Quantitative microscopic approaches for studying kidney functions

Abstract

Intravital ratiometric microscopy is a powerful method for quantitative study of kidney functions. As demonstrated in the examples, both the generalized polarity and direct ratio imaging approaches allow investigators to address basic and important questions such as those related to filtration, permeability and reabsorption. Both approaches have similar advantageous for in vivo imaging. However, they have different sensitivities and responses to the component intensity changes. Therefore, investigators must design their experiments based on the characteristics of the generalized polarity function and direct ratio approach. Copyright © 2006 S. Karger AG.
