Abstract:
An integrated microsystem, comprising: a microchannel, a field generator to create a magnetic field in at least one first portion of the microchannel having a direction substantially collinear with the direction of flow in the portion of the microchannel, the magnetic field also presenting a gradient, wherein the microsystem additionally comprises a detection area in fluid connection with the microchannel.
Abstract:
The invention relates to a novel enzyme involved in the biosynthesis of mycolic acids and to the use thereof for the screening of antibiotics, especially antimycobacterials. The invention more particularly relates to the Pks13 protein which catalyzes Claisen condensation or malonic condensation in mycolates between an acyl-CoA molecule or an acyl-AMP molecule and an acylmalonyl-CoA molecule to form an intermediate ß-cEto acyl ou ß-cEto ester.
Abstract:
The invention provides an agonist or antagonist of the GPR54 receptor for its use for treating a gonadotropin related disorder; a ligand of the GPR54 receptor for its use for diagnosing a subject's gonadotropin abnormality; a method for screening a compound that affect the gonadotropic axis comprising the step of assaying the compound in the presence of a GPR54 receptor and novel proteins useful in the above.
Abstract:
