IP Use at an assay dependent dilution.
ChIP Use at an assay dependent concentration. PubMed: 20357003


  • RelevanceThe PDD1 gene sequence predicts a novel polypeptide containing two copies of a chromodomain, a conserved domain found in a number of heterochromatin-associated proteins (Koonin et al. 1995). Consistent with this finding, Pdd1p localizes to electron-dense heterochromatic structures that concentrate at the periphery of macronuclear anlagen during the time when DNA deletion occurs.

    • ab5338 staining Pdd1 in wild-type Tetrahymena sp. cells by Immunocytochemistry/ Immunofluorescence. Cells were fixed in methanol. The primary antibody was diluted 1/250 in TBS + 1% Goat Serum and incubated with the sample for 18 hours at 4°C. The secondary antibody was Alexa Fluor® 488-conjugated Goat anti-Rabbit polyclonal, diluted 1/1000.
