All stocks were cultured on standard molasses/maize meal and agar medium in plastic vials or bottles at 25°C. Larvae were reared on apple juice plates supplemented with molasses/maize meal and yeast as previously described [79 (link)]. Larvae were selected for NMJ analysis at 5 days post egg laying. For analysis of bouton number was performed on the NMJ innervating muscles 6 and 7 from hemisegment A2 (1). Over 15 larvae were analysed for each genotype. For immunohistochemistry larvae were fixed for 20mins in 4% paraformaldehyde, or Bouin’s fixative for 30 minutes (GluRIIA). Primary antibodies used were anti-discs large (DLG, Developmental Studies Hybridoma Bank (DSHB), Iowa City, Iowa, USA),anti-Fas2 (DSHB), anti-GluRIIA (DSHB) and anti-BRP (DSHB), all used at 1/100. Secondary antibodies used were AlexaFluor 488 goat anti-rabbit and AlexaFluor 633 goat anti-mouse (Invitrogen) at 1/1000, and anti-HRP-TRITC (The Jackson Laboratory, Bar Harbor, Maine, USA). Z-stacks were taken using a laser-scanning confocal microscope (Leica TCS SP5 II confocal microscope) and analysis performed using ImageJ and Adobe Photoshop. For statistical analysis of the genetic interactions, ANOVA was performed between the control, the two single heterozygous mutations and the transheterozygotes.

Dissected ovaries and reproductive tracts of sacrificed adult female mice were fixed in 4% paraformaldehyde in PBS for 20 min and cryoprotected in 20% sucrose in PBS. Tissue sections with a thickness of 10 μm were cut from frozen specimens embedded in tissue freezing medium Jung (Leica Microsystems). Cryosections were mounted on Superfrost plus slides (Thermo Scientific), dried overnight, permeabilized with 0.1% Triton X-100 in PBS for 20 min and blocked for 60 min at room temperature with 1% BSA and 5% goat serum in PBS. Proteins were revealed by incubation with rabbit polyclonal anti-RIC8 (1:70, Proteintech Group, Inc) and anti-beta tubulin antibody (1:100, E7, Developmental Studies Hybridoma Bank) overnight at 4°C followed by Alexa Fluor 594 goat anti-rabbit (1:600, Invitrogen) or Alexa Fluor 633 goat anti-mouse (1:600, Invitrogen) secondary antibody for 60 min at room temperature. Cell nuclei were counterstained with DAPI and specimens mounted in Fluoromount G (Electron Microscopy Science). For negative controls, primary antibodies were omitted and no staining was observed.

All the incubation steps in this staining protocol are performed on a plate shaker (at 30 rpm) unless stated otherwise. Encapsulated cells in 3D gels are washed twice with PBS for 30 minutes and are fixed with 4% paraformaldehyde (PFA) in PBS for 1 h on a plate shaker. After fixing, the gels are washed twice with PBS for 1 h and treated with 0.1% TritonX-100 for 40 minutes, and further washed twice with PBS for 1 h. For L929 fibroblasts, the gels are treated with iFluor-phalloidin 488 or 594 (Abcam, Germany) (1:1000) in PBS in combination with DAPI (1:100) and incubated for 4 h. The gels are washed twice with PBS for 1 h each and stored until imaging. The encapsulated DRGs in the gel are blocked with 5% bovine serum albumin (BSA) (Sigma, Germany) in PBS for 4 h, followed by the addition of primary beta-tubulin antibody TUJ1 (BioLegend, USA) (1:250) in 5% BSA solution for 18 h. The gels are washed twice with PBS for 1 h before adding the secondary antibody Alexa Fluor 633 goat anti-mouse (Invitrogen, Germany) (1:1000) in PBS and DAPI (1:100). The secondary antibody solution is incubated for 4 h and washed twice for 1 h each and stored in PBS until imaging with confocal microscopy.

The sections were boiled for 3 min in citrate buffer (10 mmol/L, pH 6.0) at 95 °C to unmask epitopes, followed by blocking with 1% (w/v) bovine serum albumin (in PBS with 0.01% (v/v) Tween 20) for 30 min. Primary and secondary antibodies were diluted in PBS containing 0.02% (v/v) Triton X-100 and 0.02% (v/v) Tween 20. Between every protocol step, slides were washed in PBS 0.02% (v/v) and Tween 20 three times for 5 min. After application of the primary antibody DNA/RNA Damage Ab (15A3) (NB110-96878SS) (1:1000) overnight at 4 °C, sections were incubated for 1 h with the secondary antibody (1:500, AlexaFluor®633 goat anti mouse, Invitrogen, Paisley, UK) at room temperature. Finally, the slides were mounted with fluorescent-free mounting medium (Prolong Gold antifade reagent, P36930, Life Technologies, UK). Maximal intensity projections were obtained with an inverted Zeiss LSM confocal microscope using Axiovision 4.8.2 SP 3 software with same settings for each slide.

Larvae were reared and dissected, as previously described (54 ), and at least 20 NMJs (muscles 6–7, hemisegment A2) per genotype per stage were scored (55 (link)). For immunohistochemistry, anti-discs large (DLG, DSHB, 4F3), anti-HRP (Jackson Immuno, 323-005-021), anti-bruchpilot (DSHB, nc82) and anti-HA (Santa Cruz, sc-805) were all used at 1/100, with AlexaFluor 488 goat anti-rabbit and AlexaFluor 633 goat anti-mouse (Invitrogen) secondary antibodies at 1/1000. Z-stacks were taken using a Leica SP5 laser confocal microscope and analyses performed using ImageJ and Photoshop (Adobe). For BRP analysis in the axon, optical sections of 0.2 µm were taken using a laser-scanning confocal microscope (Leica TCS SP5 II confocal microscope). Bouton size analysis was performed by averaging two perpendicular diameter measurements of individual Ib boutons. All observable Ib boutons, which were identified by intense DLG staining, were measured per NMJ. All digital analyses and fluorescence measurements were performed using ImageJ. For BRP and HA staining at the synapse, average fluorescence intensity was analysed over the whole synapse (marked by HRP staining), again using optical sections of 0.2 µm. For HA staining, this was normalized to the background fluorescence intensity in the muscle.

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.
