The directive should take a clear stand and insist that the use of these marker genes is stopped now.

F9 cell differentiation is characterised by the induction of different marker genes.

Two others have just the marker gene, Dr. Campbell said.

USC1.0 also contains the mini- white +transformation marker gene.

We have achieved the phasing out of all harmful, antibiotic-resistant marker genes.

Typical marker genes are for antibiotic resistance or nutrient biosynthesis.

The marker genes tell the researchers "which lymphcytes are actually working to stop the cancer," allowing them to more accurately target their effort.

The disputed antibiotic-resistant marker genes will be banned in Europe in the future.

We wanted all concerns regarding the possible presence of an antibiotic resistance marker gene to be thoroughly assessed.

An advisory committee to the agency recommended approval of the marker gene technique for smallpox last November.

An E. coli selectable marker gene, often some kind of antibiotic resistance.

In the first trial the cells will be given a marker gene to allow them to be traced in the body.

So, for example, the "marker gene" could be for resistance to the antibiotic ampicillin.

The gene, known as a marker gene, is used by the manufacturer to identify a successful splicing.

DNA Plant announced today that it had developed a marker gene derived from plants.

Two other lambs were born a couple of days ago and are expected to have the human gene and the marker gene.

The hybrid virus was then sprayed into the respiratory systems of mice, where it successfully delivered the marker gene.

These animals were transfected but contained a marker gene not the cloned gene of interest.

Most of the currently identified marker genes are not appropriate for the analysis of the phenotype of these lines.

There is another aspect which affects the substance of the matter we are discussing, and that is the question of marker genes.

If a cell has been successfully transformed with the DNA it will also contain the marker gene.

Select plasmids for the E. coli selectable marker gene.

Offspring of the strain thus contain not only the genes for which they were bred and patented, but also the luciferase marker gene.

Successful transplantation of the marker genes would also help scientists gauge how well human genes function after they are transplanted.

The DNA used in these preliminary experiments carried a marker gene, which was expressed, but no known human genes.
