antibody (Manufacturer/Species/Diluent/Dilution/ Incubation time, Wash step) Molecular Probes, goat anti chicken 546, 1:100 Detection method Immunofluorescence Positive and negative controls used. (Please specify) Positive control: same cells, with expression induced under the same conditions, good signal with 9E10. Negative control: same cells, expression repressed Optimization attempts (problem solving) Have you run a No primary control? I usually do this when I have too much background, not no signal How many times have you tried this assay? Once-I will try it again but wanted to raise the concern re Ab sitting at Fed Ex.

I looked at the tracking for Fed Ex and it states that the package was delivered on Feb 25 at 11am and signed for by L. Kim. Although the antibody arrived a day late, it should not affect the antibody (it should have still been cold). If you continue to experience problems with this antibody, please contact me again.

We don't have an unlabeled goat anti-chicken IgY antibody (all of ours are conjugated). Aves lab has one: Cat.# U-1010. If you have any more questions, please contact us again.

I contacted the supplier of ab172, and they provided me with the following information. Chicken IgY's lack an Fc domain in the "nu" heavy chain which where proteins A and G normally bind. Consequently, protein A/G-Agarose cannot be used directly to immunoprecipitate chicken IgY's as they can mammalian IgG's. There are, however, three approaches that one can get around this limitation (the first method is detailed below): — First, one can include an extra step between chicken IgY binding to antigen and addition of protein G-Sepharose. In this step, you simply incubate the chicken IgY/antigen complex with goat anti-chicken IgY. In this way, the protein G-Agarose immunoprecipitates the goat antibody bound to the chicken antibody bound to the antigen. — Second, one can substitute "anti-chicken IgY, immobilized" (Promega Cat.#G1191, Price=$110 for 1.0 ml on pg.304 in the 1998 Promega Catalog) for protein G-Agarose. This product is a goat anti-chicken IgY antibody conjugated to agarose bead. — Third, one can conjugate your affinity-purified chicken antibodies directly to Agarose. This can be accomplished using CarboLink kit from Pierce (Cat.#44900). Solutions — Lysis buffer -- 10 mM Tris buffer (pH 8.0), 150 mM NaCl, 0.02% sodium azide, 1.0% Triton X-100, 1.0% sodium deoxycholate, 1.0% bovine hemoglobin, 1.0 mM iodoacetamide (prepared fresh), 15 ug/ml aprotinin (prepared fresh), 1.0 mM phenylmethylsulfonyl fluoride (PMSF) (prepared fresh). — Washing buffer A -- 10 mM Tris buffer (pH 8.0), 150 mM NaCl, 0.02% sodium azide, 0.1% Triton X-100, 0.1% bovine hemoglobin. — Washing buffer B -- 10 mM Tris buffer (pH 8.0), 150 mM NaCl, 0.02% sodium azide. — Washing buffer C -- 50 mM Tris buffer (pH 6.8) — Laemmli buffer for SDS-PAG electrophoresis Other Reagents — Unlabeled goat anti-chicken IgY — protein G-Agarose (Boehringer-Mannheim Cat.#1 719 416) Steps: 1. Lyse your 35S-labeled cells using Lysis Buffer (4C). Centrifuge the lysate at 3000 g for 15 minutes at 4C to pellet nuclei 2. Transfer the supernatant to a set of microfuge tubes and centrifuge at 10,000 g for 40 minutes to remove membranous debris. Be sure to use a refrigerated microfuge for this step, since microfuges at room temperature can get overly warm with such prolonged use. 3. Transfer the supernatant to another set of microfuge tubes and add a slurry of Protein G-Agarose to the tube. The concentration of Protein G-Agarose to be added at this step should be equivalent to that used in step # 7 below, which in turn, is based on the concentration of chicken antibodies added in step #5 below. Incubate the Protein G-Agarose slurry mixture for 2 hours at 4C with gentle agitation. 4. Centrifuge the Protein G-Agarose slurry mixture for 5 minutes at 1000 g at 4C. This removes any cellular proteins that have a natural tendency to bind Protein G-Agarose. 5. Transfer the supernantant another set of microfuge tubes. Add your affinity-purified chicken antibody to the homogenate,and incubate on ice overnight. [The amount of antibody to be added needs to be determined empirically, but is usually the same concentration as is used in enhanced chemiluminescent westerns]. 6. Add unlabeled goat anti-chicken IgY, and incubate on ice for 2 hours. [The amount of goat anti-chicken antibody should be in 2-5 fold excess over the concentration of chicken antibody, in order to assure that all of the chicken antibody-antigen complex is precipitated in subsequent steps.] 7. Add protein G-Sepharose slurry to the homogenate, and incubate 2 hours with gentle agitation in a cold room. [The amount of protein G-Sepharose added should match the molar concentration of goat anti-chicken IgG in the mixture. That is, if 1.0 ml of the protein G-Sepharose has a capacity to bind 100 femtomoles of goat antibody, and if the homogenization mixture contains a total of 200 femtomoles of goat antibody, then add 2.0 mls of the protein G-Sepharose slurry.] 8. Centifuge the slurry at 1000 g for 5 minutes at 4C. Discard the supernatant. Resuspend the slurry in Washing Buffer A. 9. Repeat step 8. 10. Centrifuge the slurry at 1000 g for 5 minutes at 4C. Discard the supernatant. Resuspend the slurry in Washing Buffer B. 11. Repeat step 10. 12. Centrifuge the slurry at 1000 g for 5 minutes at 4C. Discard the supernatant. Resuspend the slurry in Washing Buffer C. 13. Remove all but a tiny volume of supernatant (<50 ul) over the agarose pellet. 14. Add Laemmli buffer. Incubate at 100C for 5 minutes. Centrifuge the slurry for 5 minutes. 15. Finally, load the supernatant onto an SDS-gel, subject the gel to electrophoresis, transfer the proteins onto a suitable membrane, and expose the membrane to an X-ray film to detect radioactive bands. Note: If you notice high backgrounds, substitute Lysis Buffer for Washing Buffer A in steps 8 and 9, above. I apologize with the delay in answering your question, and hope this information is helpful. If you have any more questions, please contact us again.

I'm afraid that I don't know of anyone who has used the c-myc antibodies for immunofluorescence in yeast, either. Sorry.
