What is the main advantage of this protocol?
The protocol is fast, reliable, and allows for the isolation of specific cell types from a heterogeneous mixture.
What type of mouse is used in this study?
The protocol uses 50 to 80 day old mice in the telogen phase of the hair follicle cycle.
What is FACS analysis?
FACS (Fluorescence-Activated Cell Sorting) is a technique used to sort and analyze cell populations based on their specific characteristics.
How is the skin prepared before isolation?
The skin is shaved and disinfected with 70% ethanol to remove hair residue and prevent contamination.
Who demonstrates the procedure?
Dr. Yahav Yosefzon from the laboratory demonstrates the procedure.
