# Protocol for mitochondria lipid encapsulation using a dual-tube system for mitochondria transfer therapy

## TL;DR

This paper introduces a protocol for modifying mitochondria with a lipid coat to improve ATP restoration in cells under oxidative stress, potentially aiding CNS disorders.

## Contribution

A novel dual-tube system for lipid encapsulation of mitochondria to enhance their therapeutic potential in neuroprotection.

## Key findings

- A protocol is described for isolating mitochondria and encapsulating them with a lipid coat using a dual-tube system.
- The method aims to enhance intracellular ATP production under oxidative stress conditions.
- Detailed procedures are provided for handling lipid-coated mitochondria and performing relevant assays.

## Abstract

Mitochondria transplantation therapy is emerging as a novel therapeutic approach to promote neuroprotection in central nervous system (CNS) disorders. Here, we present a protocol for mitochondrial surface modification that enhances the restoration of intracellular adenosine triphosphate (ATP) levels under conditions of oxidative stress. We describe steps for isolating mitochondria, preparing the dual-tube system, and encapsulation with lipid coat. We then detail procedures for performing assays and analyses.
