  • 製品の詳細

    Mouse monoclonal [AFP-01] to alpha 1 Fetoprotein

  • 由来種

    Mouse

  • 特異性

    The antibody reacts with human alpha-Fetoprotein (AFP), an oncofetal antigen of 70 kDa. AFP is a major fetal plasma protein, but is not present in healthy adult tissues. Elevated AFP concentrations in adult plasma may be an early marker of hepatocellular carcinoma or teratoblastoma, while high concentrations in amniotic fluid may indicate severe congenital defects of a fetus.

Incubate 60 min on ice. Centrifuge to remove cell debris. Mix lysate with non-reducing/reducing Laemmli SDS-PAGE sample buffer.

製品の特性

アプリケーション

Our Abpromise guarantee covers the use of ab3980 in the following tested applications.

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

アプリケーション Abreviews 特記事項
Sandwich ELISA Use at an assay dependent concentration.
ICC/IF Use a concentration of 5 µg/ml.
ELISA Use at an assay dependent concentration.
IP Use at an assay dependent concentration. Use at an assay dependant dilution. Interaction of the antibody with AFP is dependent on the presence of calcium ions (strongly inhibited by chelating agents). Such characteristics of the antibody can be exploited for immunoaffinity purification of APF under mild elution conditions.
WB Use at an assay dependent concentration. Detects a band of approximately 70 kDa.

ターゲット情報

  • 機能

    Binds copper, nickel, and fatty acids as well as, and bilirubin less well than, serum albumin. Only a small percentage (less than 2%) of the human AFP shows estrogen-binding properties.

  • 組織特異性

    Plasma. Synthesized by the fetal liver and yolk sac.

  • 配列類似性

    Belongs to the ALB/AFP/VDB family.
    Contains 3 albumin domains.

  • 発生段階

    Occurs in the plasma of fetuses more than 4 weeks old, reaches the highest levels during the 12th-16th week of gestation, and drops to trace amounts after birth. The serum level in adults is usually less than 40 ng/ml. AFP occurs also at high levels in the plasma and ascitic fluid of adults with hepatoma.

      ICC/IF image of ab3980 stained MCF7 cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab3980, 5µg/ml) overnight at +4°C. The secondary antibody (green)ÿwas Alexa Fluor® 488 goat anti-mouse IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

    Question

    We have been using your goat anti-human AFP antibody and I noticed on your website that it is no longer sold in the US. Do you offer a substitute or have a recommendation on what to use instead of ab8202-1?

    Read More
    Answer

    I am sorry for the inconvenience caused by this import restriction. While ab3980 is our only Anti-alpha 1 Fetoprotein raised in goat, we do offer a number of other Anti-alpha 1 Fetoprotein. We would recommend use of ab3980, Mouse monoclonal [AFP-01] to alpha 1 Fetoprotein as an alternative to the restricted antibody. Ab3980 has been tested in many of the same applications and has the same immunogen. This product also has been referenced in four publications.

    Question

    I am guessing I received a bad batch. In any case, we would like to use a different antibody to avoid further problems. I see that the Anti-alpha 1 Fetoprotein antibody [AFP-11] (ab3969) has been tested exactly in the application we need to use it. Could you send us this antibody? when could we expect to get it?

    Kind regards

    Question

    yIn a rush and the secondary antibody isAlexa Fluor 568 donkey anti - mouseIgG (invitrogen A10037) not the onei mentioned before. I used a red secondary
    I knowalexa 488 is green andalexa 568 is red andi used the right filter, let's just not keep on going on this point please. The filteri used was correct .
    Looking forward to you reply
    Best Wishes

    Answer

    ers used and secondary antibody are correct. We always double check the protocol steps with our customer when some of them do not make sense. I apologize for any inconvenience.

    This antibody has been tested in ICC/IF with MCF7 cells and is fully guaranteed; the product should have worked however we are unsure about the problem. In order to help you further I am happy providing free of charge replacement product or a different antibody. Could you let me know how you would like to proceed.

    Looking forward to hearing from you soon.

    Answer

    ram very sorry to hear that you are experiencing problems with this antibody.

    The protocol looks fine to me however I have following further suggestions

    - We used methanol as fixative when we characterized this antibody. We recommend trying this.
    - It is mentioned in the protocol that Alexa 488 conjugated secondary was used, Alexa 488 is green in colour however the images shows red staining which could mean that wrong filters were used for observing the images. Could you try using correct filters.

    I hope these suggestions will be helpful. Should you have any problem using this antibody again, please do not hesitate to contact me.
