Our Abpromise guarantee covers the use of ab104238 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 Use a concentration of 1 µg/ml. Detects a band of approximately 62 kDa (predicted molecular weight: 58 kDa).
ICC/IF Use a concentration of 5 µg/ml.
IP Use a concentration of 5 µg/ml.


  • FunctionRegulates, cooperatively with NONO and SFPQ, androgen receptor-mediated gene transcription activity in Sertoli cell line (By similarity). Binds to poly(A), poly(G) and poly(U) RNA homopolymers.
  • Tissue specificityExpressed in pancreas, kidney, skeletal muscle, liver, lung, placenta, brain and heart.
  • Sequence similaritiesBelongs to the PSPC family.
    Contains 2 RRM (RNA recognition motif) domains.
  • Post-translational
    Phosphorylated upon DNA damage, probably by ATM or ATR.
  • Cellular localizationNucleus > nucleolus. Nucleus matrix. Cytoplasm. In punctate subnuclear structures often located adjacent to splicing speckles, called paraspeckles. Colocalizes with NONO and SFPQ in paraspeckles and perinucleolar caps in a RNA-dependent manner. May cycles between paraspeckles and nucleolus. In telophase, when daughter nuclei form, localizes to perinucleolar caps.

Anti-PSPC1 antibody images

  • PSPC1 was immunoprecipitated using 0.5mg Hek293 whole cell extract, 5µg of Rabbit polyclonal to and 50µl of protein G magnetic beads (+). No antibody was added to the control (-).

    The antibody was incubated under agitation with Protein G beads for 10min, Hek293 whole cell extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.

    Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70°C; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab104238.

    Secondary: Mouse monoclonal [SB62a] Secondary Antibody to Rabbit IgG light chain (HRP) (ab99697).

    Band: 62kDa, non specific bands - 50 and 55kDa: We are unsure as to the identity of this extra band; PSPC1

    Goat Anti-Rabbit IgG H&L (HRP) preadsorbed (ab97080) at 1/5000 dilution
    developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 58 kDa
    Observed band size : 62 kDa (why is the actual band size different from the predicted?)

    Exposure time : 2 minutes
  • ICC/IF image of ab104238 stained HepG2 cells. The cells were 100% methnaol 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 (ab104238, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, 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 100% methanol fixed (5 min) MCF7 cells at 5µg/ml.
