Cell Type-specific mRNA Purification in Caenorhabditis elegans via Translating Ribosome Affinity Purification

Development of translating ribosome affinity purification for zebrafish.

The regulation of transcription and translation by specific cell types is essential to generate the cellular diversity that typifies complex multicellular organisms. Tagging and purification of ribosomal proteins has been shown to be an innovative and effective means of characterizing the ribosome bound transcriptome of highly specific cell populations in vivo. To test the feasibility of using ...

TRAP-rc, Translating Ribosome Affinity Purification from Rare Cell Populations of Drosophila Embryos.

Measuring levels of mRNAs in the process of translation in individual cells provides information on the proteins involved in cellular functions at a given point in time. The protocol dubbed Translating Ribosome Affinity Purification (TRAP) is able to capture this mRNA translation process in a cell-type-specific manner. Based on the affinity purification of polysomes carrying a tagged ribosomal ...

Affinity purification of protein complexes in C. elegans.

C. elegans is a powerful metazoan model system to address fundamental questions in cell and developmental biology. Research in C. elegans has traditionally focused on genetic, physiological, and cell biological approaches. However, C. elegans is also a facile system for biochemistry: worms are easy to grow in large quantities, the functionality of tagged fusion proteins can be assessed using mu...

Affinity purification

Stereomicroscope The new Carl Zeiss stereomicroscope Stemi 2000-CS allows the user to view the sample whilst other observers view the procedure by video. Greenough type stereomicroscopes create their stereo effect by having separate light paths set at different angles, one for each eye. However, when video or photomicrography is being carried out most stereomicroscope systems remove light from ...
