Neuro2a Cells JEV Infection Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
For flow cytometry analyses, Neuro2a cells were seeded in 2 × 106cells/well density in 6-well plate and incubated for 12 h at 37°C, 5% CO2 incubator. JEV infection were given in three wells at 0.1MOI. The 1b and 1f treatment was given at 15μM concentration separately in JEV infected and non-infected cells 2 h post-infection. Untreated and uninfected controls were kept along with one DMSO (0.1%) control. After 48 h of incubation, cells were pelleted and washed with 1% phosphate buffer saline (PBS, pH 7.4). Further, cells were suspended in 500μl of 1% PBS and incubated with 10μM 2′,7′-dichlorodihydrofluorescin diacetate (H2DCF-DA) for 30 min at 37°C. The stained cells were analyzed using flow cytometry (BC, CytoFlex S Analyser). The DJ-1(5933, CST, USA), SQSTM1 (39749, CST, USA), HO-1 (43966, CST, USA), NQO1 (62262, CST, USA), antibodies were used to explore the modulation of NRF2-SQSTM1 pathway in the cells. The β-actin was used as a loading control for all the experiments (MA1-91399, Invitrogen).

TLR3-Induced Signaling Pathway Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
Cells were cultured at a density of 100 × 104 cells in a 60-mm culture plate (Tarsons-960020). Four hours before the addition of the TLR3 ligand, the MyD88 inhibitor was added and incubated for 24 h. Cells were lysed using RIPA buffer, and gel electrophoresis was performed using acrylamide gel. Proteins were transferred to PVDF membranes and blotted with antibodies against interleukin 1 receptor-associated kinase 1 (IRAK1; Invitrogen-38-5600), phospho IRAK1–Thr209, (Invitrogen-PA5-38633), transforming growth factor beta-activated kinase 1 (TAK1; Invitrogen-700 113), phospho TAK1–Thr184/187 (Invitrogen-MA5-15073), TGF-beta-activated kinase 1 (TAB1; Invitrogen-PA5-28683), TNF receptor-associated factor 6 (TRAF6; Invitrogen-PA5-29622), and cyclin D1 (Invitrogen-AHF0082). The antibody against β-actin (Invitrogen-MA191399) was used as a loading control.

Cells were cultured at a density of 100x10 4 cells in 60 mm culture plate (Tarsons-960020). Four hours before the addition of TLR3 ligand, MyD88 inhibitor was added and incubated for 24 hours. Cells were lysed using RIPA buffer and gel electrophoresis was performed using acrylamide gel. Proteins were transferred to PVDF Membranes and blotted with antibodies against IRAK1 (Invitrogen-38-5600), phospho IRAK1-Thr209, (Invitrogen-PA5-38633), TAK1 (Invitrogen-700 113 ), phospho TAK1-Thr184/187 (Invitrogen-MA5-15073), TAB1
(Invitrogen-PA5-28683), TRAF-6 (Invitrogen-PA5-29622), and Cyclin D1 (Invitrogen-AHF0082). The antibody against β-actin (Invitrogen-MA191399) was used as a loading control.

Western Blot Analysis of PIP5K1γ Expression

Check if the same lab product or an alternative is used in the 5 most similar protocols
Protein from cultured fibroblasts was harvested and lysates were blotted as previously described.111 (link) anti-PIP5K1γ (ABS190; 1:300; Sigma) and anti-β-actin (MA1-91399; 1:1000; Thermo-Fisher) were applied to transferred membranes overnight at 4°C. Blot bands were detected by Sapphire Biomolecular Imager (Azure Biosystems) after 1 h incubation in the following secondary antibodies: goat anti-rabbit 680RD (P/N 926–68071, 1:10,000; LI-COR), goat anti-Mouse 800CW (P/N 925–32210, 1:10,000; LI-COR). Images were processed on ImageJ using the BioImporter plugin tool to calculate the protein expression for each band. Protein abundance was first normalized to beta-actin intensity then normalized to control cell intensity.

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.
