Human/Mouse/Rat Netrin-1 Antibody

Detection of Human, Mouse, and Rat Netrin‑1 by Western Blot. Western blot shows lysates of IMR-32 human neuroblastoma cell line, bEnd.3 mouse endothelioma cell line, and C6 rat glioma cell line. PVDF membrane was probed with 0.5 µg/mL of Sheep Anti-Human/Mouse/Rat Netrin-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6419) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Netrin-1 at approximately 66 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Detection of Mouse Netrin-1 by Western Blot MiDAC regulates neurite outgrowth via the SLIT3/ROBO3 and NTN1/UNC5B signaling pathways.(A) WB for signaling components of the SLIT3/ROBO3 and NTN1/DCC/UNC5B signaling axes from CM and total cell lysates of WT and Dnttip1 KO1 NE after 12 days of differentiation. To enrich SLIT3 and NTN1 from CM, IPs were performed with SLIT3 and NTN1 antibodies from CM of WT and Dnttip1 KO1 NE. Actin is the loading control for the total cell lysates. (B) Assay to rescue the neurite outgrowth defects in Dnttip1 KO1 NE. CM of Dnttip1 KO1 NE was supplemented with the recombinant signaling ligands SLIT3 and/or NTN1 from day 7–12 without or with preblocking of Dnttip1 KO1 NE with IgG or signaling receptor antibodies against ROBO3 and/or UNC5B. MAP2 IF staining was performed after 12 days of differentiation. Nuclei were stained with DAPI. To facilitate analysis the neuronal cell body (blue) and its neurites were manually traced with ImageJ software and for each sample one traced neuron is displayed in the inlet. The white scale bar represents 50 µm. (C, D) Quantification of (C) neurite length and (D) the total number of neurites per neuron from the MAP2 IF staining in (B) using ImageJ. (C) Neurite length was divided into two categories of short neurites <50 µm (green box plots) and longer neurites ≥50 µm (white box plots). (C, D) The neurites of 200 neurons were assessed per sample. One-way ANOVA was performed throughout where ***, p≤0.001; and ns, p>0.05 is not significant.MiDAC regulates neurite outgrowth via the SLIT3/ROBO3 and NTN1/UNC5B signaling pathways.(A) Chamber assay to rescue the network formation defects of GNP-derived neurons that were supplemented with CM of Dnttip1 KO1 NE. CM of Dnttip1 KO1 NE was supplemented with the recombinant signaling ligands SLIT3 and/or NTN1 from day 7–12 without or with pre-blocking of GNP-derived neurons with control IgG or signaling receptor antibodies against ROBO3 and/or UNC5B. TUBB3 IF staining was performed after 12 days of differentiation. Nuclei were stained with DAPI. The white scale bar represents 100 µm. (B) Quantification of neuronal network formation from the TUBB3 IF staining in (A) using ImageJ. The percentage of formed neuronal networks within the total population of TUBB3-positive neurons is displayed. A neuronal network was scored when a closed local circuit was detected around an individual neuron. Neuronal network formation was assessed for 100 neurons per sample in triplicate. Unpaired t-test was performed throughout where ***, p≤0.01.
