简介：

Overview

This method involves culturing human primary muscle cells in vitro to obtain differentiated myotubes and measure glucose uptake rates. The protocol quantifies glucose uptake in both basal and insulin-stimulated states using radiolabeled [3H] 2-deoxy-D-Glucose.

Key Study Components

Area of Science
