Target Validation

Target validation plays a pivotal part during the development of novel therapeutics.

To demonstrate a molecular target is involved in the incidence of disease, and that any modulation would result in a remedial affect, in vitro target validation assessments can be used. Investigation into the toxicity of novel therapeutics on non-target cells and tissues can also be established using in vitro target validation.
