Tissue/cell: human lung carcinoma; 4% Paraformaldehyde-fixed and paraffin-embedded;
Antigen retrieval: citrate buffer ( 0.01M, pH 6.0 ), Boiling bathing for 15min; Block endogenous peroxidase by 3% Hydrogen peroxide for 30min; Blocking buffer (normal goat serum,SLC0005) at 37℃ for 20 min;
Incubation: Anti-MHC Class II/HLA-DPB1 Polyclonal Antibody, Unconjugated(SL4107R) 1:200, overnight at 4°C, followed by conjugation to the secondary antibody(SP-0023) and DAB(SLC0010) staining
Blank control: Mouse spleen.
Primary Antibody (green line): Rabbit Anti-MHC Class II/HLA DMB/AF647 Conjugated antibody (SL4107R-AF647)
Dilution: 0.2μg /10^6 cells;
Isotype Control Antibody (orange line): Rabbit IgG-AF647 .
Protocol
The cells were fixed with 4% PFA (10min at room temperature)and then permeabilized with 0.1% PBST for 20 min at-20℃. The cells were then incubated in 5% BSA to block non-specific protein-protein interactions for 30 min at room temperature. The cells were stained with Primary Antibody for 30 min at room temperature. Acquisition of 20,000 events was performed.
