Properties

Applications

Our Abpromise guarantee covers the use of ab85670 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 35 kDa (predicted molecular weight: 35 kDa).
ICC/IF Use a concentration of 10 µg/ml.
IHC-P Use a concentration of 1 µg/ml. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.

Target

  • Function

    May function as an antagonist of fibroblast growth factor (FGF) pathways and may negatively modulate respiratory organogenesis.
  • Sequence similarities

    Belongs to the sprouty family.
    Contains 1 SPR (sprouty) domain.
  • Domain

    The Cys-rich domain is responsible for the localization of the protein to the membrane ruffles.
  • Cellular localization

    Cytoplasm > cytoskeleton. Cell projection > ruffle membrane. Associated with microtubules in unstimulated cells but is translocated to the membrane ruffles in cells stimulated ith EGF.

    Exposure time: 2 minutes
  • ICC/IF image of ab85670 stained PC12 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 (ab85670, 10µg/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. This antibody also gave a positive result in 100% methanol fixed (5 min) PC12 cells at 10µg/ml.
  • IHC image of Spry-2 staining in human skin melanoma formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab85670, 1µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

Question
Answer

Thank you for your reply.

I am sorry that you have been experiencing difficulties with this antibody in your IHC samples. Unfortunately, this antibody has not been valditated for tissue sections and testing of the antibody in this application has been inconclusive. Therefore we do not guarantee the antibody in IHC-P we have no additional information regarding whether this antibody may be suitable for this application.


I apologize for any inconvenience this may cause. Please do not hesitate to contact me if you have any additional questions.
