Check if the same lab product or an alternative is used in the 5 most similar protocols
Western blot using BmN4 cell lysates was performed as described previously36 (link). Cell lysates were prepared from identical number of the cells from respective density conditions in a lysis buffer containing 20 mM Tris-HCl pH 7.4, 200 mM NaCl, 2.5 mM MgCl2, 0.5% NP-40, 0.1% Triton X-100, and complete protease inhibitor (Roche Diagnostics). After quantifying protein concentration of the lysates, 20 μg of each lysate was loaded onto SDS-PAGE. The following antibodies were used: S213 anti-Siwi36 (link), anti-BmAgo323 (link), anti-Tom20 (Santa Cruz Biotechnology), anti-Hsp60 (Cell Signaling), anti-β-actin (Abcam), anti-BmPapi10 (link), and BmVasa571 anti-BmVasa53 . The anti-BmVasa is able to specifically recognize BmVasa in Western blot and immunofluorescence (Supplementary Fig. S1). The Western blot band intensities showed clear linearity to the amount of lysate input (2.5–20 μg), suggesting the quantification ability of the Western blot analyses (Supplementary Fig. S2).

Urothelial cells were intracellularly infected at an MOI 5–10 or mock infected as described above. Cells were washed in PBS and fixed in 4% paraformaldehyde for 20 minutes at room temperature followed by permeabilization in 1% Triton-X-100 for 5 minutes at room temperature. After blocking in 10% BSA, immunostaining was performed with anti-HSP60 (1:200; Cell Signaling Technologies; 12165S) and anti-rabbit IgG Alexa Fluor 546 (1:500; Thermo Fisher Scientific; A10040). Super-resolution mitochondrial images were acquired using a Nikon SIM microscope equipped with a 1.49 NA 100x Oil objective and Andor DU-897 EMCCD camera. Quantification of mitochondrial morphology was performed in NIS-Elements (Nikon) as described previously59 (link). Mitochondria were segmented in 3D and skeletonized using the resulting binary 3D mask. All mitochondria within each cell were averaged resulting in one data point per cell. Acquisition and analysis of mitochondrial imaging data was performed by a blinded experimenter.

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.
