Anti-HLA Class I 抗体 [MEM-123] (ab2217)


  • 製品名Anti-HLA Class I antibody [MEM-123]
    HLA Class I 一次抗体 製品一覧
  • 製品の詳細
    Mouse monoclonal [MEM-123] to HLA Class I
  • 特異性This antibody reacts with all human classical MHC Class I molecules in native cell-surface forms as well as with human HLA-G cDNA transfected cells. This antibody completely blocks the binding of pan MHC antibody (ab7855) but does not block binding of anti-HLA-G(ab7758/7904) to surface-expressed HLA-G.

Anti-HLA Class I antibody [MEM-123] 画像

  • Flow Cytometry analysis of human peripheral blood cells labeling HLA Class I with Anti-HLA Class I antibody [MEM-123] (ab2217).
  • ICC/IF image of ab2217 stained HeLa cells. The cells were 4% formaldehyde 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 (ab2217, 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.

  • Overlay histogram showing Jurkat cells stained with ab2217 (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 (ab2217, 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 IgG3 [MG3-35] (ab18394, 1µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in Jurkat cells fixed with 80% methanol (5 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.

Thank you for contacting us.

To our knowledge our HLA Class I antibodies have not been tested to not detect HLA-G. I did find that our anti-HLA Class I [MEM-123] antibodies have the following specificity:

Thank you for your email. Ab2217 is isotype IgG3; ab9090 is isotype IgG1; and ab3975 is isotype IgG1. You may also find the isotype information on our online datasheets. If you have any additional questions, please contact us again.

This antibody is reactive only with the native form of the protein but not with the denaturated form (i.e it is not suitable for Western blotting). It is not known if it differs from W6/32 significantly. However, there are some data suggesting that W6/...
