![Each graph depicts the combined quantification of multiple images of the same transfected cells taken at 10X magnification. GFP- or BFP-positive cells were identified and the mean fluorescence intensity (MFI) of the far-red channel for each cell, representing Anti-Neuroligin-3 [IPI-mNLGN3.3] (Addgene #219625) labeling, was recorded. IPI-mNLGN3.3 labeling of human and mouse variants of each related family member is compared on the top and bottom rows. To test family-wide cross-reactivity, IPI-mNLGN3.3 was used at 0.1 µg/mL (1:10,000 dilution).](https://datahub-media.addgene.org/report-images/yv9ng1/mNLGN3.3_IF-SPECIFICITY.png)

Additional Information
- Additional Information
GFP- or BFP-positive cells were identified via the neural network CellPose, then the mean fluorescence intensity (MFI) of the far-red channel for each cell, representing Anti-Neuroligin-3 [IPI-mNLGN3.3] labeling, was recorded. Each histogram displays the number of cells with MFIs ranging from below 100 (background fluorescence) to 4095 (saturation).
Controls
Positive control (not shown): Anti-V5 [IPI-SV5-Pk1] (Addgene #218107) used to confirm IF labeling efficacy (since construct expressing target also has a V5 tag).
Negative control (not shown): Rabbit IgG used to confirm transfected construct does not interact /produce signal with every antibody.
Results

- Pass (The antibody worked under these conditions)
- Describe Results
- This data shows binding to human and mouse NLGN3 only.
