Flow Cytometry (Intracellular) - Anti-HP1 gamma/CBX3 (citrulline R108) antibody [EPR19802-202] (AB202107)

Intracellular flow cytometric analysis of 4% paraformaldehyde-fixed HEK-293 (human epithelial cell line from embryonic kidney) cells transfected with GFP-tagged PADI4 (WT) treated with 10 mM CaCl2and 10 μM Ionomycinlabeling HP1 gamma/CBX3 (citrulline R108) with ab202107 at 1/3000 dilution (right panel) compared with a rabbit monoclonal IgG isotype control (ab172730) (left panel). Goat Anti-Rabbit IgG H+L (Alexa Fluorr^® 647) (ab150079) was used as the secondary antibody.

Only CaCl2 and Ionomycin treated, GFP positive cell population result in a positive signal (right panel, Q2).

Immunoprecipitation - Anti-HP1 gamma/CBX3 (citrulline R108) antibody [EPR19802-202] (AB202107)

HP1 gamma/CBX3 (citrulline R108) was immunoprecipitated from 0.35 mg HEK-293 (human epithelial cell line from embryonic kidney) transfected with GFP-tagged PADI4 cell lysate treated with 10 mM CaCl₂ and 10 μM Ionomycin for 2 hours with ab202107 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab202107 at a dilution of 1/2000. VeriBlot for IP Detection Reagent (HRP) (ab131366) was used for detection at 1/10000 dilution.

Lane 1 : HEK-293 transfected with GFP-tagged PADI4 (WT) expression vector whole cell lysate treated with 10 mM CaCl₂ and 10 μM Ionomycin for 2 hours 10 μg (Input).

Lane 2 : ab202107 IP in HEK-293 transfected with GFP-tagged PADI4 (WT) expression vector whole cell lysate treated with 10 mM CaCl₂ and 10 μM Ionomycin for 2 hours.

Lane 3 : Rabbit monoclonal IgG (ab172730) instead of ab202107 in HEK-293 transfected with GFP-tagged PADI4 (WT) expression vector whole cell lysate treated with 10 mM CaCl₂ and 10 μM Ionomycin for 2 hours.

Exposure time : 10 seconds.

Western blot - Anti-HP1 gamma/CBX3 (citrulline R108) antibody [EPR19802-202] (AB202107)

Lane 1 : Wild type HAP1 whole cell lysate (20 μg)
Lane 2 : HP1 gamma/CBX3 knockout HAP1 whole cell lysate (20 μg)
Lane 3 : HUVEC (umbilicalvein/vascular endothelium) whole cell lysate (20 μg)
Lane 4 : HepG2 (human liver hepatocellular carcinoma cell line) whole cell lysate (20 μg)

Lanes 1 - 4 : Merged signal (red and green). Green - ab202107 observed at 23 kDa. Red - loading control, ab8245, observed at 37 kDa.

ab202107 was shown to specifically react with HP1 gamma/CBX3 when HP1 gamma/CBX3 knockout samples were used. Wild-type and HP1 gamma/CBX3 knockout samples were subjected to SDS-PAGE. Antibodies ab202107 and ab8245 (Mouse anti GAPDH loading control) were incubated overnight at 4°C at 1000 dilution and 1/10000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preabsorbed ab216776 secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
