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)

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

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

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.

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

Western blot - Anti-Met (c-Met) antibody [SP44] - BSA and Azide free (AB243930)

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

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

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.

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.
