Embryos were fixed in 4% paraformaldehyde in PBS, cryoprotected in 30% sucrose in PBS and subsequently stored at -80°C. Sagittal sections (16 μm) were cut on a cryostat, after which they were washed with PBS and blocked in 4% Fetal Calf Serum (FCS) in THZT (50 mM Tris-HCl pH 7.6, 0.5 M NaCl, 0.5% Triton) or PBS-T (0.5% Triton).

Lung samples from untreated (negative control) and LV-treated mice were fixed in 4% paraformaldehyde, paraffin-embedded, sectioned at 5 µm, and de-paraffinised using standard histological procedures. Antigen retrieval was performed using 0.1 M EDTA (pH 8.0) for 10 min followed by permeabilisation in phosphate-buffered saline (PBS)/Triton X-100 (0.3%) for 10 min. Sections were blocked for 1 h at room temperature in a solution of 1% bovine serum albumin and 0.05% Tween-20. Primary antibody chicken α-GFP (1:100 dilution) (Abcam, ab13970) was resuspended in blocking buffer and incubated with samples overnight at 4 °C. No antibody and secondary antibody-only controls were included. Slides were washed followed by incubation with goat α-chicken Alexa Fluor® 568 (1:200) (Abcam, ab175711) in blocking buffer at room temperature for 1 h. Samples were washed followed by counterstaining with DAPI (1 µg/mL) and mounting with ProLong Diamond Antifade Mountant (Molecular Probes). Images were generated using an Olympus FV3000 confocal microscope.

Adult females were aged 3 days on yeast at 25°C and dissected in S2 media. Ovaries from 25 females per genotype were collected and lysed in cold modified RIPA buffer (50mM Tris pH 7.8, 100 mM NaCl, 2 mM CaCl2, 0.1% SDS, 0.5% Sodium Deoxycholate, 1% triton) + complete protease inhibitor cocktail (Roche) by manual grinding and passage through a 27-gauge needle. Lysate was centrifuged at 13000 RPM and supernatant collected. GFP immunoprecipitation reactions were performed using GFP-Trap beads (Chromotek) at 4°C overnight. Input lysate and immunoprecipitate were analyzed via Western Blot on a 4–15% Mini-PROTEAN TGX Gel (Bio-Rad) using the following antibodies: rabbit α-SPARC (1:1500) (Martinek et al., 2002 (link)), chicken α-GFP (1:10,000, abcam). IRDye (LI-COR) secondary antibodies were used at 1:5000. Blots were imaged with Odyssey software version 2.1 (LI-COR Biosciences).

Acetylated Histone Detection Protocol

Whole worm lysates were prepared from young adult worms (24 hours post-L4) by freezing and then boiling the worms in Laemmli sample buffer. Proteins were resolved by SDS-PAGE and then transferred onto polyvinylidene difluoride membranes (Millipore, 0.2 μm pore size) in transfer buffer (25 mM Tris-HCl pH 8.3, 192 mM glycine, 20% (v/v) methanol and 0.1% (w/v) SDS). The presence of SDS ensures histones can be completely transferred onto the membrane. Antibodies were used at the following dilutions: chicken α-GFP (Abcam, 1:2000), mouse α-HA (Sigma, 1:2000), rabbit α-AcK (1:3000), rabbit α-H3ac (Active motif, 1:3000), rabbit α-H4ac (Active motif, 1:3000), rabbit α-H3 (Cell signaling, 1:5000), rabbit α-H3K56ac (Millipore, 1:3000), mouse α-tubulin (Sigma, 1:2000), rabbit α-ACER-1(1:3000). Horseradish peroxidase-conjugated secondary antibodies from Jackson ImmunoResearch Laboratories were used at a 1:5000 dilution. Specific proteins were visualized with Pierce ECL Western Blotting Substrate. The relative level of acetylated histones was determined by densitometric analysis of the western blot bands (AcK relative to H3) using ImageJ software.

To generate Drosophila neuroblast MARCM clones, FRT-G13, aPKCK06403/CyO Virgin flies were crossed to ;;3xHA-aPKC V606A male flies. The resulting non-Cyo male progeny were crossed to elav-Gal4, UAS-mCD8:GFP, hs:flp; FRT-G13, tubPGal80 Virgins and allowed to lay for 24 hours at room temperature. The vials were then allowed to stay at room temperature for an additional 24 hours at which time they were heat-shocked @37°C for 90 minutes. This was followed by a possible second 90 minute heat-shock within 18 hours. Vials were raised at 18°C or room temperature until wandering third instar stage when they were dissected and stained as described above with the following antibodies: Primary antibodies: Rat α-Mira (1:500; Abcam, ab197788), Rabbit α-HA C29F4(1:1,000; Cell Signaling Technologies, 3724) or Mouse α-HA (1:500; Covance, MMS-101P), and Chicken α-GFP (1:500; Abcam, ab13970).

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.
