![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-NTN1 [IPI-NTN1.45] (Addgene #259427) labeling, was recorded. 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-NTN1.45 was used at 1 µg/mL (1:1,000 dilution).](https://datahub-media.addgene.org/report-images/372m9s/NTN1.45_IFSpecificity.png)

Sample
- Target Species
- Human
- Cell / Tissue Type
- ExpiCHO
- Additional Information
- ExpiCHO cells were transiently transfected with human NTN1, or human or mouse NTN3, or NTN4. Human targets were cotransfected with GFP and mouse targets were cotransfected with BFP (transfection controls).

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-NTN1 [IPI-NTN1.45] labeling, was recorded. Each histogram displays the number of cells with MFIs ranging from below 100 (background fluorescence) to 25000 (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 Isotype Control [IPI-MOPC-21] (Addgene #237822) used to confirm lack of nonspecific binding to the sample.
Results
