The cells were lysed on ice using RIPA buffer for 30 minutes by intermittent vortexing and incubation on ice during this period. Protein concentration of whole cell lysates was measured using the Bradford assay (Bio‐Rad). Whole cell lysates (20 μg) for each sample was separated on 8% sodium dodecyl sulfate polyacrylamide gel electrophoresis gel. The separated proteins were transferred onto a polyvinylidene difluoride membrane followed by blocking at room temperature using 5% non‐fat milk diluted in 0.1% TRIS‐buffered saline‐Tween‐20 for an hour. This was followed by an overnight incubation with either anti‐TonEBP (Abcam), anti‐VDR (Santa Cruz), anti‐total p38 (Cell Signaling Technology, Danvers, MA), anti‐phosphorylated p38 (Cell Signaling Technology), anti‐CFTR (Abcam), anti‐tubulin (Cell Signaling Technology), or anti‐beta actin (Santa Cruz) primary antibodies at 4°C. The membranes were washed and incubated with the relevant secondary antibodies conjugated with HRP (anti‐mouse and anti‐rabbit; BosterBio, Pleasanton, CA) for an hour at room temperature. The membranes were washed and incubated with Clarity ECL Western blotting substrate (Bio‐Rad) and resulting chemiluminescence was imaged using Image quant (GE Image Quant LAS 500; GE Healthcare, Chicago, IL). Densitometry analysis was done using ImageJ software (version 6, NIH, Bethesda, MD).

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.
