LLC cells treated with IKKβ shRNA or control shRNA were plated on coverslips coated by laminin in a 24-well plate. After incubation for 36 hours, the cells were fixed with 4% paraformaldehyde and washed three times in PBS.

HeLa cell monolayers grown on coverslips infected by C. muridarum transformants were fixed with 4% paraformaldehyde for 45 min at room temperature and permeabilized with 2% saponin for an additional 60 min. After blocking, the cell samples were incubated with mouse anti-Pgp3 or GlgA antibody, rabbit antichlamydial organism antibody, and Hochest (to mark DNA) overnight at 4°C. A goat anti-rabbit IgG secondary antibody conjugated with Alexa Fluor 488 and a goat anti-mouse IgG conjugated with Cy3 (Jackson ImmunoResearch, West Grove, PA) were used to incubate the cell samples at room temperature for 1 h. Immunofluorescence images were acquired using an immunofluorescence scanning microscope (Zeiss, Germany).

HeLa 229 monolayers cultured on coverslips were infected with C. muridarum strain Nigg and processed for antibody staining as described previously (19 (link), 20 (link)). Infected cells were fixed with 2% paraformaldehyde for 30 min and permeabilized with 1% saponin (Sigma-Aldrich) for 45 min at room temperature. After blocking, Hoechst staining solution (blue; Sangon Biotech Co., Ltd.) was used to visualize DNA. A genus-specific rabbit antibody against chlamydial EBs and Cy2 (green; Jackson ImmunoResearch Laboratories, Inc., West Grove, PA, USA)-labeled goat anti-rabbit IgG secondary antibody were used to visualize the chlamydial inclusions. Antisera collected from each immunized mouse group and Cy3 (red; Jackson ImmunoResearch Laboratories, Inc.)-conjugated goat anti-mouse IgG secondary antibody were used to visualize the Pgp3 antigen. All images were obtained using an AX-70 fluorescence microscope (Olympus, Melville, NY, USA).

Approximately 2 × 106 U2OS cells expressing or not PIKfyve or PIKfyveKYA were collected and sonicated to extract total proteins. 100 µg of total proteins was then subjected to electrophoresis in 4–12% Bis-Tris Plus Gels (Novex, NW00125BOX) and transferred onto PVDF membrane using a Trans-Blot Turbo Transfer System (Bio-Rad). After blocking with 5% non-fat milk, PVDF membrane was incubated at 4°C with 1:1000 ratio of PIKFYVE antibody (Invitrogen, PA5-13977) or 1:1000 ratio of α/β-tubulin antibody (Cell Signaling, 2148). Both primary antibodies were probed using goat anti-rabbit IgG secondary antibody conjugated with horseradish peroxidase (Jackson ImmunoResearch, West Grove, PA) and visualized by chemiluminescence (SuperSignal West Pico Chemiluminescent Substrate, Thermo Fisher). Images were obtained using an Odyssey FC Imager (Dual-Mode Imaging System; 2 min integration time).

U-2 OS cells were electroporated with plasmids encoding endoplasmic reticulum marker mEm-Sec61B (gift from Michael Davidson; Addgene plasmid # 54249). Samples were processed similarly to samples labelled only for mitochondria 25 (link) with the following changes: the cells were labeled with mouse anti-GFP primary antibody (Invitrogen, A-11120) at 1:100 and rabbit anti-TOM20 (Abcam, ab78547) at 1:500 overnight at 4°C. After washing, the samples were labeled with goat anti-mouse IgG secondary antibody (Jackson ImmunoResearch, 115-005-146) and goat anti-rabbit IgG secondary antibody (Jackson ImmunoResearch, 111-005-144) conjugated with oligonucleotide docking strands (Ext. Data Fig. 1, D1-1c and D2-1a, respectively) both at a concentration of 1:200 for 1 hr at room temperature.

All of the tissues or cells were lysed in RIPA buffer, and their total protein concentrations were determined with a BCA protein assay kit. The total protein was loaded into precast 10% SDS-PAGE gels, and then the target protein was transferred to PVDF membranes. The membrane was blocked in 5% milk for 1 h and washed once with Tris-buffered saline with Tween-20 (TBST). After that, the membranes were incubated at 4 °C overnight with the following primary antibodies: anti-β-actin (Servicebio, GB11001, 1:5000), anti-Drp1 (Abcam, ab184247, 1:2000), anti-Mfn2 (Abcam, ab124773, 1:2000), and anti-Opa1 (Proteintech, 27733-1-AP, 1:2000). The primary antibodies were recycled and the membranes were washed 3 times in TBST for 6 min each. Goat anti-Rabbit IgG secondary antibody (Jackson ImmunoResearch, 103069, 1:5000) was incubated for 1 h at room temperature. After removing the secondary antibody, the membranes were washed 3 times with TBST for 6 min each. Finally, the levels of the relative proteins were detected using an enhanced chemiluminescence reagent. The signals were confirmed with a band intensity analysis using Image J software.

DNA-antibody conjugation protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
Both the “imager” and the “docking” strands (nucleotide sequence and terminal modifications specified in Table S1) were commercially synthesized by Eurofins UK. The two nucleotide designs of the P1 and P3 sequences were obtained from Jungmann et al. (2014) (link). We opted for a direct thiolation to link a 5′ C6 amine of the docking strands and cysteines of the antibody. Respective docking strands were conjugated to either a goat anti-mouse immunoglobulin G (IgG) or a goat anti-rabbit IgG secondary antibody (Jackson ImmunoResearch, PA) or a primary antibody against RyR2, clone C3-33, using a Thunder-Link kit (Innova Biosciences, Cambridge) and spectrophotometric analysis to ensure an oligo: antibody conjugation ratio ≥1:1.

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.
