Our Abpromise guarantee covers the use of ab100792 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
WB Use a concentration of 1 µg/ml. Detects a band of approximately 41 kDa (predicted molecular weight: 39 kDa).

Abcam recommends using 5% BSA as the blocking agent.

ICC/IF Use a concentration of 5 µg/ml.


  • Function
    Ligand for members of the frizzled family of seven transmembrane receptors. Probable developmental protein. Signaling by Wnt-7a allows sexually dimorphic development of the mullerian ducts.
  • Tissue specificity
    Expression is restricted to placenta, kidney, testis, uterus, fetal lung, and fetal and adult brain.
  • Involvement in disease
    Defects in WNT7A are the cause of limb/pelvis-hypoplasia/aplasia syndrome (LPHAS) [MIM:276820]; also known as absence of ulna and fibula with severe limb deficiency. LPHAS is a limb-malformation disorder characterized by various degrees of limb aplasia/hypoplasia and joint dysplasia.
    Defects in WNT7A are a cause of Fuhrmann syndrome (FUHRS) [MIM:228930]; also known as fibular aplasia or hypoplasia femoral bowing and poly- syn- and oligodactyly. Fuhrmann syndrome is a distinct limb-malformation disorder characterized also by various degrees of limb aplasia/hypoplasia and joint dysplasia.

  • Anti-Wnt7a antibody (ab100792) 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: 39 kDa
    Observed band size: 41 kDa (why is the actual band size different from the predicted?)
    Additional bands at: 15 kDa, 28 kDa. We are unsure as to the identity of these extra bands.

    Exposure time: 16 minutes
  • ICC/IF image of ab100792 stained HepG2 cells. The cells were 4% PFA 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 (ab100792, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 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. This antibody also gave a positive result in 4% PFA fixed (10 min) HeLa, Hek293 and MCF7 cells at 5µg/ml, and in 100% methanol fixed (5 min) HepG2 and MCF7 cells at 5µg/ml.

Thank you for your reply.

I contacted with my lab colleagues who confirmed this lot has successfully passed our QC controls, and as with previous batches, it should be detecting a band at ˜40KDa, rather than 48KDa.

Please find attac...

Thank you for taking the time to complete our questionnaire.

The predicted band size for this protein is 39KDa, however, attending at our in-house tests, the observed band size appears at approximately 41KDa, and other unknown additional band...
