Predicted band size: 43 kDa
Observed band size: 28 kDa
why is the actual band size different from the predicted?

Exposure time: 30 seconds

The expression profile observed is consistent with what has been described in the literature (PMID:12186850).
Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-SIRT3 antibody [EPR19755] (ab217319)

Immunohistochemical analysis of paraffin-embedded human hepatocellular carcinoma tissue labeling SIRT3 with ab217319 at 1/500 dilution, followed by Goat Anti-Rabbit IgG H&L (HRP) ready to use. Cytoplasmic staining on human hepatocellular carcinoma is observed. Counter stained with Hematoxylin.

Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/500 dilution.

According to the literature [PMID: 24774224]: IHC and WB studies both showed a decreased expression of SIRT3 in tumor tissues compared with peritumor tissues. Our IHC-P results also showed decreased expression on about 58% of hepatocellular carcinoma.

Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.

Immunohistochemical analysis of paraffin-embedded human liver tissue labeling SIRT3 with ab217319 at 1/500 dilution, followed by Goat Anti-Rabbit IgG H&L (HRP) ready to use. Cytoplasmic staining on human liver is observed. Counter stained with Hematoxylin.

Immunohistochemical analysis of paraffin-embedded human colon tissue labeling SIRT3 with ab217319 at 1/500 dilution, followed by Goat Anti-Rabbit IgG H&L (HRP) ready to use. Cytoplasmic staining on human colon is observed. Counter stained with Hematoxylin.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-SIRT3 antibody [EPR19755] (ab217319)

Immunohistochemical analysis of paraffin-embedded human colon adenocarcinoma tissue labeling SIRT3 with ab217319 at 1/500 dilution, followed by Goat Anti-Rabbit IgG H&L (HRP) ready to use. Cytoplasmic staining on human well-differentiated colon adenocarcinoma is observed. Counter stained with Hematoxylin.

Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/500 dilution.

Our IHC-P results show that about 75% of well-differentiated colon carcinoma show increased expression.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-SIRT3 antibody [EPR19755] (ab217319)

Immunohistochemical analysis of paraffin-embedded human colon adenocarcinoma tissue labeling SIRT3 with ab217319 at 1/500 dilution, followed by Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/500 dilution. Cytoplasmic staining on human poor- differentiated colon adenocarcinoma is observed. Counter stained with Hematoxylin.

Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/500 dilution.

According to the literature [PMID: 25105144]: SIRT3 expression level was found to be significantly associated with the lymph node metastasis and tumor stages. Our IHC-P results show that about 25% of poor-differentiated colon carcinoma show decreased expression.
