  • Function
    ICAM proteins are ligands for the leukocyte adhesion protein LFA-1 (integrin alpha-L/beta-2). During leukocyte trans-endothelial migration, ICAM1 engagement promotes the assembly of endothelial apical cups through ARHGEF26/SGEF and RHOG activation. In case of rhinovirus infection acts as a cellular receptor for the virus.
  • Sequence similarities
    Belongs to the immunoglobulin superfamily. ICAM family.
    Contains 5 Ig-like C2-type (immunoglobulin-like) domains.
  • Post-translational
    Monoubiquitinated, which is promoted by MARCH9 and leads to endocytosis.

To check the status of the order please contact our Customer Service team and reference this number.

Please note that this free of charge replacement vial is also covered by our Abpromise guarantee. Should you still be experiencing difficulties, or if you have any further questions, please do not hesitate to let us know.

I wish you the best of luck with your research.

Thank you for the response.

Any monoclonal antibody is produced by a single immune cell, which has been cloned. These will only recognize a single epitope of the target protein. This epitope typically is 5-10 amino acids in length. Therefore any single monoclonal antibody will only recognize a region within a single domain and not stain both the intracellular and extracellular region of the target protein.

Polyclonal antibodies are created by many different immune cells and will contain multiple epitope recognition sites. Although the amount of antibody specific to a particular epitope will vary from lot-to-lot, it is possible for a polyclonal to therefore contain antibodies which will recognize different domains.

I have reviewed the antibodies which you have listed as well as other polyclonals in our catalog to try and find a product which might be able to recognize the intracellular and extracellular regions.

ab2213Anti-ICAM1 antibody [MEM-111]: This monoclonal antibody was created with an immunogen from a whole tissue / cell preparation (Human). We have not mapped the exact location of the epitope. Therefore the epitope recognized might be intracellular, transmembrane or extracellular.

ab25375Anti-ICAM1 antibody [YN1/1.7.4]: This product is also monoclonal.The details of the immunogen for this antibody are not available. However as a monoclonal, this product will not be able to recognize sites in multiple domains.

ab7815Anti-ICAM1 antibody (Biotin): This product is a rabbit polyclonal and has been raised against the whole protein. As such it is possible that the product will contain antibodies against both extracellular and intracellular regions. We do not test for this type of response and cannot guarantee that the productwill recognizeboth domains. Please be aware that this product is also biotin labeled.

Our other rabbit polyclonal antibodies were each created from recombinant fragments and would also not be able to recognize both extracellular and intracellular domains.

I hope this information is helpful. Please do not hesitate to contact me with further questions.

Perdona por la tardanza en contestar, estaba chequeando con mis compañeros del laboratorio las distintas opciones de reactividad cruzada de este anticuerpo con conejo. Desgraciadamente no hay muchos datos al respecto, ya que ninguno de ellos se ha testado en esta especie, y muchos de los epítopos no han sido mapeados, por lo que no puede llevarse a cabo un BLAST.

Así pues, si sigues interesada en testarlo en conejo, a pesar de no tener datos concretos acerca de las posibilidades de reactividad, te puedo mandar un código para canjear por un anticuerpo gratuito si nos envías los resultados (independientemente de si estos resultan positivos o no).

Para detectar I CAM1 yo me inclinaría por ab25375 o ab27294, y en el caso de V CAM1 por ab78712 o ab98954.

Es importante que antes de realizar el pedido te emita el código valido para el anticuerpo gratuito por participar en el sistema Abreviews, así que te pediría que antes de hacer el pedido, por favor, esperes a que te lo comunique.

¿Qué tal han ido los resultados con ab25072?

Respecto a la duda de los Abreviews, te cuento. Si se trata de una aplicación o especie que no se ha testado hasta el momento, la compensación por participar en el sistema Abreview es un código (emitido ANTES de realizar el pedido) válido por un anticuerpo primario completamente gratuito, y también una serie de puntos (Abpoints) canjeables por distintas opciones.

Si, por el contrario, los resultados enviados corresponden a información adicional sobre especies o aplicaciones ya testadas, en ese caso se ofrecen (Abpoints), pues ayudan a completar la información y referencias del anticuerpo.

Respecto a los anticuerpos que ya habéis probado en el pasado, siempre podéis publicar los resultados, pero aunque sean nuevas aplicaciones / especies no podremos ofreceros un código de descuento ya que el pedido se ha realizado con anterioridad a dicho código. Aun así, podéis mandar los resultados, y ser compensados con puntos.

Espero haberte aclarado. Quedo a la espera de recibir tu respuesta para que me indiques como proceder. Si tienes más dudas, por favor, no dudes en volvernos a contactar.

Here is my reply to your questions. Batch number: lot # 155779 Purchase order number 61281D or preferably Abcam order number: General Information Antibody storage conditions (temperature/reconstitution etc): 4 C Description of the problem (high background, wrong band size, more bands, no band etc.): Not picking up anything definitive b/t 85 and 110 kDa Sample (Species/Cell extract/Nuclear extract/Purified protein/Recombinant protein etc.): Mouse Brain Whole Cell Lysates Sample preparation (Buffer/Protease inhibitors/Heating sample etc.): 1X 'Cell Signaling' Cell Lysis Buffer Amount of protein loaded: Loading max amount of 350ug Electrophoresis/Gel conditions (Reducing or Non-reducing gel, % of the gel etc.): Reducing, 10% gel Transfer and blocking conditions (Buffer/time period, Blocking agent etc.): Transfer 100V, 30 min. Block 5%milk for 1 hour room temp. Primary Antibody (Manufacturer/Species/Diluent/Dilution/Incubation time, Wash step): Ab25375, 1:1000 dilution overnight @ 4C Wash 5X 15 min each Secondary Antibody (Manufacturer/Species/Diluent/Dilution/Incubation time, Wash step): Ab6734-1 Detection method (ECL, ECLPlus etc.): Amersham ECL Positive and negative controls used (please specify): Using Hela cells, max loading of 30ul, boiled for 5 min. Optimization attempts (problem solving): Changed dilution of secondary from 1:1000 to 1:500, max loading the protein to pick up the band, Re- running the blots, etc. How many times have you tried the Western? 10 times Have you run a "No Primary" control? Yes Do you obtain the same results every time? Yes What steps have you altered? See optimization attempts above Additional Notes: We are having a difficult time even picking up the pos. Hela control. We have used 5 different lots of Hela controls and none show up with this antibody. We are getting many non-specific bands. I think the antibody might be unstable, since from the first time we have used it, we have never had a positive result.

Thank you for providing these details regarding your protocol. Ab25375 should detect a band at approximately 58 kDa; did you see a band at this size? This particular antibody has only so far been tested for cross-reactivity with mouse and has not yet been tested for cross-reactivity with human. So even though HeLa samples should in theory be a good control (as CD54 is expressed on endothelial cells) we don't know if this antibody detects human ICAM1. To help decrease the amount of non-specific bands that you are seeing, I would suggest loading less lysate on your gel (we recommend 20-30 ug; 350 ug is too much) and decrease the amount of primary and secondary that you are using as well as the incubation periods. You can try the primary at 1:1000 for 2 hrs at RT or at 1:2000. For the secondary you can try it at a dilution of 1:5000. Please let me know if these suggestions help. If not, I can certainly offer you a free of charge replacement, a credit note or a refund.
