Our Abpromise guarantee covers the use of ab103839 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
ICC/IF Use a concentration of 5 µg/ml.
WB Use a concentration of 1 µg/ml. Detects a band of approximately 71 kDa (predicted molecular weight: 71 kDa).


  • Function
    Plays a role in fibroblast growth factor-mediated signaling cascades that lead to the activation of MAP kinases. Promotes neurite outgrowth via FGFR1-mediated activation of downstream MAP kinases. Promotes an increase both in neurite number and in neurite length. May play a role in cell-cell adhesion and cell guidance via its interaction with ADGRL1/LPHN1 and ADGRL3.
  • Tissue specificity
    Expressed in kidney and brain.
  • Sequence similarities
    Contains 1 fibronectin type-III domain.
    Contains 10 LRR (leucine-rich) repeats.
    Contains 1 LRRCT domain.
    Contains 1 LRRNT domain.
  • Post-translational
    Phosphorylated in response to FGFR1 signaling, but is not a direct substrate of FGFR1 or SRC. A mutant where the Tyr phosphorylation sites have been replaced by Phe displays constitutive FGFR1-dependent activation of downstream MAP kinases.
    Proteolytic cleavage in the juxtamembrane region gives rise to a soluble ectodomain.
  • Cellular localization
    Cell membrane. Endoplasmic reticulum membrane. Cytoplasmic vesicle membrane. Cytoplasm, perinuclear region. Cell junction, focal adhesion. Secreted. Cell projection. Cell junction. In addition to its location at the cell membrane, colocalizes with FGFR1 in punctate perinuclear cytoplasmic vesicles. Detected along neurites and at contacts between neurite termini and other cells. Proteolytic cleavage gives rise to a shedded ectodomain.

  • Anti-FLRT1 antibody (ab103839) at 1 µg/ml + Human kidney tissue lysate - total protein (ab30203) at 10 µg

    Goat Anti-Rabbit IgG H&L (HRP) preadsorbed (ab97080) at 1/5000 dilution

    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 71 kDa
    Observed band size: 71 kDa
    Additional bands at: 35 kDa. We are unsure as to the identity of these extra bands.

    Exposure time: 90 seconds
  • ICC/IF image of ab103839 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 ab103839 at 5µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) 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.
