The extraction of total protein was finished through the usage of RIPA (CWBio, Beijing, China) and the concentrations of proteins were determined through the usage of BCA Protein Quantification Kit (Vazyme). Next, the proteins were loaded on SDS-PAGE gel (Solarbio) and blotted onto PVDF membranes (Amersham Biosciences, Chicago, IL, USA). After blocking in 5% defatted milk for 1 h, the membranes were cultivated overnight with primary antibodies at 4°C followed by incubation with secondary antibody (ab205719; Abcam, Cambridge, MA, USA) for 1 h at indoor temperature. The blots were examined with an ECL detection kit (Pierce Biotechnology, Rockford, IL, USA). The primary antibodies were: Bcl-2 (ab182858; Abcam), Bax (ab32503; Abcam), cleaved-caspase-3 (c-caspase-3; ab49822; Abcam), PRKACB (ab26322; Abcam) and GAPDH (ab9485; Abcam).

Mouse monoclonal antibodies used were anti-GFP ([1:100] Sigma-Aldrich, G6539), acetylated tubulin ([1:1,000] Sigma-Aldrich, T7451) and anti-histone H2B ([1:50] Abcam, ab52484) antibodies. Rabbit polyclonal antibodies used were anti-γ-tubulin ([1:1,000] Sigma-Aldrich, T5192), anti-lamin A/C ([1:20] Santa Cruz Biotechnology, H110), anti-cAMP protein kinase catalytic subunit ([1:1,000] Abcam, ab26322) and anti-CBX/HP1 beta antibodies ([1:100] Abcam, ab10478). TRITC or Alexa Fluor 647 conjugated secondary antibodies (Jackson Immuno Research Laboratories, Inc. or Life Technologies, respectively) were used for indirect immunofluorescence detection. BG-conjugated dyes, including SNAP-Surface Alexa Fluor 647 and 546 (NEB), were used for staining SNAP-tag expressed in cells.
The cells were fixed with 4% formaldehyde (Electron Microscopy Sciences) for 15 min, permeabilized with 0.1% Triton X-100 in phosphate-buffered saline (PBS), stained for primary antibodies and Alexa-Fluor-conjugated secondary antibodies, or BG-conjugated fluorophores for SNAP-tag at 4 °C overnight.

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.
