  • Function
    Acute phase-regulated receptor involved in clearance and endocytosis of hemoglobin/haptoglobin complexes by macrophages and may thereby protect tissues from free hemoglobin-mediated oxidative damage. May play a role in the uptake and recycling of iron, via endocytosis of hemoglobin/haptoglobin and subsequent breakdown of heme. Binds hemoglobin/haptoglobin complexes in a calcium-dependent and pH-dependent manner. Exhibits a higher affinity for complexes of hemoglobin and multimeric haptoglobin of HP*1F phenotype than for complexes of hemoglobin and dimeric haptoglobin of HP*1S phenotype. Induces a cascade of intracellular signals that involves tyrosine kinase-dependent calcium mobilization, inositol triphosphate production and secretion of IL6 and CSF1. Isoform 3 exhibits the higher capacity for ligand endocytosis and the more pronounced surface expression when expressed in cells.
    After shedding, the soluble form (sCD163) may play an anti-inflammatory role, and may be a valuable diagnostic parameter for monitoring macrophage activation in inflammatory conditions.
  • Tissue specificity
    Expressed in monocytes and mature macrophages such as Kupffer cells in the liver, red pulp macrophages in the spleen, cortical macrophages in the thymus, resident bone marrow macrophages and meningeal macrophages of the central nervous system. Expressed also in blood. Isoform 1 is the lowest abundant in the blood. Isoform 2 is the lowest abundant in the liver and the spleen. Isoform 3 is the predominant isoform detected in the blood.
  • Sequence similarities
    Contains 9 SRCR domains.
  • Domain
    The SRCR domain 3 mediates calcium-sensitive interaction with hemoglobin/haptoglobin complexes.
  • Post-translational
    A soluble form (sCD163) is produced by proteolytic shedding which can be induced by lipopolysaccharide, phorbol ester and Fc region of immunoglobulin gamma. This cleavage is dependent on protein kinase C and tyrosine kinases and can be blocked by protease inhibitors. The shedding is inhibited by the tissue inhibitor of metalloproteinase TIMP3, and thus probably induced by membrane-bound metalloproteinases ADAMs.
  • Cellular localization
    Secreted and Cell membrane. Isoform 1 and isoform 2 show a lower surface expression when expressed in cells.

IF by definition refers to any antibody application that utilizes fluorescence as the detection method. Thus, technically ICC and IF are one in the same, and you could argue that IHC is also a form of IF.

For the purposes of searching for products on our website, we distinguish those antibodies that have been tested in IHC with IHC followed by a letter designation (P-paraffin embedded sections, Fr-frozen sections, FoFr-formaldehyde fixed frozen sections). If an antibody has ICC or ICC/IF listed under tested applications they are the same thing and guaranteed to work in immunocytochemistry.

It sounds like you are performing IHC-P, immunohistochemistry on paraffin embedded sections; thus, all three antibodies that you identified, ab53003, ab8216, and ab111250 are tested and guaranteed to detect their respective targets via IHC-P in human samples. As stated in our AbPromise guarantee, we are happy to provide scientific support, replacement or refund should these products if they do not perform as indicated on the datasheet. More information on our Abpromise may be found at the following link:

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:



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.
