Methods for conducting metabolic analyses

   
   

The present invention provides methods and apparatus for purifying metabolites of interest and conducting metabolic analyses. The methods generally involve determining metabolic flux values for a plurality of target analytes by monitoring the relative isotope abundance of a stable isotope in a substrate labeled with the stable isotope and/or one or more target metabolites formed through metabolism of the labeled substrate. Certain methods utilize multiple electrophoretic methods to separate the target analytes from other components within the sample being analyzed. The methods can be used in a variety of applications including screens to identify metabolites that are correlated with certain diseases and diagnostic screens for identifying individuals having, or susceptible to, a disease.

A invenção atual fornece métodos e instrumento para metabolites purifying do interesse e de análises metabolic conduzindo. Os métodos envolvem geralmente determinar valores metabolic do fluxo para um plurality de analytes do alvo monitorando a abundância relativa do isotope de um isotope estável em uma carcaça etiquetada com o isotope e/ou o um ou mais estável metabolites do alvo dados forma através do metabolism da carcaça etiquetada. Determinados métodos utilizam métodos electrophoretic múltiplos para separar os analytes do alvo de outros componentes dentro da amostra que está sendo analisada. Os métodos podem ser usados em uma variedade das aplicações including telas identificar os metabolites que são correlacionados com determinadas doenças e as telas diagnósticas para identificar os indivíduos que têm, ou suscetível a, uma doença.
