- Abstract
- Experimental results for Anti-Neurexin-1-Beta [N170A/1.1R] (Addgene #180100) in an immunocytochemistry assay with HeLa cells transfected with rat Nrxn1-Flag.
![HeLa cells transfected with rat Neurexin-1-beta-Flag were fixed and labeled with Anti-Neurexin-1-Beta [N170A/1.1R] (green; Addgene #180100) and Anti-DYKDDDDK [M2] - Chimeric (red; Addgene #198002). Nuclei were counterstained with DAPI.](https://datahub-media.addgene.org/report-images/joxmqi/Nxn1.png)

- Additional Information
HeLa cells were transfected with 0.1 µg of plasmid Nrxn-1 beta Flag/pCMV (Addgene #197339).
Cells were fixed and labeled 96 h later with antibodies against Neurexin-1-beta (Nrxn1; Addgene #180100) and Flag (Addgene #198002). Nuclei were counterstained with DAPI.
Permeabilization and blocking were performed with gentle agitation. Primary and secondary antibodies were diluted in PBS containing 0.3% Triton X-100 and 1% w/v BSA.
The secondary antibody used for detection of Anti-DYKDDDDK (Flag) was the goat anti-rabbit IgG (H+L) cross-adsorbed secondary antibody, Alexa Fluor 594 (Thermo Fisher, A-11012).
- Protocol
- Addgene immunocytochemistry protocol
- Controls
- Untransfected cells serve as the negative control and colocalization of the Nrxn1 and Flag signals in transfected cells serves as a positive control.
Results
- Result
- Pass (The antibody worked under these conditions)
- Describe Results
- Observed colocalization of the Nrxn1 (green) and Flag (red) signals in transfected cells, and no signal in the untransfected cells.
