Abstract: Provided herein is a method for synthesizing polynucleic acids, comprising the steps of (a) providing an acidic solution substantially free of nucleic acid polymerase and lipids, but containing mononucleotides and a monovalent salt; (b) drying and resolubilizing the mixture of step (a) a plurality of times; and (c) recovering polynucleic acids from a resolubilized mixture of step (b). In certain aspects, the method further uses a low pH, e.g. about 3; it can utilize monophosphates, such as AMP rather than ATP; and it can be used with a polynucleotide template to form a sequence at least partially complementary to said template. Thus, both single-stranded and double-stranded polynucleic acids are provided. Ammonia salts have been used to obtain RNA lengths from 10 to 300 nucleotides after 16 half hour cycles and an effective temperature includes between 80° C. and 100° C.

Abstract: The invention relates to antibodies directed against follicle-stimulating hormone (FSH) and capable of potentiating the bioactivity of gonadotropins.

Abstract: The invention relates to a ligand of a luteinizing hormone (LH), characterized in that it comprises the paratope of an ovine anti-LH antibody of which the variable domain of the heavy chain contains the following CDRs: —VH-CDR1, defined by the sequence GYTFTNYW (SEQ ID NO: 13); —VH-CDR2, defined by the sequence IYPGGGYT (SEQ ID NO: 14); —VH-CDR3, defined by the sequence ARTPLYGSSYGGFAY (SEQ ID NO: 15); and the variable domain of the light chain contains the following CDRs: —VL-CDR1, defined by the sequence QGISNY (SEQ ID NO: 16); —VL-CDR2, defined by the sequence YTS; —VL-CDR3, defined by the sequence QQYSKLPWT (SEQ ID NO: 17). The invention also relates to a ligand-gonadotrophin (LH, hCG, FSH) complex. The ligand or the complex according to the invention can be used to induce ovulation in a female mammal.

Abstract: An assay for detecting the presence and amount of a hormone in culture media or a biological sample includes the steps of preincubating two antibodies specific for the hormone to be assayed in a preincubation medium that is essentially free of the hormone to be detected, contacting a sample to be tested with the preincubated antibodies, and detecting hormone-antibody complexes formed in the contacting step. This assay reduces or eliminates non-specific interference and thereby increases the sensitivity of the assay.
