Stains

Overcome normal optical limitations in microscopic studies by highlighting specific structures with stains and reagents and then protect samples with fixatives. The fast-acting dyes create strong contrasts between cell components for easier detection or analyses. Sensitive attractions to certain organelle or cellular components differ among offered stains, allowing precise testing modifications. Flexible in use, ready-to-use stains may be handled manually or in conjunction with automatic equipment.

Nucleolus Red™ DCS1 Dead Cell Staining

Supplier: AAT BIOQUEST

Nucleolus Red™ DCS1 is a cell-impermeant fluorescent dye that selectively binds to RNA within the nucleolus, a non-membrane-bound nuclear compartment responsible for ribosomal RNA (rRNA) transcription and processing. Upon binding to RNA, the dye exhibits strong red fluorescence, whereas its interaction with DNA results in only weak fluorescence, providing exceptional specificity for nucleolar RNA detection.

RNA loading dye (2X)

RNA loading dye (2X)

Supplier: Thermo Fisher Scientific

In most denaturing agarose gel systems, bromophenol blue migrates slightly faster than human 5S rRNA, whereas xylene cyanol FF migrates slightly slower than 18S rRNA. RNA loading dye contains the denaturing agent formamide, which allows RNA fragments to separate according to size even during non-denaturing electrophoresis. Formamide also stabilises RNA.

Nucleolus Green™ LCS1 Cell-Permeable

Supplier: AAT BIOQUEST

Nucleolus Green™ LCS1 is a cell-permeant fluorescent dye that selectively binds to RNA within the nucleolus, a non-membrane-bound nuclear compartment responsible for ribosomal RNA (rRNA) transcription and processing. Upon binding to RNA, the dye exhibits strong green fluorescence, whereas its interaction with DNA results in only weak fluorescence, providing exceptional specificity for nucleolar RNA detection.
