アプリケーション

Our Abpromise guarantee covers the use of ab69903 in the following tested applications.

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

アプリケーション Abreviews 特記事項
ICC/IF 1/250.
WB Use a concentration of 0.25 µg/ml. Detects a band of approximately 95 kDa (predicted molecular weight: 89 kDa). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
ELISA Use at an assay dependent concentration.

ELISA titre using peptide based assay: 1/62500.

ターゲット情報

  • 機能
    Subunit of the splicing factor SF3A required for 'A' complex assembly formed by the stable binding of U2 snRNP to the branchpoint sequence (BPS) in pre-mRNA. Sequence independent binding of SF3A/SF3B complex upstream of the branch site is essential, it may anchor U2 snRNP to the pre-mRNA. May also be involved in the assembly of the 'E' complex.
  • 組織特異性
    Ubiquitously expressed.
  • 配列類似性
    Contains 2 SURP motif repeats.
    Contains 1 ubiquitin-like domain.
  • 翻訳後修飾
    Phosphorylated upon DNA damage, probably by ATM or ATR.
  • 細胞内局在

  • Immunocytochemistry/Immunofluorescence analysis of HeLa cells labelling SF3A1 with ab69903 at 1/250. Cells wew fixed with 4% PFA for 30 minutes and blocked with 5% goat serum + 1% BSA + 0.02% fish gelatin overnight at 4°C. Cells were incubated with the primary antibody overnight at 4°C. An Alexa Fluor 546-conjugated anti-rabbit IgG (1/500, room temperature, 2 hours) was used as the secondary antibody.

    Predicted band size : 89 kDa
    Observed band size : 95 kDa (why is the actual band size different from the predicted?)
