    Dissociation Constant: hCG: 1.4 x 10-4 and hCGbeta: 3.6 x 10-4
    Affinity Constant hCG: KA = 2.9 x 1010 1/M; KD = 3.4 x 10-11 M (= 0.03 nM)
    Affinity Constant hCGbeta: KA = 4.4 x 109 1/M; KD = 2.3 x 10-10 M (= 0.23 nM)

    The Life Science industry has been in the grips of a reproducibility crisis for a number of years. Abcam is leading the way in addressing the problem with our range of recombinant monoclonal antibodies and knockout edited cell lines for gold-standard validation.

    One factor contributing to the crisis is the use of antibodies that are not suitable. This can lead to misleading results and the use of incorrect data informing project assumptions and direction. To help address this challenge, we have introduced an application and species grid on our primary antibody datasheets to make it easy to simplify identification of the right antibody for your needs.

  • 相关性

    Human chorionic gonadotropin (hCG) is a glycoprotein hormone produced by trophoblastic cells of the placenta beginning 10 to 12 days after conception. Maintenance of the fetus in the first trimester of pregnancy requires the production of hCG, which binds to the corpus luteum of the ovary which is stimulated to produce progesterone which in turn maintains the secretory endometrium. hCG is present only in trace amounts in non pregnant urine and sera. It rises sharply during pregnancy. HCG is composed of two non identical, non covalently linked polypeptide chains designated as the a and b subunits. The a subunit of HCG is nearly identical to that of thyroid stimulating hormone (TSH), follicle stimulating hormone (FSH) and luteinizing hormone (LH). A germ cell tumor which is positive for cytokeratin, placental alkaline phosphatase (PLAP) and HCG but negative for EMA and AFP is probably a choriocarcinoma.

Question

Could you send the reference for specific binding between ab400 and ab126653 in general notes of antibody datasheet for me?
I am worried that it cannot bind together.

Asked on Feb 21 2013

Answer

The antibody ab400 was tested for specific binding to hCG, but not the hCG we supply as ab126653. There is no published journal reference for the testing of the antibody ab400, and I am fairly certain there is no commercial source of the hCG protein that was used for the testing. However, I am confident that ab400 will bind to ab126653.

Question

I would like to know whether ab400 can bind ab126653, yes or not ?

In the case of ab126653 cannot bind to ab400, please recommend other BhCG protein that can definitely bind to ab400 antibody.

The application used is SPR/ELISA.

Asked on Feb 20 2013

Answer

We have not tested the two products together, ab400 antibody and ab126653 protein, but we assume that ab126653 is almost identical, if not exactly identical, to the hCG beta that was used to determine the binding constants listed in the general notes section of the antibody datasheet.

Question

Many thanks for your email.

I need a monoclonal antibody anti-hCG, for direct ELISA. Preferably mouse and hCG-beta.

I've been using your antibody ab400 for indirect ELISA, and quite I'm happy with the results.
But at the moment, I need an antibody HRP labeled.

Just let me know whether do you have a product that may fit on my request.

Just one more thing for clarification:

With "mouse", do you mean it should be mouse monoclonal or against the species mouse?

Sorry for the delay.

Asked on Jul 04 2012

Answer

Thank you for contacting us.

Unfortunately, we do not sell this antibody in the conjugated form nor do we offer a conjugation service. However, we do have a conjugation kit available.

ab102891 EasyLink HRP Conjugation Kit (3 x 100µg HRP):
https://www.abcam.com/EasyLink-HRP-Conjugation-Kit-3-x-100g-HRP-ab102891.html https://www.abcam.com/EasyLink-HRP-Conjugation-Kit-3-x-100g-HRP-ab102891.html.

In addition, as the antibody contains sodium azide which interferes with this process and inhibits the HRP a purification step is necessary:

ab102783 Antibody Purification kit (1 purification)
https://www.abcam.com/Antibody-Purification-kit-1-purification-ab102783.html https://www.abcam.com/Antibody-Purification-kit-1-purification-ab102783.html.

Otherwise, if you let me know the target species and the application you want to move I can check our other antibodies for their suitability.


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