  • Tested applicationsSuitable for: ICC/IF, IP, Flow Cyt, ELISA, IHC-Frmore details
  • Species reactivity
    Reacts with: Human
  • Immunogen

    Purified human beta 1 preparation from HT1080 fibrosarcoma cell extract.

  • Positive control
    • In IF, this antibody gave a positive signal in HepG2 cells.
  • General notes

    ab30483 is identified as capable of immunoprecipitating a non-reducible alpha subunit from I125 surface labelled Human cell line extract. It is confirmed as specific to the alpha 2 subunit by relative expression of antigen on various cell lines by FACS, and its recognition of affinity purified alpha 2 beta 1 in dot blots.



Our Abpromise guarantee covers the use of ab30483 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 [16B4] images

  • Overlay histogram showing HT1080 cells stained with ab30483 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab30483, 0.1μg/1x106 cells) for 30 min at 22°C. The secondary antibody used was a goat anti-mouse Alexa Fluor® 488 (IgG; H+L) (ab150113) at 1/2000 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter. This antibody gave a positive signal in HT1080 cells fixed with 80% methanol (5 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.

  • ICC/IF image of ab30483 stained HepG2 cells. The cells were 4% PFA 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 (ab30483, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-mouse IgG (H+L) used at a 1/1000 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. This antibody also gave a positive result in 4% PFA fixed (10 min) MCF7 cells at 1µg/ml.
  • ab30483 staining human breast cancer cells by ICC/IF.  Cells were PFA fixed and blocked with 1% serum for 16 hours at 20°C prior to incubating with ab30483 (at 30µg/ml) for 16 hours at 4°C.  An Alexa Fluor® 488 conjugated goat anti-mouse antibody, diluted 1/200, was used as the secondary.

Thank you for your reply.

Based on what you have already tested, I am not sure there are many more steps to be optimized. One consideration would be to extend the primary antibody incubation to overnight at 4oC. Longer incubation with l...
