Our Abpromise guarantee covers the use of ab24607 in the following tested applications.

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

Application Abreviews Notes
WB 1/500. Detects a band of approximately 34 kDa (predicted molecular weight: 38 kDa).


  • Relevance
    Cre-recombinase is a 38 kDa DNA recombinase derived from the P1 bacteriophage. It is highly specific for a 34 bp DNA sequence (loxP) found in P1 DNA. It catalyzes site-specific recombination between two 34-base-pair LOXP sites. Its role is to maintain the phage genome as a monomeric unit-copy plasmid in the lysogenic state. It is homotetramer when bound to DNA and belongs to the "phage" integrase family.

Ante todo quisiera desearle un muy Feliz Año.

Muchas gracias por tomarte la molestia de rellenar el cuestionario y mandar más imágenes.

Hay alguna sugerencia que posiblemente mejore la tinción obtenida. Me decías en el primer correo que se había probado ya la recuperación antigénica del tejido tras fijación con 4%PFA durante la noche. Es posible que fijando las secciones congeladas con acetona a temperatura ambiente durante 10 minutos se observe mayor tinción. Además, la acetona tiene efecto permeabilizador en las células, facilitando la inclusión del anticuerpo en las mismas.

Otra recomendación que quisiera hacer es probar de bloquear el tejido de forma más suave. Se está utilizando un porcentaje muy alto de suero (16%), y los anticuerpos además se diluyen en el mismo.

Si podéis usar una dilución menos concentrada (10%) y diluir los anticuerpos en TBST con un porcentaje bajo (1%) de BSA, quizás la membrana no quede tan bloqueada y se permita una mejor visualización de la tinción.

En cualquier caso, si preferís que apliquemos directamente la garantía, puesto que ya habíais realizado pasos de optimización, y que os mandemos un reemplazo del anticuerpo (del mismo u otro diferente) o reembolso del importe del mismo, no dudes en indicármelo y estaré encantada de poder ayudar.

Espero entonces tu respuesta para proceder y quedo a la disposición de cualquier otra consulta que podáis tener.

Vielen Dank für diese zusätzliche Information.

Leider haben wir keinen Antikörper den ich für die Detektion Ihres rekombinanten Proteins garantieren kann. Ich habe drei Antikörper gefunden die vielleicht für Sie in Frage kommen und die Sie sich genauer anschauen sollten.

1. https://www.abcam.com/cre-recombinase-antibody-723-ab24607.html

Immunogensequenz ist das gesamte native Cre Rekombinase Protein. Die Sequenz sollte daher mit der Sequenz in dem rekombinanten Protein übereinstimmen.

2. https://www.abcam.com/cre-recombinase-antibody-ab137240.html

Bei dem Immunogen handelt es sich um ein rekombinantes full length protein des Bacteriophage P1 Cre recombinase.

3. https://www.abcam.com/progesterone-receptor-antibody-alpha-pr6-ab2765.html

Die Immunogensequenz dieses Antikörpers ist leider nicht näher bestimmt. Der Antikörper wurde gegen das gesamte Hühnchen Progesteron gerichtet hergestellt. Die Hühnchensequenz verglichen mit der zur Verfügung gestellten Progesteronsequenz des rekombinanten Proteins weißt eine Uebereinstimmung von 78% auf. Die Detektion eines Proteins werten wir als wahrscheinlich, wenn eine Übereinstimmung von etwa 85% besteht.

Der ab24607 ist unter diesen drei Möglichkeiten der mit den meisten Referenzen und eingereichten Abreviews und daher am besten charakterisiert. Ab24607 wurde schon für IHC-Fr in Maus verwendet und zwei Abreviews speziell hierfür wurden verfasst.

Ich hoffe ich konnte Ihnen etwas weiter helfen. Es tut mir Leid dass ich Ihnen in diesem Fall kein perfektes Produkt anbieten kann.

Sollten Sie sich dafür entscheiden einen dieser Antikörper zu kaufen, möchte ich Sie noch auf unsere RabMab Aktion aufmerksam machen. Bitte lesen Sie mehr über diese Aktionhttps://www.abcam.com/index.html?pageconfig=resource&rid=15447.

Bitte zögern Sie nicht sich wieder bei mir zu melden, sollten Sie weitere Fragen oder Probleme mit unseren Produkten haben.

For UNTESTED species and/or applications, we have established a testing discount program. Here is a brief description of how it works:

The testing discount program is for customers who like to use an antibody/protein/kit on an untested species/application. You would purchase the antibody/protein/kit at full price, test it and submit an Abreview with your data (positive or negative). On your next order you will receive a discount for ONE antibody/protein at the full price (100%) of the antibody/protein you have tested, or a full price discount for the amount paid for the kit. The terms and conditions applicable to this offer can be found here: https://www.abcam.com/collaborationdiscount.
