Flow Cytometry (Intracellular) - Anti-Met (c-Met) antibody [SP44] - BSA and Azide free (AB243930)

This data was developed using the same antibody clone in a different buffer formulation (ab227637).

Flow cytometry overlay histogram showing wild-type HAP1 (green line) and MET knockout HAP1 cells stained with ab227637 (red line). The cells were fixed with 4% formaldehyde (10 min) and then permeabilized with 0.1% PBS-Triton X-100 for 15 min. The cells were then incubated in 1x PBS containing 10% normal goat serum to block non-specific protein-protein interaction followed by the antibody (ab227637) (1x10⁶ in 100 μl at 0.04 μg/ml) for 30 min at 22°C.

The secondary antibody Goat anti-rabbit IgG H&L (Alexa Fluor^® 488, pre-adsorbed) (ab150081) was used at 1/2000 for 30 min at 22°C.

Isotype control antibody was Rabbit IgG (monoclonal) (ab172730) used at the same concentration and conditions as the primary antibody (wild-type HAP1 - black line MET knockout HAP1 - grey line). Unlabelled sample was also used as a control (this line is not shown for the purpose of simplicity).

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Met (c-Met) antibody [SP44] - BSA and Azide free (AB243930)

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA and sodium azide (ab227637).

Immunohistochemical analysis of paraffin-embedded HeLa wt cell pellet and HeLa MET KO cell pellet labeling MET (c-MET) with ab227637 at 1/50 dilution, followed by a ready to use LeicaDS9800 (Bond™ Polymer Refine Detection). Positive staining in human HeLa wt and negative staining in human HeLa MET KO cells. The section was incubated with ab227637 for 15 mins at room temperature. The immunostaining was performed on a Leica Biosystems BOND® RX instrument. Counterstained with Hematoxylin. Secondary antibody only control : Secondary antibody is a ready to use LeicaDS9800 (Bond™ Polymer Refine Detection). Heat mediated antigen retrieval was performed with Citrate buffer (pH 6.0, Epitope Retrieval Solution 1) for 20 mins

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of Human colon carcinoma tissue sections labeling Met (c-Met) with ab227637 at 1/50 dilution (4.52 µg/ml). Heat mediated antigen retrieval was performed Heat mediated antigen retrieval with sodium citrate buffer (pH 6.0, epitope retrieval solution 1) for 10 mins. Rabbit specific IHC polymer detection kit HRP/DAB (ab209101) was used as the secondary antibody. Negative control : PBS instead of the primary antibody. Hematoxylin was used as a counterstain.

Intracellular Flow Cytometry analysis of HepG2 (Human hepatocellular carcinoma epithelial cell) cells labeling Met (c-Met) with purified ab227637 at 1/20 dilution (11.3μg/ml) (red). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. A Goat anti rabbit IgG (Alexa Fluor^® 488, ab150077) secondary antibody was used at 1/2000 dilution. Isotype control - Rabbit monoclonal IgG (ab172730) / Black. Unlabeled control - Unlabelled cells / blue.

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

The β chain undergoes degradation, resulting in lower molecular weight fragments (PMID : 32522525). To minimize protein degradation, cells/tissues were lysed immediately after harvest and then applied to a gel and transfer membrane for Western blotting right away.

c-Met can undergo glycosylation, resulting in a higher molecular weight. It can also be cleaved into α and β chains (PMID : 34210960). The β chain undergoes degradation, resulting in lower molecular weight fragments (PMID : 32522525). This antibody detects both the full-length c-Met and the β chains.
