Background Information

PARD3 (also known as ASIP, Par3, or Bazooka) is one of PARD proteins which are essential for asymmetric cell division and polarized growth. PARD3 is involved in the establishment of cell polarity and in the asymmetric cytokinesis. It plays a role in tight junctions at epithelial cell-cell contacts. PARD3 has three splice isoforms at 100 kDa, 150 kDa, and 180 kDa. This polyclonal antibody raised against C-terminal 281 amino acids of human PARD3 recognizes these three isoforms.

Western blot: Total cell lysate (15 ug) was resolved on a 4-12% Bis-Tris gel and transferred to nitrocellulose membrane. Membrane was incubated in blocking buffer (5% milk/0.1% Tween-20) for 1h. Membrane was incubated with anti-PARD-3 in blocking buffer (1:1000) at 4C overnight. After washing, membrane was incubated in anti-rabbit-HRP in blocking bufffer (1:3000) for 1h at room temperature. Protein was detected using ECL reagent and imaged on a chemiluminescence detection system.Immunofluorescence: Cells fixed in MeOH at -20 degrees were stained with 1:200 primary antibody. After washing, coverslips were incubated in 1:500 AF488 secondary antibody. Following mounting, images were acquired using a confocal microscope. Staining was very weak, as is seen by the image (Green = PARD3, Blue = Hoescht)
