Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Erk1 (pT202/pY204) + Erk2 (pT185/pY187) antibody (AB4819)

Immunohistochemical analysis of paraffin-embedded human breast carcinoma tissue (right) labeling ERK1/2 (pTpY185/187) in the cytoplasm and nucleus with ab4819 at 1/50 dilution, compared to a negative control without primary antibody (left).

To expose target proteins, antigen retrieval was performed using 10mM sodium citrate (pH 6.0), microwaved for 8-15 min. Following antigen retrieval, tissues were blocked in 3% H2O2-methanol for 15 min at room temperature, washed with ddH2O and PBS, and then probed with ab4819 diluted in 3% BSA-PBS at a dilution of 1 : 50 overnight at 4°C in a humidified chamber. Tissues were washed extensively in PBST and detection was performed using an HRP-conjugated secondary antibody followed by colorimetric detection using a DAB kit. Tissues were counterstained with hematoxylin and dehydrated with ethanol and xylene to prep for mounting.

Western blot - Anti-Erk1 (pT202/pY204) + Erk2 (pT185/pY187) antibody (AB4819)

Extracts of PC12 cells were resolved by SDS-PAGE on a 10% Tris-glycine gel and transferred to PVDF.

The membrane was blocked with a 5% BSA-TBST buffer overnight at 4°C, and then incubated with ab4819 for two hours at room temperature in a 3% BSA-TBST buffer, following its prior incubation with :

Lane 1 and 2 : no peptide

Lane 3 : the non-phosphopeptide corresponding to the phosphopeptide immunogen

Lane 4 : a generic phosphothreonine-containing peptide

Lane 5 : a generic phosphotyrosine-containing peptide

Labe 6 : the phosphopeptide immunogen

Detection : Pierce SuperSignal™ method.
