ICC/IF Use at an assay dependent concentration.
WB 1/500 - 1/1000. Detects a band of approximately 39 kDa (predicted molecular weight: 41 kDa).

ターゲット情報

  • 機能Involved in the packaging of pre-mRNA into hnRNP particles, transport of poly(A) mRNA from the nucleus to the cytoplasm and may modulate splice site selection. May play a role in HCV RNA replication.
  • 配列類似性Contains 2 RRM (RNA recognition motif) domains.
  • 翻訳後修飾Arg-194, Arg-206 and Arg-225 are dimethylated, probably to asymmetric dimethylarginine.
    Sumoylated.
  • 細胞内局在Nucleus. Cytoplasm. Localized in cytoplasmic mRNP granules containing untranslated mRNAs. Shuttles continuously between the nucleus and the cytoplasm along with mRNA. Component of ribonucleosomes. In the course of viral infection, colocalizes with HCV NS5B at speckles in the cytoplasm in a HCV-replication dependent manner.

  • All lanes : Anti-hnRNP A1 antibody (ab4791) at 1/500 dilution

    Lane 1 : HeLa Whole Cell Extract
    Lane 2 : HeLa Nuclear Extract

    Secondary
    Goat Anti-Rabbit IgG H&L (HRP) (ab6721) at 1/2000 dilution

    Predicted band size : 41 kDa
    Observed band size : 39 kDa (why is the actual band size different from the predicted?)

    Rabbit polyclonal to hnRNPA1 (ab4791) at 1/500.

    Lane 1: HeLa Whole Cell Extract
    Lane 2: HeLa Nuclear Extract

    Secondary ab: Goat anti-rabbit IgG HRP conjugate ab6721 (1/2000)

  • hnRNP A1 was immunoprecipitated using 0.5mg Hela whole cell extract, 5µg of Rabbit polyclonal to hnRNP A1 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, Hela 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 70oC; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab4791.
    Secondary: Mouse monoclonal [SB62a] Secondary Antibody to Rabbit IgG light chain (HRP) (ab99697).
    Band: 36kDa: hnRNP A1.
  • Immunofluorescent imaging of human cells (U2OS) with ab4791 reveals
    the expected ribonucleoprotein particular staining in the nucleus.

    IF was performed with a standard paraformaldehyde technique (fixed in
    PBS buffered PFH 4% for 5 minutes, permeabilised with 0.5% triton-PBS
    for 5 minutes, blocked with 5% milk / 0.2% tween for one hour. Primary antibody used at 1/200 in 5% milk / 0.2% TWEEN for one hour, secondary antibody for 30 minutes. All blocking and incubation steps carried out at 37 degrees. Nuclei counterstained with Hoechst stain (blue).

  • IHC image of hnRNP A1 staining in human skin FFPE section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab4791, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
