Cells were lysed in RIPA buffer supplemented with a protease inhibitor cocktail (Calbiochem) as described [17 (link)]. Equal amounts of protein were separated by SDS-PAGE, transferred to Immobilon-FL polyvinylidene fluoride (PVDF) transfer membrane (Millipore), and immunostained. Immunoblots were visualized using an Odyssey infrared scanner (LI-COR).

Western Blot Analysis of iPLA2 Expression

Check if the same lab product or an alternative is used in the 5 most similar protocols
Cells were grown to confluence in a 15-cm dish, washed twice with phosphate buffered saline (PBS), and cell lysate was collected in 600 μL radioimmunoprecipitation assay (RIPA) buffer (Sigma-Aldrich, St Louis, Missouri, USA) containing Protease inhibitor cocktail (Roche, Manheim, Germany). Samples were sonicated for 10 min in an ultrasonic bath. 25μg of total protein, as determined by the DC Protein assay (BioRad, Hercules, Virginia, USA), was loaded on a 4% stacking—10% resolving polyacrylamide gel. Proteins were transferred to a 0.45-μm Immobilon-FL polyvinylidene fluoride (PVDF) transfer membrane (Millipore, Billerica, Massachusetts, USA) and probed with anti-iPLA2 (C-terminal region) produced in rabbit (SAB4200130, Sigma-Aldrich, St Louis, Missouri, USA) and monoclonal anti-GAPDH antibody produced in mouse (G8795, Sigma-Aldrich, St Louis, Missouri, USA). Li-cor Donkey antirabbit IRDye 680RD (Li-cor, Lincoln, Nebraska, USA) and Li-cor Donkey anti-mouse IRDye 800CW (Li-cor, Lincoln, Nebraska, USA) were used as secondary antibodies and fluorescence was measured on a 9140 Odyssey CLx infrared imaging system (Li-cor, Lincoln, Nebraska, USA). Bands were analysed using Image Studio software (Li-cor, Lincoln, Nebraska, USA).

Cells were lysed in RIPA buffer supplemented with a protease inhibitor cocktail (Calbiochem) as described [58 (link)]. Equal amounts of protein were separated by SDS-PAGE, transferred to Immobilon-FL polyvinylidene fluoride (PVDF) transfer membrane (Millipore), and immunostained. Immunoblots were visualized using an Odyssey infrared scanner (LI-COR). Immunoprecipitations were performed as described [59 (link)].

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.
