What is the main advantage of this technique?
The technique is fast and allows simultaneous observation of nuclear staining and sub-cellular localization changes.
How are the extrachromosomal arrays generated?
They can be generated with translational constructs of target genes or obtained from public resources like the Caenorhabditis Genetic Center.
What role does gamma radiation play in this protocol?
Gamma radiation is used to integrate the extrachromosomal lines into the genome of C.elegans.
What markers are used in this study?
Marker proteins such as GFP or roller are used to visualize protein expression.
Can this method be applied to other organisms?
While this protocol is demonstrated in C.elegans, similar methods may be adapted for other model organisms.
