Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Melanoma gp100 antibody [EP4863(2)] (AB137078)

ab137078 staining Melanoma gp100 in human melanoma tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with paraformaldehyde and antigen retrieval was by heat mediation in a EDTA buffer. Samples were incubated with primary antibody at a dilution of 1/250 for 30 minutes at room temperature. Rabbit specific IHC polymer detection kit HRP/DAB (ab209101) was used as the secondary antibody.

The immunostaining staining was performed on a Leica Biosystems BOND® RX instrument.

Flow cytometry overlay histogram showing left Malme-3M positive cells and right negative A-375 stained with ab137078 (red line). The cells were fixed with 4% formaldehyde (10 min) and then permeabilised with 0.1% PBS-Triton X-100 for 15 mins. The cells were then incubated in 1x PBS containing 10% normal goat serum to block non-specific protein-protein interaction followed by the antibody (ab137078) (1x 10⁶ in 100μl at 1.0μg/ml (1/500 dilution)) for 30 mins at 22°C.

The secondary antibody Goat Anti-Rabbit IgG H&L (Alexa Fluor^® 488) preadsorbed was incubated at 1/4000 dilution for 30 mins at 22°C

Isotype control antibody (black line) was Recombinant Rabbit IgG, monoclonal [EPR25A] - Isotype Control (ab172730) used at the same concentration and conditions as the primary antibody. Unlabelled sample (blue line) was also used as a control.

Acquisition of >5000 events were collected using a 50 mW Blue laser (488nm) and 525/40 bandpass filter.

Flow cytometry overlay histogram showing left B16-F10 positive cells and right negative Raw264.7 stained with ab137078 (red line). The cells were fixed with 80% methanol (5 mins) and then permeabilised with 0.1% PBS-Triton X-100 for 15 mins. The cells were then incubated in 1x PBS containing 10μg/ml anti CD16/CD32 and 10% normal goat serum to block FC receptors and non-specific protein-protein interaction followed by the antibody (ab137078) (1x 10⁶ in 100μl at 1.0μg/ml (1/500 dilution)) for 30 mins at 22°C.

Immunocytochemistry/ Immunofluorescence - Anti-Melanoma gp100 antibody [EP4863(2)] (AB137078)

ab137078 staining Melanoma gp100 in B16-F0 (mouse skin) cells by ICC (Immunocytochemistry). Cells were fixed with 4% Paraformaldehyde and permeabilized with 0.1% Triton X-100. Samples were incubated with primary antibody at a dilution of 1/50. A goat anti rabbit IgG (Alexa Fluor® 488) (ab150077) was used as the secondary antibody at a dilution of 1/1000. Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) ab195889 was used as a counterstain at a dilution of 1/200. DAPI was used as a nuclear counterstain.
