    See all Integrin alpha 2+beta 1 primary antibodies
  • Description
    Mouse monoclonal [P1E6] to Integrin alpha 2+beta 1
  • Specificityab24697 is directed against the a2 subunit and will precipitate a complex containing a2, including a2ß1 Integrin and neutralizes binding to collagen.
  • Tested applicationsSuitable for: IP, Blocking, Neutralising, Flow Cyt, Inhibition Assay, ICC/IFmore details
  • Species reactivity
    Reacts with: Human
  • Immunogen

    Tissue/ cell preparation (Human): HT1080 fibrosarcoma cells.

  • Positive control
    • IF: HepG2 cell line
  • General notesWe can conjugate this antibody to FITC for you (please see ab150216 for details).

    ab24697 is effective in blocking adhesion cells to collagen coated surfaces. It immunoprecipitates the a2 subunit (reducing) or a2 complexed with ß1 from surface labeled cell lysates (non-reducing). In imunofluorescence, this antibody can be used to detect a2 in collagen dependent focal adhesions.



Our Abpromise guarantee covers the use of ab24697 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Anti-Integrin alpha 2+beta 1 antibody [P1E6] images

  • Overlay histogram showing HT1080 cells stained with ab24697 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab24697, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was a goat anti-mouse DyLight® 488 (IgG; H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive result in 80% methanol (5 min) fixed HT1080 cells used under the same conditions.

    Please note that Abcam do not have any data for use of this antibody on non-fixed cells. We welcome any customer feedback.

  • ICC/IF image of ab24697 stained HepG2 cells. The cells were 4% paraformaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab24697, 10µg/ml) overnight at +4°C. The secondary antibody (green) was ab96879, DyLight® 488 goat anti-mouse IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
