Article Title: The nuclear envelope protein TMEM209 is an integral component of the nuclear pore complex and interacts with Nup210
Article Snippet: Protein samples were loaded on 4–12% NuPAGE Bis-Tris gels (Thermo Fisher Scientific) or 8% Bis-Tris gels (1.4 M Bis-Tris-HCl pH 6.8, 8% polyacrylamide) and separated via gel electrophoresis using NuPAGE ® 1× MES SDS running buffer or 1× MOPS (50 mM Tris-HCl pH 7.8, 50 mM MOPS, 0.1% SDS) running buffer with 200 mM Tris-HCl pH 9.0 anode buffer, respectively. .. Proteins were transferred to a PVDF membrane (Millipore) in a Mini Trans-Blot ® Cell (Bio-Rad) using transfer buffer (25 mM Tris, 0.193 M glycine, 0.02% SDS, 20% ethanol) for 90 min at 100 V or 16 h at 20 V. Membranes were blocked for 1 h at room temperature in blocking buffer [5% milk powder (Sigma-Aldrich) in TBS (24.8 mM Tris-HCl pH 7.4, 137 mM NaCl, 2.7 mM KCl)] and washed twice with TBS containing 0.01% (v/v) Tween 20 (TBS-T). ..

Article Title: Ribosomal RNA processing impairments in a B cell immunodeficient patient with WDR75 variants
Article Snippet: For northern blot analyses, RNAs were separated on a 1.1% agarose gel containing 1.2% formaldehyde and 30 mM triethanolamine, 30 mM tricine, pH 7.9 (3 μg total RNAs/lane), then transferred to a Hybond-N + nylon membrane (GE Healthcare) by passive transfer. .. In order to analyze 5S and 5.8S rRNAs, 2 μg total RNAs were separated on 6% polyacrylamide gels (19:1) (Bio-Rad) in Tris/borate/EDTA buffer containing 7 M urea, and then electrotransferred to a nylon membrane overnight. ..

ProLongTM Gold Antifade Mountant with DAPI (#P3693, Thermo Fisher Scientific, Inc., Waltham, MA, USA) was added to the samples and analyzed using Zeiss LSM 880 Confocal Microscope. .. Protein lysates (50 μg) were heated in 1 × LDS loading buffer (Invitrogen) containing 1 mM DTT for 10 min at 70 °C prior to separation on pre-cast 4–12% NuPAGE gel using MES running buffer (50 mM MES (2-[N-morpholino]ethanesulfonic acid), 50 mM Tris base, 1 mM EDTA, 0.1% (w/v) SDS) at 200 V for 1 h. Proteins were then transferred to mini 0.2 μm PVDF membranes (BIO-RAD) using a semi-dry trans-blot Turbo system (BIO-RAD) following the manufacturer’s instructions. .. In Fig. C, Western blotting analysis were performed using rabbit anti-ATP synthase subunit C (ATPsynC) (Abcam, ab181243, 1:1000) and mouse monoclonal actin antibody for data normalization (Sigma, A5441, 1:1000) as primary antibodies.

We found that the C-terminus of IRS-1 undergoes phase separation through mediating self-association. Insulin/IGF signaling leads to tyrosine phosphorylation of IRS-1 which promotes the formation of IRS-1 droplets and the recruitment of downstream effectors to form insulin/IGF signalosomes.
