アプリケーション Abreviews 特記事項
WB 1/500 - 1/1000. Detects a band of approximately 39 kDa (predicted molecular weight: 31 kDa).
IHC-P Use a concentration of 1.5 µg/ml.
ICC/IF Use at an assay dependent dilution. NOTE: Product requires purification with Protein A prior to use in ICC/IF and IHC-P.


  • 関連性SFRS5 plays a role in constitutive splicing and can modulate the selection of alternative splice sites. It is found in a pre-mRNA splicing complex with SFRS4, SNRP70, SNRPA1, SRRM1 and SRRM2. There are four isoforms.

  • Anti-SFRS5 antibody (ab67175) at 1/500 dilution + human liver tissue lysate at 25 µg/ml

    Goat Anti-Mouse IgG (H&L)-HRP Conjugate at 1/2500 dilution

    Predicted band size : 31 kDa
    Observed band size : 39 kDa (why is the actual band size different from the predicted?)
  • All lanes : Anti-SFRS5 antibody (ab67175) at 1/500 dilution

    Lane 2 : Non-transfected 293T cell lysate

    Lysates/proteins at 25 µg/ml per lane.

    Goat Anti-Mouse IgG (H&L)-HRP Conjugate at 1/2500 dilution

    Predicted band size : 31 kDa
    Observed band size : 39 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 27 kDa. We are unsure as to the identity of these extra bands.
  • ab67175, at 1.5µg/ml, staining SFRS5 in human ovary by immunohistochemistry using formalin-fixed, paraffin-embedded tissue.
  • ICC/IF image of ab67175 stained HeLa cells. The cells were 4% formaldehyde fixed (10 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 (ab67175, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-mouse IgG (H+L) used at a 1/1000 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.
