Abstract:
In a competitive receptor binding assay for detecting TSH-receptor auto-antibodies in a biological sample, the sample is reacted in a reaction mixture which contains (i) a TSH-receptor or TSH-receptor preparation; (ii) a primary competitor, for example labelled TSH; and (iii) an agent for separating a complex composed of the TSH-receptor and the elements bound thereto of the reaction mixture from the liquid phase. According to the invention, the reaction is carried out in the presence of at least one monoclonal or polyclonal antibody specific against a partial peptide sequence of the TSH eceptor. This specific antibody is used to immobilize a complex of TSH-receptor and primary competitor and/or as secondary competitor for another part of the TSH-receptor auto-antibodies expected in a sample. The primary or secondary competitors are or can be selectively labelled.
Abstract:
Specific epitopic regions of thyroid peroxidase (TPO), a thyroid specific membrane autoantigen, have been identified within amino acid residues 456 to 933, 517 to 630, and 633 to 933 of the protein (SEQ ID NO:1), with at least one distinct binding region within TPO located from amino acid residues 592 to 613 (SEQ ID NO:3). The identification and production of these localized epitopes/epitopic regions provide specific diagnostic reagents for autoimmune thyroid disease.

Abstract:
Mammalian melanin-concentrating hormone (MCH) is isolated from rat tissue, purified and characterized. These MCH peptides are useful for treating skin disorders, for suppressing the proliferation of skin tumor cells, such as melanomas in mammals, and for modulating the secretion of ACTH. Generally, peptides are provided which have the following formula: ##STR1## or which are naturally occurring homologs of the peptide with said formula. The peptides which are the naturally occurring MCH homologs of mammalian species other than rat can also be obtained using the materials disclosed, as demonstrated specifically with human MCH, which is found to have the same structure as rat MCH. Also disclosed are the amino acid sequences of, and the nucleotide sequences of the cDNAs which encode, the putative precursors of rat MCH and human MCH. These precursors may also include one or more biologically active peptides N-terminally of the mature MCH's. Among these peptides, which are thought to be formed from the MCH precursors, are the peptide with the sequence H-Glu-Ile-Gly-Asp-Glu-Glu-Asn-Ser-Ala-Lys-Phe-Pro-Ile-NH.sub.2, which is cross-reactive with antibodies against alpha-MSH and CRF, and the peptide with the sequence H-Gly-X.sub.NGE -Phe-Pro-Ala-Glu-Asn-Gly-Val-Gln-Asn-Thr-Glu-Ser-Thr-Gln-Glu-OH, wherein X.sub.NGE is Pro-Ala-Val or Ser-Val-Ala, which is cross-reactive with antibodies against GRF.
Abstract:
A pharmaceutical composition is described, which contains a fraction consisting of low molecular proteins and/or oligo peptides, and a yellow fraction containing riboflavine, which is associated with organ specific oligo peptides, which fractions are obtainable by fractionation of thymus extract. This composition has a significant immuno stimulating activity, and can be used for the treatment of immuno deficiency diseases, as for example, for T-cell-deficiencies.
Abstract:
Medicinal compositions containing epidermal growth factor are stabilized against loss of biological activity in the presence of moisture by including in said compositions a stabilizing amount of water-soluble cellulose polymer, preferably methylcellulose or a hydroxy alkylcellulose such as hydroxypropyl methylcellulose.
Abstract:
An improved process for purifying proteins, particularly proteins having molecular weights in excess of 12,000 involves novel applications of high performance liquid chromatography on a preparative scale to provide homogeneous end product in excellent yield. In an embodiment of the process, human interferon is produced as a homogeneous protein.
Abstract:
An improved immunoassay for the polypeptide hormone thymosin .alpha..sub.1 is described. The assay employs an improved antibody which is elicited by an immunogen which has been prepared by coupling [Tyr.sup.1 ]-thymosin .alpha..sub.1 to an immunogenic carrier protein using a bifunctional diazonium coupling agent.
Abstract:
Mixtures containing an anterior pituitary hormone such as growth hormone or prolactin are treated to produce relatively pure hormone by a process comprising eluting the mixture through an ion-exchange column followed by fractionation of the eluent on an isoelectric focusing column. Fractions at the isoelectric point of the specific anterior pituitary hormone can be pooled, dialyzed with sterile water, and then lyophilized. The identity of the resulting product can be confirmed by electrophoretic analysis on sodium dodecylsulfate gel, immunodiffusion on an Ouchterlony plate, or both.
