Molecular characterization of diphtheria toxin
repressor (dtxR) genes present in nontoxigenic Corynebacterium diphtheriae strains isolated in the United Kingdom.
One molecule of diphtheria toxin
fragment A introduced into a cell can kill the cell.
The agent specifically binds to IL-2 receptors on the cell surface, causing diphtheria toxins
that have entered cells to inhibit protein synthesis.
Neo gene was used as a positive selection marker and diphtheria toxin
A was used as a negative selection marker.
Topology of diphtheria toxin
B fragment inserted in lipid vesicles.
Micro cell culture method for determination of diphtheria toxin
and antitoxin titres using VERO cells.
The CD4+ T cells in the researchers' mice were engineered to express a toxin, diphtheria toxin
A fragment, upon activation.
This method was found useful to detect the diphtheria toxin
in the 1990s epidemic in Russia and the Ukraine.
diphtheriae is diphtheria toxin
(DT)  a highly toxic protein expressed after infection by a specific tox+ corynebacteriophage (1).
While these studies may differ with regard to which protein the Hib is conjugated to (tetanus toxoid protein (PRP-T) or mutant diphtheria toxin
CRM197 (HbOC)), there is growing evidence that reduced amount of antigen in the vaccine, e.
And in contrast to Prevnar, in which the seven strains are conjugated to a nontoxic mutant of diphtheria toxin
(CRM 197), the 11 pneumococcal serotypes of this investigational vaccine--hereafter called the protein D conjugate vaccine--are conjugated to a carrier protein derived from H.
When the animals were treated with diphtheria toxin
, which preferentially kills human rather than mouse cells, the tumours began to die off.
The cancer cells that had the growth factor were almost completely ablated by the diphtheria toxin
,'' he said.
This is combined with part of the luteinizing hormone found in sheep and either the tetanus or diphtheria toxin
, which boost the body's immune response.
BC-819 uses the H19 gene to synthesize Diphtheria Toxin
in cancerous cells only, in order to destroy the cells.
