  • Product nameAnti-Syndecan-1 antibody [EPR6454]
    See all Syndecan-1 primary antibodies
  • Description
    Rabbit monoclonal [EPR6454] to Syndecan-1
  • SpecificityBased on negative staining of mouse and rat spleen and stomach tissues in IHC-P we believe this antibody is unsuitable for IHC-P with mouse and rat. We believe the antibody is suitable for Western blot with mouse and rat based on data from brain, heart, kidney, and spleen lysates. Please contact our Scientific Support team for more information.
  • Tested applicationsWB, IHC-P, Flow Cytmore details
  • Species reactivity
    Reacts with: Mouse, Rat, Human
  • Immunogen

    Synthetic peptide (the amino acid sequence is considered to be commercially sensitive) corresponding to Human Syndecan-1 aa 1-300 (extracellular).

    • Overlay histogram showing Raji cells stained with ab128936 (red line). The cells were fixed with 80% methanol (5 min) and incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab128936, 1/1000 dilution) for 30 min at 22°C. The secondary antibody used was Alexa Fluor® 488 goat anti-rabbit IgG (H&L) (ab150077) at 1/2000 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) (1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter. This antibody gave a positive result in 4% paraformaldehyde (10 min) fixed Raji cells used under the same conditions. Please note that Abcam do not have any data for use of this antibody on non-fixed cells. We welcome any customer feedback.

      Predicted band size : 32 kDa
      Observed band size : 35 kDa (why is the actual band size different from the predicted?)
      Additional bands at : 65-100 kDa. We are unsure as to the identity of these extra bands.
