Protocols describe methods for analyzing tissue microenvironments using advanced proteomic techniques.
To decipher the complex tissue microenvironment for comprehensively elucidating the biological machinery, spatial proteomics is becoming popular. Laser microdissection (LMD) technology combined with integrated sample preparation and high-sensitive liquid chromatography-mass spectrometry (LC-MS) is the most powerful strategy. In this chapter, we describe the protocols for tissue slice preparation and staining, LMD-based histological regions collection, simple and integrated spintip-based proteomics technology (SISPROT) based sample preparation, and highly sensitive LC-MS analysis.
