  • RelevanceRSPO2 is part of the R-spondin family of proteins that consist of secreted cysteine-rich proteins that can activate beta-catenin signaling via the Frizzled/LRP5/6 receptor complex. R-spondin 2 is required for normal laryngeal-tracheal, lung and limb morphogenesis. RSPO2 expression in required in the apical ectodermal ridge for normal hindlimb development.

    Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution
    Developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 28 kDa
    Observed band size : 26 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 106 kDa. We are unsure as to the identity of these extra bands.

    Exposure time : 12 minutes
  • ab73761 staining RSPO2 in human meniscus tissue by Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections).
    Tissue was fixed in formaldehyde and an enzymatic antigen retrieval step was performed using Protease24. Samples were then blocked using 1% BSA for 15 minutes at 21°C, then incubated with ab73761 at a 1/100 dilution for 16 hours at 21°C. The secondary used was an undiluted biotin conjugated goat anti-rabbit polyclonal.
