Quantification of NET Formation

NET formation was monitored by the presence of extracellular DNA covered with MPO. Cover glasses (CS) were coated with fibronectin (2.5μg/ml, Sigma-Aldrich) for 1h. 3x104 freshly isolated PMNs were resuspended in 30μl of RPMIΔ (RPMI 1640 GlutaMAX without supplements), seeded on CS and allowed to adhere for 20min. 20μl of medium containing either medium alone, DMSO, 100nM PMA or different amounts of HIV-1 viral particles were added to the CS and cells were incubated for 3 or 24h at 37°C, 5% CO2. Cells were then fixed with 3% PFA for 90min at room temperature, permeabilized with 0.1% Triton X-100 and stained with anti-human MPO (1:100, clone 2C7, Abcam) followed by Alexa Fluor 568 goat anti-mouse antibody (1:2000, Life Technologies). Cells were additionally stained with Hoechst 33342 (1:10000, Invitrogen).
Quantification of NET formation was performed as follows: 5 random sections on the CS were imaged. Cells were divided in three categories: lobular nucleus, round nucleus and NET forming cell. The cells were attributed to one of the categories, counted manually and the percentage was calculated. NET formation in PMA treated samples was artificially set to 100% since the entire CS was covered with NETs which did not allow distinction.

E-cadherin Perturbation and Focal Adhesion Visualization

Check if the same lab product or an alternative is used in the 5 most similar protocols
In experiments where antibodies were used to perturb E-cadherin-mediated cell–cell adhesions, MCF10A-E-cadherin-GFP cells were treated with 3 µg/ml of neutral, control antibody (76D5; gift of BM Gumbiner (Petrova et al., 2012 (link))), or E-cadherin-blocking antibody (DECMA-1; Abcam) for at least 2 hr prior to TFM measurements. As an additional control, cells were also imaged and measured pre-treatment.
In immunostaining experiments to visualize focal adhesions in MCF10A-E-cadherin-GFP cell clusters, a purified mouse anti-paxillin antibody (BD Biosciences, San Jose, CA) was used as the primary antibody and the Alexa Fluor 568 goat anti-mouse antibody (Life Technologies, Grand Island, NY) was used as the secondary antibody.

Frozen testis sections (10 μm) from 3- to 4-month-old Bscl2+/+ and Bscl2−/− males (N=4) were used for detecting the expression of vimentin, PRM1, and PRM2 following the procedure as described previously.49 (link) Sections were incubated with vimentin antibody (1:50 dilution, sc-373717, Santa Cruz Biotechnology) or PRM1 antibody (1:100 dilution, 21 μg/ml, Hup1N, Briar Patch Biosciences, Livermore, CA, USA), or PRM2 antibody (1 : 100 dilution, 21 μg/ml, Hup2B, Briar Patch Biosciences) overnight at 4 °C. Vimentin, PRM1, and PRM2 signals were detected by incubating with Alexa Fluor 568 goat anti-mouse antibody (1 : 200 dilution, Life Technologies) for 30–60 min at room temperature. Testis sections were counterstained and mounted in DAPI-containing Vectashield (Vector Laboratories). Two types of negative control were used: sections of 3-month-old Bscl2+/+ males incubated with mouse IgG (1 : 100, Santa Cruz Biotechnology) or without any primary antibody. All other procedures were the same as described above. In addition, PRM1 and PRM2 were also detected in the sperm spreads from Bscl2+/+ and Bscl2−/− males (4 months old, N=3) using the same condition as for testis sections.

Immunostaining of EBs was carried out as previously described (22 (link)). Briefly, EBs were fixed and dehydrated with 4% Paraformaldehyde (PFA) and followed by sequential Sucrose incubation. After cryo-embedding, 7 μm-thickness of sectioning was performed with a cryostat microtome (Leica, Vetzlar, Germany). For immunostaining, EB sections were fixed with 4% PFA for 15 min, permeabilized with 0.5% Trinon X-100 for 5 min, blocked with 3% BSA for 30 min and probed with the following antibodies; Nkx6.1 (F55A12, DSHB, Iowa, USA, 1:300), Olig2 (ab109186, Abcam, UK, 1:300), Islet1 (Isl1) (ab20670, Abcam, 1:300) or Hb9 (PA5-23407, Invitrogen, Massachu-setts, USA, 1:300). After over-night incubation with primary antibodies at 4℃, cells were labeled with appropriate secondary antibodies (Alexa Fluor 488 goat anti-rabbit or Alexa Fluor 568 goat anti-mouse antibody (Life technologies, California, USA, 1:300). Cells were counterstained with 4’,6-diamidine-2-phenylindole dihydrochloride (DAPI, Roche) to show the nuclei. Confocal images were obtained with a LSM-710 Meta confocal fluorescence microscope (Carl Zeiss, Oberhochen, Germany).

The primary antibodies used were mouse anti-Chaoptin (MAb24B10) (1:100, DSHB #24B10, Iowa, IA, USA), mouse anti-22C10 (1:100, DSHB #22C10, Iowa, IA, USA) and rabbit anti-GFP (1:1000, ThermoFisher Scientific #A11122, Waltham, MA, USA), while the secondary antibody were Alexa Fluor 568 goat anti-mouse antibody (1:1000, ThermoFisher Scientific #A11031, Waltham, MA, USA) or Alexa Fluor 488 goat anti-rabbit antibody (1:1000, ThermoFisher Scientific # A11008, Waltham, MA, USA).
The brains of three-to-five-day-old mtt-Gal4 > UAS-mCD8::GFP flies were dissected with their retina preserved. At first, the whole flies were fixed in 4% formaldehyde at 25 °C for 2 h. Then, the dissected brains were washed in PBT (PBS containing 0.2% Triton X-100) and blocked in 5% goat serum in PBT (PBST) for 30 min at room temperature. The primary antibodies were used to incubate the samples overnight at 4 °C. Finally, samples were washed three times with PBT and incubated overnight with Alexa Fluor 488-labeled goat anti-rabbit or Alexa Fluor 568-labeled goat anti-mouse secondary antibody overnight at 4 °C. Images of mounted samples were captured under confocal microscope (Leica TCS SP5, Wetzlar, Germany).

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.
