Dylight 488 affinipure goat anti rabbit igg

Tissue sections were treated as described above. After treatment with 0.1% Triton X-100, the sections were blocked with 10% goat serum and incubated over night at 4 °C with a mouse RIP1 monoclonal antibody (Abcam, Cambridge, MA, USA; 1:100 dilution) and a rabbit RIP3 polyclonal antibody (Abcam, Cambridge, MA, USA; 1:100 dilution), followed by incubation with Dylight 594 AffiniPure goat anti-mouse IgG and Dylight 488 AffiniPure goat anti-rabbit IgG (EarthOx, San Francisco, CA, USA). After three washes with 0.1 MPBS, the sections were counterstained with DAPI. Finally, the numbers of total cells and RIP1/-RIP3-positive cells were determined using a laser scanning confocal microscope (LEICA TCS SP2, Wetzlar, Germany).

Experimental cells (2 × 10⁵) that had been allowed for overnight growth on a cover glass placed in 6-well plates were transfected for 6 h with an expression construct for the ER/DsRed marker protein and then were allowed for 12-h recovery from transfection in the fresh complete medium. The cells were fixed for 15 min with 4% paraformaldehyde in PBS buffer. Thereafter, the cells were permeabilized for 10 min with 0.1% Triton X-100 in PBS, before immunocytochemistry with the primary antibodies against Nrf1 (dilution 1:200) at 4 °C overnight. The immunostained cells were visualized after incubation with the DyLight 488 AffiniPure Goat anti-rabbit IgG (dilution 1:200, EarthOx, San Francisco, CA, USA) for 1 h at room temperature in the dark, followed by the nuclear DNA staining with DAPI for 5 min. The fluorescence images was observed and photographed under a confocal microscope (Leica, Germany) as described previously59 (link)106 (link).
