Application Abreviews Notes
WB 1/1000 - 1/10000. Predicted molecular weight: 84 kDa.
IP 1/10 - 1/100.
IHC-P 1/100 - 1/250. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
  • Application notes
    Is unsuitable for ICC/IF.
  • Target

    • Function
      Involved in cell motility. When hyaluronan binds to HMMR, the phosphorylation of a number of proteins, including the focal adhesion kinase occurs. May also be involved in cellular transformation and metastasis formation, and in regulating extracellular-regulated kinase (ERK) activity.
    • Tissue specificity
      Expressed in breast cancer cell lines and in normal breast tissue.
    • Cellular localization
      Cell surface. Cytoplasm.

    • Lane 1: Wild type HAP1 whole cell lysate (20 µg)
      Lane 2: Empty knockout  HAP1 whole cell lysate (20 µg)
      Lane 3: CD168 whole cell lysate (20 µg)              

      Lanes 1 - 3: Merged signal (red and green). Green - ab108339 observed at 90 kDa. Red - loading control, ab9484, observed at 37 kDa.

      ab108339 was shown to specifically react with CD168 when CD168 knockout samples were used. Wild-type and Empty knockout samples were subjected to SDS-PAGE.  Ab108339 and ab9484 (Mouse anti GAPDH loading control) were incubated overnight at 4°C at 1000 dilution and 1/10000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.

    For ab124729 lot GR82264-8, the concentration is 1.797 mg/ml.

    The current lot we have for sale for ab108339 is lot GR106937-4 and that is 0.193 mg/ml.

    There should not be concerns about permeabilizing cells because as soon as they are fixed with parafomraldehyde, they are essentially permeabilized. The CD168 antigen is a non-integral cell surface hyaluronan receptor that is readily accessable to the ...

    A link below is our Flow Cytometry protocol, which we use routinely for in-house testing.
    Our protocol is for intracellular staining and we always fix the cells with 2% paraformaldehyde.

    Thank you for your email.
    I can confirm that ab108339 (Anti-CD168 antibody) would recognize all 4 isoforms of CD168/RHAMM.
    If you need any further assistance in the future, please do not hesitate to contact me.

    Thank you for contacting Abcam earlier today.

    Please find attached the IHC-P protocol for both ab108339 & ab124729.

    If there is anything else I can help you with, please let me know.

    Thank you for contacting us.
    The target CD168 is a cell surface protein. There no need for cell permeabilization and fixation (do not wait longer than an hour). Cell fixatiion is advised if there is a wait longer than an hour between analysis. Avo...
