Biosyntheticlabeling
How long should cells be labeled? The ideal length of time to label cells depends on the protein of interest and the label that you are using. If you want to label an unstable protein with 35S-methionine, a short labeling interval--no more than 2 hr--is best. If you are studying a stable protein, a longer label may be preferable. The issue is the half-life of the protein of interest relative to the half-life of ......阅读全文
