  • 製品の詳細
    Mouse monoclonal [SC-35] to SC35 - Nuclear Speckle Marker
  • 特異性
    In immunohistology and immunoelectronmicroscopy, the antibody labels SC-35 as a speckled pattern that occupies a portion of the nucleoplasm, excluding the nucleoli. Nie et al (2002) report that "In human endometrium the SC35 protein was detected by western blot analysis and had a molecular mass of approximately 90 kDa, indicating that in the endometrial extracts, the 35 kDa protein remains bound to one or more components of the spliceosome."

    • 機能
      Necessary for the splicing of pre-mRNA. It is required for formation of the earliest ATP-dependent splicing complex and interacts with spliceosomal components bound to both the 5'- and 3'-splice sites during spliceosome assembly. It also is required for ATP-dependent interactions of both U1 and U2 snRNPs with pre-mRNA. Interacts with other spliceosomal components, via the RS domains, to form a bridge between the 5'- and 3'-splice site binding components, U1 snRNP and U2AF. Binds to purine-rich RNA sequences, either 5'-AGSAGAGTA-3' (S=C or G) or 5'-GTTCGAGTA-3'. Can bind to beta-globin mRNA and commit it to the splicing pathway.
    • 配列類似性
      Belongs to the splicing factor SR family.
      Contains 1 RRM (RNA recognition motif) domain.
    • 翻訳後修飾
      Extensively phosphorylated on serine residues in the RS domain.

    This antibody works fine for ICC, but we found that in WB it shows a possible cross-reactivity with the SC35-related non-snRNP factor SF2/ASF (p75) and Ad2 proteins. This may explain your unexpected results.

    Perdona por la espera.

    La mejor manera de evitar bandas inespecíficas es asegurar unas condiciones de preparación de la muestra idóneas para el anticuerpo en cuestión. Este anticuerpo reconoce el epítopo en ...
