靶标

  • 功能

    Transcription factor that binds to the octamer motif (5'-ATTTGCAT-3'). Forms a trimeric complex with SOX2 on DNA and controls the expression of a number of genes involved in embryonic development such as YES1, FGF4, UTF1 and ZFP206. Critical for early embryogenesis and for embryonic stem cell pluripotency.

  • 组织特异性

    Expressed in developing brain. Highest levels found in specific cell layers of the cortex, the olfactory bulb, the hippocampus and the cerebellum. Low levels of expression in adult tissues.

  • 序列相似性

    Belongs to the POU transcription factor family. Class-5 subfamily.
    Contains 1 homeobox DNA-binding domain.
    Contains 1 POU-specific domain.

  • 发展阶段

    Highly expressed in undifferentiated embryonic stem cells and expression decreases gradually after embryoid body (EB) formation.

  • 结构域

    The POU-specific domain mediates interaction with PKM2.

  • 翻译后修饰

    Sumoylation enhances the protein stability, DNA binding and transactivation activity. Sumoylation is required for enhanced YES1 expression.
    Ubiquitinated; undergoes 'Lys-63'-linked polyubiquitination by WWP2 leading to proteasomal degradation.

    Question

    Dear Sir / Madam,
    One of the biggest customer in stem cell lab would like to have an
    antibody that is specific against Oct 4, either variant A or variant B
    to distinguish between them. In literature, oct 4 antibodies are not
    able to bind to specific variants.
    What do you recommend?
    Many Thanks and Best Regards,

    Read More
    Answer

    Thank you for your enquiry and your interest.

    I can confirm that two isoforms of Oct 4 have been identified, and the exact amino acid sequences (aa) can be found at this website: http://www.uniprot.org/uniprot/Q01860

    - Isoform A: Q01860-1 (1-360 aa)

    - Isoform B: Q01860-2 (1-265 aa)

    ab109183 - this antibody was raised against a peptide corresponding to the region between 265-360 aa, soit is very likely to recognize Isoform A.

    ab18976 - the immunogen selected was around region 1-14 aa, thus it would recognize potentially both Isofm A and B.

    If you need any further assistance in the future, please do not hesitate to contact me.

    Question

    Hola ,
    ¿Qué tal? estoy interesada en inmunofluorescencia
    de doble marcaje en tejidos humanos parafinados.
    En concreto me interesarían los anticuerpos primarios, a ser posible
    monoclonales, de distintas especies para poder combinarlos, contra las
    siguientes proteínas humanas:
    * OCT4: ab18976, ab109183, ab129030
    * tenascin C: ab6346, ab3970, ab108930, ab86182
    * CD68: ab955, ab845, ab125047
    * S100A6: ab11181, ab117714, ab75676
    * ganglioside GD2: ab68456
    * Sox10: ab107532, ab122977
    * MMP9: ab76003, ab119906
    * CD163: ab111250, ab100909
    * PNMT: ab119784
    He indicado los productos que me parecían interesantes de la web, pero
    acepto sugerencias.
    Y tambíen estaría interesada en los anticuerpos secundarios marcados
    con distintos fluorocromos para anticuerpos de distintas especies.
    Necesitaría la ficha técnica y el precio de cada uno de ellos.
    Muchas gracias.
    Saludos,

    Answer

    Muchas gracias por tu respuesta.

    Es importante que todos los anticuerpos que escojas para llevar a cabo IHC-P en tejido humano estén validados (y por tanto garantizados por Abcam) para funcionar en esta especie y aplicación. Esta información aparece en la hoja técnica de los productos.

    También es importante echar un vistazo a las hojas de datos de cada uno de los productos para tener en cuenta recomendaciones especificas, tales como diluciones, métodos de recuperación antigénica, y demás que pueden aparecer en ellas. A las fichas técnicas se puede acceder desde la página web, escribiendo el código del anticuerpo (ab955, por ejemplo) en la casilla azul en la parte de arriba de nuestra página web (https://www.abcam.com/).

    Desconozco las combinaciones que queréis llevar a cabo mediante inmunofluorescencia doble con los anticuerpos mencionados. En general, a la hora de hacer inmunoensayos múltiples hay que tener mucha precaución para evitar reactividad cruzada. Es importante usar anticuerpos procedentes de distintas especies si se puede, o al menos con diferentes isotipos. Una buena forma de evitar reactividad cruzada es usando secundarios de la misma especie. Además esto permite usar suero de dicha especie para bloquear.

    Te copio los links a los protocolos que tenemos en nuestra web para llevar a cabo doble inmunofluorescencia por s pudieran resultar de ayuda:

    https://www.abcam.com/index.html?pageconfig=resource&rid=11459

    https://www.abcam.com/index.html?pageconfig=resource&rid=11458

    De todas maneras si quieres que comentemos distintas posibilidades y escenarios posibles, no dudes en contactarme otra vez.

    Respecto a los secundarios, tenemos muchos anticuerpos que podrían serviros. Te aconsejo que en función de los primarios y combinaciones que vayáis a llevar a cabo, optéis por uno u otro. Para llevar a cabo la búsqueda de los secundarios desde la pagina web (https://www.abcam.com/) pincha en la pestaña “Secondary Antibodies”. Se abre una nueva ventana de “Advance Search”, en la cual se pueden elegir las categorías requeridas. La única categoría obligatoria es el isotipo del anticuerpo, pues tiene que coincidir con el del primario. El resto de categorías son opcionales, pero son muy útiles para afinar la búsqueda y elegir el anticuerpo más apropiado según la especie del primario, la conjugación deseada, la clonalidad, la aplicación en la que se va a testar, etc…

    Los precios y la disponibilidad pueden consultarse igualmente en la parte superior de la datasheet de los productos. Si necesitas un presupuesto no dudes en hacérmelo saber para que te lo envíe. Además tenemos algún descuento para pedidos superiores a 5 productos, por lo que si vais a realizar un pedido de estas características te animaría a que nos contactaras primero.

    Espero que esta información sea de ayuda. Como te digo, para cualquier aclaración o más sugerencias, estaré encantada de echar una mano.

    Thank you for contacting Abcam about this. I have changed the datasheet to remedy the error that you have noticed. Ab109183 Anti-Oct4 antibody [EPR2054] is a rabbit IgG isotype. When using in Western Blot I would recommend using one of the following secondary antibodies: ab97051: Goat polyclonal Secondary Antibody to Rabbit IgG - H&L (HRP) https://www.abcam.com/Goat-polyclonal-Secondary-Antibody-to-Rabbit-IgG-H-L-HRP-ab97051.html or ab97064: Donkey polyclonal Secondary Antibody to Rabbit IgG - H&L (HRP) https://www.abcam.com/Donkey-polyclonal-Secondary-Antibody-to-Rabbit-IgG-H-L-HRP-ab97064.html These products are covered by our Abpromise guarantee.
