Customer reviews and Q&As

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 th...

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 s...

Vielen Dank für Ihre Anfrage und Kooperation.


Leider hat mein Nachhacken ergeben, dass die Charge, die Sie erhalten haben, mit hCG alpha kontaminiert ist. Wir werden daher eine neue Charge erhalten, die ich natürlich, wenn Sie dies den m...

Vielen Dank fuer Ihre Email.

Ich habe Ihre Frage an das Labor weiteregeleitet, und diese wuerde sich gerne mal Ihr SDS-Page Gel ansehen.

Koennten Sie mir bitte ein Bild zukommen lassen?

Ich habe endlich eine Antwort von einem der Labore erhalten, die dieses Protein herstellen.
Ich vermute allerdings, sie wird Ihnen nicht gefallen:
"The glycosylation status is not checked for Catalog ab126653 hCG beta protein (Human). An SDS-...
