  • Positive control
    • Whole cell lysate from a human monocytic KG-1 cell line, mouse multipotential hematopoietic EML cell line or mouse pre-B 70 Z/3 cell line. This antibody gave a positive result in IF in the following Formaldehyde fixed cell line: HeLa.



Our Abpromise guarantee covers the use of ab10361 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB 1/10000 - 1/20000. Detects a band of approximately 140 kDa (predicted molecular weight: 127 kDa).
IP Use at 5-10 µg/mg of lysate.
IHC-Fr Use at an assay dependent concentration. PubMed: 21865157
ICC/IF Use a concentration of 5 µg/ml.


  • Function
    Sequence-specific RNA-binding protein that regulates translation and mRNA stability by binding the 3'-UTR of mRNA targets. Its interactions and tissue specificity suggest that it may be required to support proliferation and self-renewal of stem cells by regulating the translation of key transcripts.
  • Tissue specificity
    Expressed in male germ cells of adult testis (at protein level). Highly expressed in testis and ovary. Predominantly expressed in stem cells and germ cells. Expressed at lower level in brain, heart, kidney, liver, muscle, placenta, intestine and stomach Expressed in cerebellum, corpus callosum, caudate nucleus, hippocampus, medulla oblongata and putamen. Expressed in all fetal tissues tested.
  • Sequence similarities
    Contains 1 PUM-HD domain.
    Contains 8 pumilio repeats.
  • Domain
    The pumilio repeats mediate the association with RNA by packing together to form a right-handed superhelix that approximates a half doughnut. The number as well as the specific sequence of the repeats determine the specificity for target mRNAs.
  • Cellular localization
    Cytoplasm. Cytoplasmic granule. Cytoplasm > perinuclear region. The cytoplasmic granules are stress granules which are a dense aggregation in the cytosol composed of proteins and RNAs that appear when the cell is under stress. Colocalizes with NANOS3 in the stress granules (By similarity). Colocalizes with NANOS1 and SNAPIN in the perinuclear region of germ cells.

    ab10361 detection of human and mouse Pumilio 2 by Western blot. Samples: Whole cell lysate (50 mg) from a human monocytic (KG-1; lane 1), mouse multipotential hematopoietic (EML; lane 2) or mouse pre-B (70 Z/3; lane 3) cell lines. Antibody: ab10361 used at 0.1 mg/ml. Detection: Chemiluminescence with 3 to 5 minute exposure.
  • ICC/IF image of ab10361 stained HeLa cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab10361 at 5µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

Thank you for contacting Abcam. As we do not know the exact immunogen sequence for ab10361 and the similarity between the human and sea urchin is not high, I would not suggest that particular antibody. I would however recommend trying ab57049, as we kn...
