Abstract: Experimental results for Anti-IGDCC3 (PUNC) [IPI-mIGDCC3.13] (Addgene #241897) in an immunofluorescence (IF) binding assay with ExpiCHO cells expressing V5-tagged human or mouse IGDCC3.

**Caption:** A) Immunofluorescence (IF) of ExpiCHO cells transfected with human (top) and mouse (bottom) IGDCC3 and labeled with Anti-IGDCC3 (PUNC) [IPI-mIGDCC3.13] (Addgene #241897). Left images show all three channels (IPI-mIGDCC3.13, GFP (transfection control) and DAPI) while the right images only show IPI-mIGDCC3.13 and DAPI. Images taken at 40X magnification. B) Combined quantification of multiple images of the same transfected cells taken at 10X magnification. IPI-mIGDCC3.13 labeling of human (left) and mouse (right) IGDCC3 is shown in the top row, and compared to a positive (left) and negative (right) control in the bottom row. For both panels, IPI-mIGDCC3.13 was used at 1 μg/mL (1:1000 dilution).

Additional Information

Additional Information

Confocal images taken at 40X magnification on an EVOSm7000 microscope and deconvolved using the Lucy-Richardson algorithm.

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-mIGDCC3.13 labeling, was recorded. Each histogram displays the number of cells with MFIs ranging from below 100 (background fluorescence) to 4095 (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 and mouse IGDCC3.
