Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-BRCA2 antibody [EPR26146-81] (AB322104)

Immunohistochemical analysis of formalin fixed paraffin embedded human tonsil labelling BRCA2 with ab322104 at a concentration of 1µg/ml. The immunostaining was performed on a Ventana DISCOVERY ULTRA (Roche Tissue Diagnostics) instrument with a OptiView DAB IHC Detection Kit. Heat mediated antigen retrieval was performed with DISCOVERY cell conditioning solution (CC1) 100°C, pH8.5 for 32mins.

ab322104 anti-BRCA2 antibody [EPR26146-81] was incubated for 16mins at 37°C. Sections were counterstained with Hematoxylin II. Image inset shows absence of staining in secondary antibody only control.

Western blot - Anti-BRCA2 antibody [EPR26146-81] (AB322104)

Blocking and diluting buffer and concentration : 5% NFDM/TBST.

To minimize protein degradation, cells were lysed immediately after harvest and then applied to a gel and transfer membrane for Western blotting as soon as possible.

The identity of the lower MW band at approximately 130 kDa is unknown.

The band beneath the target band (200 kDa) is expected to be degradation product.

In Western blot, Anti-Vinculin antibody [EPR8185] (ab129002) staining at 1/10000 dilution.

Western blot - Anti-BRCA2 antibody [EPR26146-81] (AB322104)

Blocking and diluting buffer and concentration : 5% NFDM/TBST.

Capan-1 cells have one copy of BRCA2 gene missing and a mutation in the remaining copy resulting in a truncation of the protein (180kDa).

To minimize protein degradation, cells were lysed immediately after harvest and then applied to a gel and transfer membrane for Western blotting as soon as possible.

The band beneath the target band (250 kDa) is likely to be degradation product.

The identity of the lower MW band at approximately 130 kDa is unknown.
