Our Abpromise guarantee covers the use of ab76557 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
ICC/IF Use at an assay dependent concentration.
Flow Cyt Use 0.5µg for 106 cells. ab170191-Mouse monoclonal IgG2a, is suitable for use as an isotype control with this antibody.
WB 1/500 - 1/1000. Detects a band of approximately 38.1 kDa (predicted molecular weight: 12 kDa). This antibody has only been tested in WB against the recombinant fragment used as immunogen. We have no data on the detection of endogenous protein.
ELISA Use at an assay dependent concentration.

Anti-Thymosin alpha 1 antibody images

  • ab76557 staining Thymosin alpha 1 in human paraffin-embedded A549 lung cancer cells by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed using the HOPE technique and permeabilized with 0.05% Tween. Samples were incubated with primary antibody (1/200) for 45 minutes at 25°C. An Alexa Fluor® 488-conjugated goat anti-mouse IgG polyclonal (1/200) was used as the secondary antibody.

    Goat Anti-Mouse IgG (H&L)-HRP Conjugate secondary antibody at 1/5000 dilution

    Predicted band size : 12 kDa
    Observed band size : 38.1 kDa (why is the actual band size different from the predicted?)
  • Overlay histogram showing HL60 cells stained with ab76557 (red line). The cells were fixed with 80% methanol (5 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. The cells were then incubated with the antibody (ab76557, 0.5µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG2a [ICIGG2A] (ab91361, 1µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.
