アプリケーション Abreviews 特記事項
ICC/IF Use a concentration of 5 µg/ml.
WB Use a concentration of 1 µg/ml. Detects a band of approximately 351 kDa (predicted molecular weight: 351 kDa). Also detects a band of approximately 296 kDa, which corresponds to the predicted molecular weight of isoform 2.


  • 機能Extracellular matrix protein required for maintenance of the integrity of the skin epithelium and for maintenance of renal epithelia. May be required for epidermal adhesion.
  • 関連疾患Defects in FREM2 are a cause of Fraser syndrome (FRASS) [MIM:219000]. Fraser syndrome is a multisystem malformation usually comprising cryptophthalmos, cutaneous syndactyly, ear abnormalities, renal agenesis and congenital heart defects.
  • 配列類似性Belongs to the FRAS1 family.
    Contains 5 Calx-beta domains.
    Contains 12 CSPG (NG2) repeats.
  • ドメインThe Calx-beta domains bind calcium with high affinity and undergo a major conformational shift upon binding.
  • 細胞内局在Cell membrane.

    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 : 351 kDa
    Observed band size : 351 kDa
    Additional bands at : 100 kDa,296 kDa (possible isoform),45 kDa. We are unsure as to the identity of these extra bands.

  • ICC/IF image of ab75803 stained mouse embryonic stem 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 (ab75803, 5µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit 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.
