Nov 4, 2008 · Blue dextran is a soluble dextran derivative consisting of the triazinyl dye Cibacron blue F3GA covalently bound to high molecular weight (2000 kDa) dextran ( Sigma-Aldrich, 1997 ). It was developed for use as a visible marker for void volume in gel filtration chromatography columns ( Dean and Watson, 1979, Subramanian, 1984 ).

The structure of dextran produced depends not only on the family and species of the bacterium but on the strain. They are separated by fractional precipitation from protein-free extracts using ethanol .
To make the microinjection mixture, 1 μL of the RNA mixture prepared in Section 18.2.2 is mixed with 1 μL filter-sterilized blue dextran (30 mg/mL in H 2 O), 0.2 μL RNasin, and H 2 O to 4 μL. Blue dextran is used to mark the injected nuclei. A successful nuclear injection should result in a bluish nucleus.
