Larvae were rinsed with 1% PBTx, (1% Triton X-100 in PBS), permeated in 0.24% trypsin in PBS and blocked for 3 hours in block buffer (10% normal goat serum (NGS) in 1% PBTx). Samples were incubated with anti-L-plastin [1:500 (V/V) dilution] in antibody buffer (PBTx containing 1% (V/V) NGS and 1% (W/V) BSA) overnight at RT. Samples were washed with PBTx, incubated for 1 hour in block buffer and stained with an Alexa-Fluor-647 goat-anti-rabbit antibody (Invitrogen A21070, 1:400), overnight at 4°C.

BMMs (1 × 105) were seeded in eight-well chamber slides (Thermo Fisher Scientific). After the treatment with different stimuli, cells were fixed with 4% paraformaldehyde and then permeabilized with 0.5% Triton X-100 for 15 min, followed by blocking with 1% bovine serum albumin and 0.1% Triton X-100 in phosphate-buffered saline (PBS) at 37 °C for 1 h. The samples were incubated with anti-ASC antibody (AL177, Adipogen), anti-ALIX antibody (634501, Biolegend), anti-CHMP4B antibody (13683-1-AP, Proteintech), and anti-LAMP1 antibody (1D4B, Developmental Studies Hybridoma Bank) in the blocking buffer overnight at 4 °C, followed by the incubation with Alexa Fluor 647 goat anti-rabbit antibody (A-21244, Thermo Fisher Scientific), Alexa Fluor 488 goat anti-rabbit antibody (A-11008, Thermo Fisher Scientific), or Alexa Fluor 568 goat anti-rat antibody (A-11077, Thermo Fisher Scientific) for 2 h at room temperature. Nuclei were stained with DAPI (H-1200, Vector Laboratories). To evaluate LAP formation, BMMs, generated from GFP-LC3 transgenic mice, were incubated with zymosan at a ratio of 8:1 (particle/cell), then GFP-LC3 puncta were detected. Images were acquired using a laser scanning confocal fluorescence microscope with a 60× objective (Olympus Fluoview FV3000).

After the glucose, glucagon or IBMX treatment, cells were rinsed with PBS and fixed with 4% paraformaldehyde for 15 min at room temperature. Then cells were incubated with the blocking solution (3% BSA in PBS) for 30 min at room temperature. Staining was performed incubating samples with the primary GCGR antibodies (2 μg/mL in 3% BSA) overnight at 4°C, and washed with PBS for three times. At last, samples were incubated with Alexa Fluor 647 goat anti-rabbit antibodies (2 μg/mL in 3% BSA; Thermo Fisher Scientific, A-21245) for 30 min at room temperature. After three washes, 50 μL imaging buffer containing Tris (50 mM, pH 8.0), NaCl (10 mM), glucose (10% w/v), glucose oxidase (500 μg/mL; Sigma), catalase (40 μg/mL; Sigma) and β-mercaptoethanol (1% v/v; Sigma) was dropped on a large microscope slide (24 mm × 50 mm, Fisher), and the small slide (22 mm × 22 mm, Fisher) where cells were seeded was covered on the large one and sealed with nail polish.

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.
