Lanes 1-2 : Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/100000 dilution
Lanes 3-5 : Goat Anti-Rabbit IgG Peroxidase Conjugate, specific to the non-reduced form of IgG at 1/100000 dilution

Predicted band size: 100 kDa
Observed band size: 110,130 kDa why is the actual band size different from the predicted?

Blocking/Dilution buffer: 5% NFDM/TBST.

Exposure time: Lane 1/2: 30 seconds; Lane 3: 5 seconds; Lane 4/5: 3 minutes.

The molecular weight observed is consistent with what has been described in the literature(PMID: 22553038).

Immunohistochemical analysis of paraffin-embedded human cardiac muscle tissue labeling N Cadherin with ab207608 at 1/500 dilution, followed by Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/500 dilution.

Intercalated disc staining on human cardiac muscle 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.

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

Secondary
All lanes : Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/20000 dilution

Predicted band size: 100 kDa
Observed band size: 110-130 kDa why is the actual band size different from the predicted?

Exposure time:

Lane 1 and 2: 4 seconds
Lane 4 to 11: 1 seconds

The molecular weight observed is consistent with what has been described in the literature (PMID: 22553038). This antibody fails to detect N Cadherin in HCT 116 cell which is positive described in the literature (PMID: 23431386 and 26540342)

Immunohistochemical analysis of paraffin-embedded human endometrium tissue labeling N Cadherin with ab207608 at 1/500 dilution, followed by Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/500 dilution.

Membrane staining on human endometrium 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.
