Mouse Adipose Tissue Collection and Processing for RNA Analysis.

Area of Science:

• Molecular Biology
• Biochemistry
• Genetics

Background:

• White adipose tissue (WAT) has low RNA and protein content due to high lipid concentration, complicating molecular analyses.
• Standard RNA isolation from WAT requires additional steps to remove lipids, posing a challenge for techniques like real-time PCR and Western Blot.

Purpose of the Study:

• To present a detailed protocol for collecting and processing anatomically distinct mouse white adipose tissues.
• To describe RNA isolation, cDNA synthesis, and gene expression analysis using real-time PCR from WAT samples.
• To optimize the protocol for reduced contamination and improved RNA yield and quality.

Main Methods:

• Collection of three distinct white adipose tissue types from mice.
• Processing of tissue samples to minimize hair and blood contamination.
• RNA isolation, cDNA synthesis, and quantitative real-time PCR (qRT-PCR) for gene expression analysis.

Main Results:

• The protocol effectively reduces contamination from hair and blood.
• It minimizes cross-contamination between different fat pads during collection.
• Optimized RNA extraction yields adequate quantity and quality for downstream applications.

Conclusions:

• This protocol provides a reliable method for RNA isolation from mouse white adipose tissue.
• It is suitable for routine gene expression studies using real-time PCR across various mouse models.
• The method is not intended for primary adipocyte cell cultures.
