WB
Western blot analysis of E-Cadherin on different lysates with Rabbit anti-E-Cadherin antibody at 1/5,000 dilution.
Lane 1: MCF7 cell lysate,
Lane 2: MDA-MB-231 cell lysate (negative),
Lane 3: HT-29 cell lysate,
Lane 4: HCT 116 cell lysate,
Lane 5: A431 cell lysate,
Lane 6: Caco-2 cell lysate,
Lysates/proteins at 20 µg/Lane.
Exposure time: 43 seconds;
4-20% SDS-PAGE gel.
Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody at 1/5,000 dilution was used in 5% NFDM/TBST at 4℃ overnight. Goat Anti-Rabbit IgG - HRP Secondary Antibody at 1/50,000 dilution was used for 1 hour at room temperature.
IHC
Immunohistochemical analysis of paraffin-embedded human lung carcinoma tissue with Rabbit anti-E-Cadherin antibody at 1/200 dilution.
The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0) for 20 minutes. The tissues were blocked in 1% BSA for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody at 1/200 dilution for 1 hour at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.
ICC/IF
Immunocytochemistry analysis of HT-29 (positive) and MDA-MB-231 (negative) cells labeling E-Cadherin with Rabbit anti-E-Cadherin antibody at 1/2,000 dilution.
Cells were fixed in 4% paraformaldehyde for 20 minutes at room temperature, permeabilized with 0.1% Triton X-100 in PBS for 5 minutes at room temperature, then blocked with 1% BSA in 10% negative goat serum for 1 hour at room temperature. Cells were then incubated with Rabbit anti-E-Cadherin antibody at 1/2,000 dilution in 1% BSA in PBST overnight at 4 ℃. Goat Anti-Rabbit IgG H&L (488) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. Nuclear DNA was labelled in blue with DAPI.
Beta tubulin (red) was stained at 1/100 dilution overnight at +4℃. Goat Anti-Mouse IgG H&L (594) was used as the secondary antibody at 1/1,000 dilution.
IF-P
Immunofluorescence analysis of paraffin-embedded human colon tissue labeling E-Cadherin with Rabbit anti-E-Cadherin antibody at 1/50 dilution.
The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0) for 20 minutes. The tissues were blocked in 10% negative goat serum for 1 hour at room temperature, washed with PBS, and then probed with the primary antibody (reen) at 1/50 dilution overnight at 4 ℃, washed with PBS.
Goat Anti-Rabbit IgG H&L (488) was used as the secondary antibody at 1/1,000 dilution. Nuclei were counterstained with Hoechst 33258 (blue).
FC
Flow cytometric analysis of HT-29 (positive, red) and MDA-MB-231 (negative, green) cells labeling E-Cadherin.
Cells were fixed and permeabilized. Then stained with the primary antibody (red) at 1/1,000 dilution, compared with Rabbit IgG Isotype Control (HT-29 black, MDA-MB-231 light green). After incubation of the primary antibody at +4℃ for an hour, the cells were stained with a 488 conjugate-Goat anti-Rabbit IgG Secondary antibody at 1/1,000 dilution for 30 minutes at +4℃.
