  • Flow Cytometry analysis of BxPC-3 (human Pancreas adenocarcinoma) cells labeling S100P with purified ab124743 at 1/1700 dilution (1ug/ml) (red). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. A Goat anti rabbit IgG (Alexa Fluor® 488)(1/2000 dilution) was used as the secondary antibody. Rabbit monoclonal IgG (Black) was used as the isotype control, cells without incubation with primary antibody and secondary antibody (Blue) were used as the unlabeled control.

  • Immunohistochemical staining of paraffin embedded human pancreatic adenocarcinoma with purified ab124743 at a working dilution of 1 in 300. The secondary antibody used is a HRP polymer for rabbit IgG. The sample is counter-stained with hematoxylin. Antigen retrieval was perfomed using Tris-EDTA buffer, pH 9.0. PBS was used instead of the primary antibody as the negative control, and is shown in the inset.

  • Immunofluorescence staining of BxPC-3 cells with purified ab124743 at a working dilution of 1 in 150, counter-stained with DAPI. The secondary antibody was Alexa Fluor® 555 goat anti-rabbit, used at a dilution of 1 in 500. The cells were fixed in 4% PFA. The negative control is shown in bottom right hand panel - for the negative control, purified ab124743 was used at a dilution of 1/200 followed by an Alexa Fluor® 555 goat anti-mouse antibody at a dilution of 1/500.

Customer reviews and Q&As


Thanks for contacting us. The immunogen for ab124743 Anti-S100P, has 56% sequence similarity with S100A1, and 33% with S100B. Therefore, it is unlikely that the antibody will cross react with either of these proteins.

I hope this information is helpful. If you have any other questions please let me know. Have a good day.
