Cells were lysed and sonicated in radioimmunoprecipitation (RIPA) buffer with protease inhibitor mixture, PMSF, and sodium orthovanadate. Protein concentration was measured by BCA protein assay (Thermo scientific, Rockford, IL, USA). The samples were resolved by SDS-PAGE and transferred to nitrocellulose membrane and blotted with specific antibodies: anti-p58IPK, anti-p-NF-κB, anti-NF-κB, anti-p-p38, anti-p38, anti-p-JNK, anti-JNK, (Cell Signaling Technology, Boston, MA, USA), anti-p-PKR, anti-PKR, anti-β-actin (Santa Cruz Biotechnology, Santa Cruz, CA, USA), anti-IL-1β (R&D Systems, Inc., Minneapolis, MN, USA), anti-caspase-1 (p-20), and anti-NLRP3 (AdipoGen, Inc, San Diego, CA, USA). The immunoblots were developed using chemiluminescence (SuperSignal West Dura Extended Duration Substrate, Thermo Scientific, USA) and visualized under Chemidoc MP Imaging System (Bio-Rad, Hercules, CA, USA).

Mouse retinal tissue or BMDMs were lysed with radio immune precipitation assay (RIPA) buffer with a protease inhibitor mixture, PMSF, and sodium orthovanadate (Santa Cruz Biotechnology). Protein concentration was quantified using the PierceTM BCA protein assay kit (ThermoFisher). Samples were loaded into a 10% SDS-PAGE gel, and transferred to nitrocellulose membrane for immunoblotting using anti-p58IPK (Cell Signaling Technology, Danvers, MA, USA, C56E7, 1:1000) and anti-β-actin (Abcam, Cambridge, United Kingdom, ab8226, 1:10000) antibody. After incubation with HRP-conjugated secondary antibodies, membranes were developed with Clarity and Clarity Max ECL Western Blotting Substrate (Bio-Rad, CA, USA) using Chemi-Doc MP Imaging System (Bio-Rad, CA, USA). The bands were semi-quantified by densitometry using Image J software.

Quantitative analysis of UPR markers

Check if the same lab product or an alternative is used in the 5 most similar protocols
Cells were lysed in M-PER mammalian protein extraction reagent containing Halt Protease (Pierce Biotechnology, Rockford, lL) following the manufacturer’s recommendations. Twenty micrograms of proteins from these cell free extracts were analyzed on SDS-PAGE (Bio-Rad, Hercules, CA) and transferred to nitrocellulose membrane using Trans-Blot Turbo transfer system (Bio-Rad, Hercules, CA). Membranes were probed with rabbit anti-BiP, anti-PDI, anti-p-PERK, anti-eIF2α, anti-P-eIF2α, anti-P58IPK (Cell Signaling, Boston, MA, USA), mouse anti-ATF-6 (Pierce Biotechnology; Rockford, lL, USA), and rabbit anti-XBP1 (Abcam, Cambridge, MA, USA). Antigen specific bands were detected by incubation of membranes using HRP-conjugated anti-rabbit or anti-mouse antibodies followed by incubation with SuperSignal West Pico Chemiluminescent Substrate (Pierce Biotechnology, Rockford, lL, USA) and image analysis by ImageQuant LAS4000 (GE Heathcare Bio-Sciences, Pittsburgh, PA, USA).

Western Blot Analysis of Stress Markers

Check if the same lab product or an alternative is used in the 5 most similar protocols
Radioimmuno precipitation assay (RIPA) buffer with protease inhibitor mixture, PMSF, and sodium orthovanadate (Santa Cruz Biotechnology, Santa Cruz, CA, USA) was used to extract the proteins from cells or tissues. A BCA protein assay kit (Thermo Fisher Scientific, Inc., Rockford, IL, USA) was used to measure protein concentration. Twenty-five micrograms of protein were resolved by SDS-PAGE and blotted with specific antibodies: anti-XBP1, anti-ATF4 (CREB2; Santa Cruz Biotechnology); anti-cleaved caspase-3, anti-ZO-1, anti-occludin (Invitrogen, Carlsbad, CA, USA), anti-p-eIF2α, anti-CHOP, anti-p58IPK (Cell Signaling Technology, Boston, MA, USA); or anti-KDEL, anti-ATF6 (Abcam, Cambridge, MA, USA). The same membrane was stripped and reblotted with an anti-β-actin antibody (Abcam) as loading control. After incubation with peroxidase-labeled secondary antibodies (Vector Laboratories, Inc., Burlingame, CA, USA), membranes were developed with SuperSignal West Dura Chemiluminescent Substrate (Thermo Fisher Scientific, Inc., Rockford, IL, USA). Protein bands were quantified by densitometry, normalized to β-actin (loading control).

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.
