Purpose of the Study:
- To develop a high-sensitivity western blot protocol for analyzing proteins in low numbers of HSCs.
- To improve HSC isolation and detection sensitivity for scientific studies.
Main Methods:
- Protocol details murine bone marrow cell isolation and antibody staining.
- Utilizes fluorescence-activated cell sorting (FACS) for HSC purification.
- Describes a western blot procedure optimized for limited cell quantities.
Main Results:
- The protocol enables high-sensitivity western blot analysis on HSCs.
- Enhanced HSC isolation and detection sensitivity were achieved.
- Successfully adapted western blot for low cell number analysis.
