2026-02-16 Monday

Flipping

Flies at +29°C (luc-RNAi, GLO1-OE, cellfate) were flipped and put back at +29°C.

Sorting

RedDM and cellfate lines (2) were sorted and put in new holidic tubes at +18°C.

Crosses ReDDM - PWP1/smoothened

Crosses were made with around 20-25 virgins of the driver and 10-12 males of the other line:

Esg-Gal4, UAS-GFP / CyO ; Tub-Gal80ts, UAS-RFP / Tm6b > OregonR
Esg-Gal4, UAS-GFP / CyO ; Tub-Gal80ts, UAS-RFP / Tm6b > smo-RNAi (#27037)
Esg-Gal4, UAS-GFP / CyO ; Tub-Gal80ts, UAS-RFP / Tm6b > UAS-smo (#44622)
Esg-Gal4, UAS-GFP / CyO ; Tub-Gal80ts, UAS-RFP / Tm6b > PWP1-RNAi
Esg-Gal4, UAS-GFP / CyO ; Tub-Gal80ts, UAS-RFP / Tm6b > UAS-PWP1

Crosses EsgFO - Hh sensor_p4EBP

Crosses were made with around 20-25 virgins of the driver and 10-12 males of the other line:

Esg F/O > ptc-lacZ / CyO ; PWP1-RNAi / (Tm2)
Esg F/O > ptc-lacZ / CyO ; Luc-RNAi / (Tm2)

Virgin sorting

Virgin sorting of esgF/O at around 14h30 and IF / CyO, GFP ; Bm×Δ2B / Tm3, GFP. For the esgF/O, flies were put back at +18°C. For the latter, non-virgin flies were put back in 2 new tubes at room temperature.

2026-02-17 Tuesday

Intestine staining protocol:

Day 1

  1. Dissect guts in PBS at RT°C (or in ice if staining for e.g. P-H3).
  2. Fix 2h in 8% PFA at RT°C, no shaking. prepare BSA during that time
  3. Coat a pipette tip in PBT by pipetting up and down. Use this emptied tip to take off the PFA. (the guts might stick to the tip if not coated)
  4. Rinse 1× with PBT
  5. Block 30 min in 1% BSA in PBT, shaking.
  6. Add Primary antibodies in 1% BSA in PBT overnight at +4°C, shaking.

Day 2

  1. Rinse 2× + wash in PBT, shaking, while preparing the 2nd antibody.
  2. Add secondary antibodies in 1% BSA in PBT for 1h (30 min if in a rush) at RT°C, shaking.
  3. Rinse 2× and leave washing for 3-4h at RT°C in PBT.
  4. Remove the PBT and add Vectashield + DAPI mounting media 30 µL.

Few days prior to imaging

  1. Mount on slides with slightly indented circles to avoid coverslip crushing

Example primary antibodies

Dilute secondary antibodies 1:1000

With samples that don’t need antibodies, skip steps 4-8.

Dissection & Staining

Dissection of Luc-RNAi and GLO1-OE lines that were at +29°C, respectively 12 and ~10 guts. They were put in PFA for 2 hours. Preparation of 1% BSA in PBT: 0.5164 g of BSA and 5,100 µL of PBT (PBS + 0.1% Triton X -100). This was in fact 10% BSA in PBT so the proper one was made with 0.0390 g of BSA and 5,000 µL of PBT. The rest of the protocol for the day was followed correctly. Incubation was done with 1:1000 anti-prospero (1 µL anti-prospero antibody with 1 mL BSA 1%) overnight at +4°C.

Transfer RedDM at +29°C

RedDM (RedDM > OregonR and RedDM > PWP1-RNAi) flies at +29°C (put there the 2026-02-13) were flipped in new holidic tubes.

Pupae collection

New redDM pupae were collected in holidic tubes ((6)th, collected on 2026-01-30), one for each (OregonR and PWP1-RNAi) and put at +18°C as a backup for the RedDM put today at +29°C. The rest of the tubes were trashed ((6)th after use, (7)th and (8)th) aswell as flies sorted on 2026-02-16.

2026-02-18 Wednesday

Staining

Following of the staining along the protocol, 1 µL of anti-mouse antibodies at 568 nm in 1mL of 1% BSA in PBT prepared the previous day. Rinses were done with 200 µL while the washings were done with 400 µL. Finally, after a 4 hour wash, guts were put in 30 µL of Vectashield + DAPI at +4°C.

Dana’s crosses - Virgin collection

As there was a lot of flies for the double balancer (If / CyO ; Sb / Tm6b), tubes were emptied at 14h. Flies were put in new tubes while the old tubes were kept for virgin collecting tomorrow.

2026-02-19 Thursday

Transfer RedDM from pupae

RedDM flies in holidic tubes where pupae had been transfered on 2026-02-17 were put in new holidic tubes without sorting them.

11h20 - Around 120 virgins of If / CyO ; Sb / Tm6b were collected and put at +18°C.

2026-02-20 Friday

Flipping

RedDM (RedDM > OregonR and RedDM > PWP1-RNAi) at +29°C were flipped in new holidic tubes and put back at +29°C.

