![A) Immunofluorescence (IF) of ExpiCHO cells transfected with human NTN1 and labeled with Anti-Netrin-1 [IPI-NTN1.33] (Addgene #241893). Left images show all three channels (IPI-NTN1.33, GFP (transfection control) and DAPI) while the right images only show IPI-NTN1.33 and DAPI. Images taken at 40X magnification. B) Combined quantification of multiple images of the same transfected cells taken at 10X magnification. IPI-NTN1.33 labeling of human Netrin-1 is shown in the top row, and compared to a positive (left) and negative (right) control in the bottom row. IPI-NTN1.33 was used at 0.1 μg/mL (1:10000 dilution).](https://datahub-media.addgene.org/report-images/jcxrgs/NTN1.33_IF-BINDING.png)

Confocal images taken at 40X magnification on an ImageXpress confocal HT.ai microscope.
For quantitative data, GFP-positive cells were identified via the neural network CellPose, then the mean fluorescence intensity (MFI) of the far-red channel for each cell, representing IPI-NTN1.33 labeling, was recorded. Each histogram displays the number of cells with MFIs ranging from below 100 (background fluorescence) to 10000 (saturation).
Controls
Positive control: Anti-V5 [IPI-SV5-Pk1] (Addgene #218107) used to confirm IF labeling efficacy (since construct expressing target also has a V5 tag).
Negative control: Rabbit IgG used to confirm transfected construct does not interact /produce signal with every antibody.
Results
- Result
- Pass (The antibody worked under these conditions)
- Describe Results
- The antibody shows binding to human Netrin-1.
