Properties

Applications

Our Abpromise guarantee covers the use of ab21628 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
ICC Use at an assay dependent concentration.
WB Use a concentration of 1 µg/ml. Detects a band of approximately 39 kDa (predicted molecular weight: 39 kDa).
  • Application notes
    Is unsuitable for IHC-P.

    • Target

    • Function

      RNA binding protein that regulates the expression of target mRNAs at the translation level. Regulates expression of the NOTCH1 antagonist NUMB. Binds RNA containing the sequence 5'-GUUAGUUAGUUAGUU-3' and other sequences containing the pattern 5'-[GA]U(1-3)AGU-3'. May play a role in the proliferation and maintenance of stem cells in the central nervous system.

    • Tissue specificity

      Detected in fetal kidney, brain, liver and lung, and in adult brain and pancreas. Detected in hepatoma cell lines.

    • Sequence similarities

      Belongs to the Musashi family.
      Contains 2 RRM (RNA recognition motif) domains.

    • Domain

      The first RNA recognition motif binds more strongly to RNA compared to the second one.

    • Cellular localization

      Cytoplasm. Nucleus.

      ICC/IF image of ab21628 stained PC12 cells. The cells were 100% methanol fixed (5 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 (ab21628, 10µg/ml) overnight at +4°C. The secondary antibody (green) was a96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 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. This antibody also gave a positive result in 4% PFA fixed (10 min) PC12 cells at 10µg/ml.
