Recombinant Anti-TMPRSS2 antibody [EPR3862] - BSA and Azide free (ab242384)

Anti-TMPRSS2 antibody [EPR3862] (ab109131) at 1/5000 dilution (Purified) + Human prostate lysate

Secondary
Goat Anti-Rabbit IgG (HRP) with minimal cross-reactivity with human IgG at 1/2000 dilution

Predicted band size: 54 kDa

54kDa represents full-length TMPRSS2 and 25kDa is the cleaved form. The molecular weights observed are consistent with what have been described in the literature (PMID: 11245484).

This data was developed using ab109131, the same antibody clone in a different buffer formulation.
Immunocytochemistry analysis of HT-29 (Human colorectal adenocarcinoma epithelial cell) cells labeling TMPRSS2 with Purified ab109131 at 1/200 dilution (8.86 µg/mL). Cells were fixed in 4% Paraformaldehyde and permeabilized with 0.1% tritonX-100. Cells were counterstained with Ab195889 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) 1/200 dilution (2.5 µg/mL). Goat anti rabbit IgG (Alexa Fluor® 488, ab150077) was used as the secondary antibody at 1/1000 dilution (2 µg/mL). DAPI (blue) was used as nuclear counterstain. PBS instead of the primary antibody was used as the secondary antibody only control.

This data was developed using ab109131, the same antibody clone in a different buffer formulation.

ab109131 staining TMPRSS2 in Human prostate adenocarcinoma tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed and paraffin-embedded, antigen retrieval was by heat mediation in Tris/EDTA buffer pH9. Samples were incubated with primary antibody (1/1000). An undiluted HRP-conjugated mouse anti-rabbit IgG was used as the secondary antibody. Tissue counterstained with Hematoxylin. PBS was used in the negative control rather than the Primary antibody.

ab109131 staining TMPRSS2 in the HT-29 cell line by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with 4% Paraformaldehyde permeabilized with 0.1% Triton X-100. Samples were incubated with primary antibody (1/150). ab150077(1/500) an Alexa Fluor®488-conjugated Goat anti-rabbit IgG was used as the secondary antibody. Nuclei were counterstained with DAPI.
