The largest database of trusted experimental protocols

Ne per cytoplasmic and nuclear extraction reagents

Manufactured by Thermo Fisher Scientific
Sourced in United States

The NE-PER cytoplasmic and nuclear extraction reagents are a set of solutions designed to separate cellular components, specifically the cytoplasm and nuclei, for further analysis. The reagents facilitate the extraction and isolation of these cellular fractions, enabling researchers to study their respective contents and functions.

Total RNA was extracted using TRIzol reagent (Invitrogen, Carlsbad, CA, USA). The cytoplasmic and nuclear fractions were extracted using NE-PER Cytoplasmic and Nuclear Extraction Reagents (Thermo Scientific). The miRNA was reversed transcribed using M-MLV Reverse Transcriptase (Promega, Madison, WI, USA) and cDNA was synthesized by PrimeScript RT reagent kit (Promega, Madison, WI, USA). The qRT-PCR was performed using SYBER Green PCR Master mix (Takara Bio, Inc.,Shiga, Japan). All the primer sequences are listed in Supplementary Table 1. Gene expression level was calculated with 2-ΔΔCt method.

Total protein extracts from cell lines were obtained as previously described (15 (link)). Cytoplasmic and nuclear extracts was processed using NE-PER cytoplasmic and nuclear extraction reagents (Thermo Scientific) according to manufacturer’s instructions. Conditioned medium was collected by maintaining the cells in serum free medium. Samples were resolved using SDS-PAGE, transferred to nitrocellulose membrane (Bio-Rad) and probed with sheep anti-CITED2 (1:250; R&D Systems), rabbit anti-IKKα, anti-IκBα, anti-p65, anti-RelB, anti-HDAC1 (1:1000; Cell Signaling Technology), mouse anti-GAPDH (1:10,000; kindly provided by Dr. Shanmugasundaram Ganapathy Kanniappan, Johns Hopkins University School of Medicine, Baltimore, MD) or Actin (1:1000; Sigma-Aldrich) antibodies. Membranes were incubated with horseradish peroxidase-conjugated antibody against sheep (1:2000; R&D Systems), rabbit or mouse (1:2000; GE HealthCare) IgG and binding was revealed by chemiluminescence detection (Millipore).

This study utilized the NE-PER Cytoplasmic and Nuclear Extraction Reagents (Thermo Fisher Scientific) to separate the cytoplasmic fraction from the nuclear counterpart in line with specific protocols. Thereafter, total RNA was extracted by adopting the RNA Isolation Kit (Tiangen Biotech, Beijing, China). Afterward, the cytoplasmic-to-nuclear ratio of specific RNA expression was measured through qRT-PCR, with GAPDH being the cytoplasmic reference and U6 being the nuclear reference.

LPS-Stimulated RAW 264.7 Cell Fractionation

Check if the same lab product or an alternative is used in the 5 most similar protocols
RAW 264.7 cells were seeded at 1 × 106 cells/mL on six-well plates and were treated with RRE and stimulated with LPS for indicated periods. After incubation, cells were harvested by centrifugation and washed twice with ice-cold PBS. To obtain whole cell lysates, pellets were resuspended in radioimmunoprecipitation assay (RIPA) lysis buffer (Millipore, Bedford, MA, USA) containing protease and phosphatase inhibitors. Cell debris was removed after centrifugation. The cytosolic and nuclear proteins were extracted using NE-PER cytoplasmic and nuclear extraction reagents according to the manufacturer's instructions (Thermo Scientific, Rockford, IL, USA).

Transfected cells were treated with TPA or TNF-α for 3 h, washed with PBS, and pelleted by centrifugation. Nuclear and cytoplasmic extracts were prepared using NE-PER cytoplasmic and nuclear extraction reagents (Thermo Fisher Scientific). Nuclear and cytoplasmic protein fractions were obtained according to the manufacturer’s instructions (Thermo Fisher Scientific).

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.
