Third-instar larvae were dissected, fixed in Bouin’s fixative or 4% PFA in PBS, and immunostained as previously described (Eaton et al., 2002 (link); Harris et al., 2015 (link)). Dissected third instar larvae were fixed with PFA (4%) and incubated overnight at 4 C with primary antibodies (mouse anti Flag 1:50; rabbit anti-RFP 1:100; rabbit anti-Dlg, 1:1000; anti-Syt1 1:1000, anti-Brp 1:100, Life Technologies). Alexa-conjugated secondary antibodies and goat anti-HRP were used (Jackson Laboratories 1:500). Images were acquired with either a Zeiss LSM700 confocal microscope equipped with Zen software using a 63X 1.6 NA oil immersion objective or an upright epifluorescence deconvolution confocal microscope (Axiovert 200, Zeiss) equipped with a 100X objective (N.A. 1.4), cooled CCD camera (CoolSnap HQ, Roper Scientific). Slidebook 5.0 (3I, Intelligent Imaging) was used for capturing, deconvolving and analyzing images. Structured illumination microscopy (Nikon LSM 710 equipped with 63X objective and Andor Ixon EMCCD camera) was used to perform Brp-GFP and MCTP-Flag colocalization experiments. Bouton numbers and Brp numbers and densities were quantified as described previously (Harris et al., 2015 (link)).

Neuronal Morphology of NRXN1+/- hiPSC-Neurons

Check if the same lab product or an alternative is used in the 5 most similar protocols
Unlabeled control hiPSC-NPCs were plated onto 24-well matrigel coated plates with coverslips. Control hiPSC-NPCs were transduced with a scramble_gRNA-eGFP-puro expressing lentivirus while NRXN1+/− hiPSC-NPCs were transduced with scramble_gRNA-tdTomato-puro expressing lentivirus. A small number of control tdTomato labeled and NRXN1+/− eGFP-labeled hiPSC-NPCs were spiked into the unlabeled background of hiPSC-NPCs upon plating. hiPSC-NPCs were then differentiated for 6 weeks into hiPSC-neurons and immunostained using mouse anti-GFP (ThermoFisher), 1:1,000; rabbit anti-RFP (ThermoFisher) 1:1,000; with Alexa donkey anti-mouse-488 and Alexa donkey anti-rabbit-568 secondary antibodies as described above. Individual neurons were imaged at 20x on the Zeiss 780 upright confocal microscope, followed by tracing and analysis using ImageJ Simple Neurite Tracer Plugin. One-way ANOVA with Dunnett’s test was used to test the impact of genotype on neuronal morphology. As only the eGFP 3’-NRXN1+/− were imaged on the same coverslip as tdTomato labeled controls, we assess the impact of coverslip to coverslip variation between these lines using a two-way ANOVA.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
