Method of obtaining and/or verifying a binder to prepro-Vasopressin (SEQ ID NO. 1) or fragments thereof of at least 6 amino acids in length, including Copeptin (SEQ ID NO. 2), comprising at least one of the steps of: a) generating the binder using a developer comprising an amino acid sequence of at least 6 amino acids in length contained in an amino acid sequence corresponding to the C-terminal part but lacking amino acid 164 of prepro-Vasopressin (SEQ ID NO. 1); b) determining whether the binder is capable of binding to an amino acid sequence of at least 4 amino acids in length contained in an amino acid sequence corresponding to the C-terminal part but lacking amino acid 164 of prepro-Vasopressin (SEQ ID NO. 1); c) selecting and optionally isolating the binder from a plurality of binders which is capable of binding to an amino acid sequence contained in an amino acid sequence corresponding to the C-terminal part but lacking amino acid 164 of prepro-Vasopressin (SEQ ID NO. 1); d) carrying out binding assays with the binder in order to determine the ex vivo stability of prepro-Vasopressin or fragments thereof of at least 6 amino acids in length, including Copeptin, in a biological sample; e) carrying out binding assays with the binder and another binder for comparison purposes in order to determine the concentration of prepro-Vasopressin or fragments thereof of at least 6 amino acids in length, including Copeptin, in a biological sample; wherein the C-terminal part consists of amino acids 138 to 164 of prepro-Vasopressin (SEQ ID NO. 1), in order to obtain a binder or a mixture of binders capable of binding to an epitope contained in an amino acid sequence corresponding to amino acids 138 to 163 but lacking amino acid 164 of prepro-Vasopressin (SEQ ID NO. 1).

A method for refining vasopressin, including: subjecting a crude vasopressin solution to reversed-phase enrichment, reversed-phase salt conversion and reversed-phase purification sequentially using reversed-phase high performance liquid chromatography. The crude vasopressin solution is obtained by oxidizing a crude reduced vasopressin prepared by solid phase synthesis. A super water-resistant packing material is used in the reversed-phase high performance liquid chromatography.

Methods and compositions are provided for treating and preventing preterm labor using liposome encapsulated tocolytic agents, such as indomethacin. In certain aspects, targeted liposomes are provided that allow delivery of tocolytic agents directly to the uterus, such as by targeting to the oxytocin receptor.
