  • 機能
    Could play a role in phagocytic activities of tissue macrophages, both in intracellular lysosomal metabolism and extracellular cell-cell and cell-pathogen interactions. Binds to tissue- and organ-specific lectins or selectins, allowing homing of macrophage subsets to particular sites. Rapid recirculation of CD68 from endosomes and lysosomes to the plasma membrane may allow macrophages to crawl over selectin-bearing substrates or other cells.
  • 組織特異性
    Highly expressed by blood monocytes and tissue macrophages. Also expressed in lymphocytes, fibroblasts and endothelial cells. Expressed in many tumor cell lines which could allow them to attach to selectins on vascular endothelium, facilitating their dissemination to secondary sites.
  • 配列類似性
    Belongs to the LAMP family.

Thank you for your enquiry.

I can confirm that the immunogen used for CD68 antibody [KP1] (ab955) is lysosomal fraction of human lung macrophages.

I am sorry this has not been specifically epitope mapped and we have no further information on this occasion.

I hope this will be helpful to you. If you have any further questions, please do not hesitate to contact us.

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.

Thank you for contacting us.

Effectively all of the products mentioned are suitable, and therefore are guaranteed for IHC in frozen sections in the species stated on their datasheets.

However, instead of using PFA as a fixative, I would better suggest using acetone, methanol or ethanol at -20°C for 30 min, so the additional antigen retrieval step can be skipped. If, by the tissue’s nature PFA is required as a fixative, antigen retrieval is recommended to allow the antibody reach the epitope.

All of our products are covered by our Abpromise® guarantee, which ensures that you can trust them, and they should work in the tested species and applications stated on the datasheet, or we will offer a replacement, credit, or refund, if reported within 6 months of purchase.

Thank you for taking time to complete our questionnaire. I am sorry to hear that this antibody is not providing satisfactory results. The details provided will enable us to investigate this case and will provide us with vital information for monitoring product quality.

Having reviewed this case, I would like to offer some suggestions to help optimize the results from ab955 since this antibody has been tested in mouse paraffin-embedded tissue sections.

For the fixation, we generally recommend between 18 - 24 hrs. It may be just that your sections are underfixed.

For antigen retrieval, was this performed in the microwave? We generally recommend 20 mins, but it's best to optimize between 15 - 30 mins. When the 20 mins has elapsed, you can run cold tap water into the vessel for 10 mins.

If you want to permeablize the sections, you should do a 0.1% Triton-X 100 in PBS treatment as a separate step and omit the Triton X-100 from the blocking buffer.

For blocking, have you tried5-10% normal goat serum instead of BSA? You should also put this in PBS.

The most important thing to try wouldbe to test a1/100 dilution of ab955 overnight at 4C instead of 1/200 for 1 hr RT. You should do this incubation in 1% BSA in PBS.

For the s100 antibody ab8330, would you be able to run a positive control with rat tissues since this antibody isn't tested in mouse?

For the CD31 antibody, ab7388, we know that this does not work well with PFA fixation (see Abreview linkedbelow). We have heard that it works wellwhen used on frozen sections of mouse skin that werefixed in methanol:acetone for 10 mins. Would you be able to try some frozen methanol or acetone fixed sections as a positive control since IHC-P does not work.


Should the suggestions not improve the results, please do let me know.

In the event that a ab955 is not functioning in the species and applications cited on the product datasheet (and the problem has been reported within 6 months of purchase), we would be pleased to provide a free of charge replacement, credit note, or refund for this tested antibody.

I hope this information is helpful, and I thank you for your cooperation.

Thank you for contacting Abcam.

I feel that both products are suitable for IHC-P. Both have many specific references and in-depth scientific support data right on the datasheet. They differ mainly in the species in which they were raised and in the tags used for detection. Ab6728 is an HRP conjugate whereas Ab6788 is Biotin labeled. I believe that you should choose the secondary which has an associated detection system that you are most familiar with in case you should run into any staining issues.

I hope this information is helpful. Please let me know if you have any questions.
