cleavages Protocols

Category: C. elegans Protocols

To image early cleavages and chromatin dynamics, it is convenient to use histone H2B fused to GFP or lamin::GFP. Time-lapse movies can be obtained using conventional confocal microscope systems and their included software. Early embryos dissected from transgenic hermaphrodites are placed with egg salts on agar pads. - [Read Live Imaging of Caenorhabditis elegans: Examples]

To image early cleavages and chromatin dynamics, it is convenient to use histone H2B fused to GFP or lamin::GFP. Time-lapse movies can be obtained using conventional confocal microscope systems and their included software. Early embryos dissected from transgenic hermaphrodites are placed with egg salts on agar pads. Chromatin dynamics can be followed easily, and wild-type embryonic cells can be compared with mutants or RNAi-treated embryos. - [Read Protocol Live Imaging of Caenorhabditis Elegans]

Searches are not constrained for only tryptic peptides, and indexed databases (databases only containing tryptic peptides) are not used. In cases where there are very complex mixtures, such as cell lysates, nonspecific cleavages can occur. Therefore, nontryptic peptides would be missed in the database search. - [Read The Use of Mass Spectrometry in Proteomics: Database Searching]
