Overview

  • Product name
  • Description
    Goat polyclonal to Iba1
  • Host species
    Goat
  • Specificity

    This Iba1 antibody, ab5076, is expected to recognise the isoforms represented by NP_001614 and NP_116573 but not NP_004838.  Please note: Although we have some very good Abreviews on mouse and pig, some customers were receiving inconsistent results on mouse samples. We have therefore removed mouse and pig and can no longer guarantee them. In addition, we recommend blocking in milk. Blocking with BSA gives high background.

    IHC-Fr. Some customers have used this product in IHC-Fr however we have had consistent complaints in this application over the last year and can no longer guarantee performance in this application. If looking for a monoclonal anti-Iba1 alternative we can recommend our RabMAb ab178846. This has the same immunogen as ab5076.

Properties

Applications

Our Abpromise guarantee covers the use of ab5076 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
Electron Microscopy Use at an assay dependent concentration. PubMed: 26358247
IHC-P Use a concentration of 2 - 4 µg/ml. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
WB Use a concentration of 0.3 - 1 µg/ml. Detects a band of approximately 17 kDa (predicted molecular weight: 17 kDa).Can be blocked with Human Iba1 peptide (ab23067).

We received several excellent Abreviews on this antibody working with mouse, however, mouse is not a batch tested species and we cannot guarantee that this antibody will work on mouse. Some of our customers have observed high background in mouse samples. We recommend blocking in milk. Blocking with BSA gives high background.

IHC-FrFl Use at an assay dependent concentration.
ICC Use at an assay dependent concentration.
ICC/IF Use at an assay dependent concentration.

      Lane 1: exposure 1 minute. Lanes 2-16: exposure 4 minutes. Abcam recommends blocking in milk for cleaner blots with reduced background, in comparison to BSA. 

      This blot was produced using a 4-12% Bis-Tris gel under the MOPS buffer system. The gel was run at 200V for 60 minutes before being transferred onto a nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour before being incubated with ab5076 (anti-Iba1 antibody; 1 ug/mL) for 18 hours at 4°C.

    • AIF1 expression in an inflammatory foci in a skin biopsy. Paraffin embedded sections were deparaffinized and boiled in 10mM citrate buffer for 30 min in a microwave to expose the AIF1 antigen, and then blocked with 5% donkey serum for 20 min. Slides were incubated for 40 min with goat-anti-AIF1 antibody (1:100) and rinsed in three changes of PBS for 1 min each.  A secondary antibody (donkey-anti-goat-FITC conjugated IgG; 1:50) was then applied to the slide for 40 min. Sections were washed again to remove the unbound antibody. The slides were counterstained with DaPI and viewed with a Nikon epi-fluorescent microscope. AIF1 positive cells appear green and the nuclei are stained blue. Numerous cells expressing the AIF1 protein are located around a vessel. (400X).
