Gfp fixation fluorescence

WebOct 12, 2012 · One of the problems with GFP is that it may lose its fluorescence during tissue fixation or subsequent processing (Swenson et al., 2007). Therefore, immunostaining with commercial antibodies is often used for detecting GFP. GFP expression can vary considerably, even among similar cell types in a single animal. WebGFP is a fluorescent protein that can be expressed in vivo. If GFP is exposed to light, it emits a green fluorescent signal. This property has had an enormous impact on cell biology by enabling the imaging of almost any protein, in transcription studies by working as a reporter gene, and in biochemical applications. 2.
