Suggested reading for new users:

Each of the papers listed below is recommended reading for new users of colored and fluorescent microspheres:

*  The information presented in Buckberg, et al is important in determining the number of microspheres that will need to be injected in order to insure valid results for each tissue or blood sample..

*  Millard, et al warns that some animals may have a transient cardiovascular response to the Tween 80 surfactant that is used to bottle most microsphere types.  Millard, et al also presents a remedy to this effect.

The remaining papers are validation papers for the colored and fluorescent microsphere types for measuring regional blood flow in animal models.