9h50 - There are 6 males of pfk-RNAi (+ / + ; pfk-RNAi / pfk-RNAi) and 10 males of zw-RNAi (+ / + ; zw-RNAi / zw-RNAi). Therefore, the following crosses were realised with virgins from the collection of yesterday:

  2. female + / CyO ; pfk-RNAi / Tm6b × male + / If ; pfk-RNAi / Tm6b
  3. If / CyO ; pfk-RNAi / Tm6b (can be kept)
  4. female + / CyO ; pfk-RNAi / Tm6b × male UAS-SoNar / CyO ; Sb / Tm6b
  5. UAS-SoNar / CyO ; pfk-RNAi / Tm6b (can be kept)

  4. female + / CyO ; zw-RNAi / Tm6b × male UAS-iNap1 / CyO ; Sb / Tm6b
  5. UAS-iNap1 / CyO ; zw-RNAi / Tm6b (can be kept)

The step 4 is wrong, see here.

Dissection & Fixation

Dissection of RedDM > OregonR and RedDM > PWP1-RNAi flies along the protocol (without antibodies). Fixation of guts in 100 µL PFA. 3× rinces and wash in PBT, wash of 3h15 (shaking). Guts were finally put in 30 µL of Vectashield + DAPI at +4°C.

These new tubes were labelled with a (1)’. Females of the (1) tubes were put back in their original tubes. All tubes were stored at +25°C.

Flipping & Transfer at +25°C

Two y , w ; ptc-LacZ ; + tubes were flipped, original tubes were hydrated and put at +25°C while new tubes were put back at +18°C.

EsgF/O flies were flipped then transfered at +29°C. EsgF/O crosses were trashed except for Esg F/O > ptc-lacZ / CyO ; Luc-RNAi / (Tm2) (3). RedDM (4) were flipped into (5). EsgF/O flies from pupae (2) were transfered and sorted against CyO and (Tm2):

Transfer at +18°C

Tsc1-RNAi + PWP1-RNAi + ptc-lacZ (2) tubes as well as pfk/zw crosses (1) tubes realised on the 2026-03-13 were put at +18°C

Filtering

Previous filtering was redone with these values:

for 20260202.

for 20260209.

Additionally, filtering was realised for 20250218esgFO-boiPWP1_young:

2026-03-23 Monday

Tsc1-RNAi + PWP1-RNAi + ptc-lacZ

6 virgin female ptc-lacZ / Tsc1-RNAi ; + / Tm6b was collected for the step B. With the females collected previously (7 counting the one who died) and 4 males If / CyO ; Sb / Tm6b, the cross of step B was realised. The tube was put at +25°C.

Dana’s crosses - Combination

Final stock flies were collected for zw SoNar and zw iNap1 respectively:

These were put in a big tube for each genotype and at +18°C. (1) tubes realised on 2026-03-13 were transferred at +18°C.

RedDM & EsgF/O

Flies from pupae (2) EsgF/O were sorted against CyO and (Tm2), 4 females for Luc-RNAi and 2 for PWP1-RNAi, then added to the respective tubes which were flipped. 2 males were additionally added to Luc-RNAi tube. Pupae (2) were then trashed. EsgF/O flies at +29°C were flipped and put back at +29°C.

RedDM flies from pupae (2) and (3) were transferred without sorting in holidic tubes except for OregonR which was sorted against CyO: 17 females and 5 males.

Flipping

3.a.rd (2) was flipped into (3). Tubes (1)’’ for Dana’s crosses were flipped into (2)’’ and also put at +25°C. Tsc1-RNAi + PWP1-RNAi + ptc-lacZ (3) tube was flipped into (4), (3) and (4) tubes were transferred at +18°C. (2) tubes from step 4 of Dana’s crosses - Combination were flipped into (3).

Dissection & Fixation

Dissection of RedDM flies along the protocol (without antibodies). Fixation of guts in 60 µL PFA. 3× rinces and wash in PBT, wash of 3h15 (shaking). Guts were finally put in 30 µL of Vectashield + DAPI at +4°C.

2026-03-24 Tuesday

Tsc1-RNAi + PWP1-RNAi + ptc-lacZ

5 virgin female ptc-lacZ / Tsc1-RNAi ; + / Tm6b was collected for the step B. These flies were added to tube made yesterday.

Dana’s crosses - Combination

It turns out that the step 4 of the cross is wrong, the females need to be If / CyO ; pfk-RNAi / Tm6b instead of + / CyO ; pfk-RNAi / Tm6b. With this in mind, all step 4 and final stock already collected were trashed which leaves us with one tube of If / CyO ; pfk-RNAi / Tm6b and tubes of If / CyO ; zw-RNAi / Tm6b.

1 virgin female + / CyO ; pfk-RNAi / Tm6b was collected and added to the previous tube.

RedDM & EsgF/O

RedDM flies were transfered from pupae (2) and (3) without sorting.

Flipping

4.th (4)’ was flipped into (5)’. 1.st (5) was flipped into (6). 2.b.nd (5) was flipped into (6).

Filtering

Based on the previous filtering, an additional one was done without replacing the original with values specific for the GFP of the over-expressing condition (rest left unchanged):

Filtering for 20250218esgFO-boiPWP1_young that was done last time was also done with the same values but only for the END part.

Starved/Fed

From the EsgF/O tube that survived the trash, flies were transfered in a holidic tube and pupae in a starvation tube.
