  • All lanes : Anti-Transglutaminase 2 antibody [EP2957] (ab109200) at 1/1000 dilution

    Lane 1 : Wild-type A549 whole cell lysate
    Lane 2 : TGM2 knockout A549 whole cell lysate
    Lane 3 : HeLa whole cell lysate
    Lane 4 : HUVEC whole cell lysate

    Lysates/proteins at 20 µg per lane.

    Predicted band size: 77 kDa

    Lanes 1 - 4: Merged signal (red and green). Green - ab109200 observed at 77 kDa. Red - loading control, ab8245, observed at 37 kDa.

    ab109200 was shown to recognize TGM2 in wild-type A549 cells as signal was lost at the expected MW in TGM2 knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and TGM2 knockout samples were subjected to SDS-PAGE. The membrane was blocked with 3% Milk. Ab109200 and ab8245 (Mouse anti-GAPDH loading control) were incubated overnight at 4°C at 1/10000 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.

  • ab109200, at 1/100 dilution, staining Transglutaminase 2 in paraffin-embedded Human kidney tissue by Immunohistochemistry.

    Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.

  • ab109200 staining Transglutaminase 2 in mouse kidney and heart tissue sections by Immunohistochemistry (IHC-Fr - frozen sections). Tissue was fixed with paraformaldehyde, permeabilized with 0.1% Tween-20 and blocked with 5% BSA for 12 hours at 4°C. Samples were incubated with primary antibody (1/500 in PBS-T + 5% BSA) for 12 hours at 4°C. An undiluted Alexa Fluor® 488-conjugated goat anti-rabbit IgG (H+L) polyclonal was used as the secondary antibody.

Thank you for your enquiry.

I can confirm that ab109200 Transglutaminase 2 antibody [EP2957] has the following alignments to the isoforms of the protein:

Isoform 1 100%
isoform 2 and 3 26%

Therefore, the antibody is not likely to detect isoform 2 and 3.

Please note this is based on alignment only and I am sorry the crossreactivity has not specifically been tested in the laboratory.

I hope this will be helpful. If you have nay further questions, please do not hesitate to contact us.
