Green fluorescent protein as an indicator of cryoinjury in tissues. [PDF]

open access: yes, 2013
The fluorescence intensity of Green Fluorescent Protein (GFP) has previously been demonstrated to be an accurate indicator of cellular viability following cryoinsult in individual GFP-transfected cells. In an attempt to ascertain whether GFP fluorescence
