摘要:
The invention relates to polypeptides wlth amino acid sequences spanning position 61 of the normal and the mutant ras proteins, their preparation, the utilization of such polypeptides to prepare immunogenic compositions utilizing such polypeptides covalently linked to immunogenic carrier materials, the production of antibodies elicited by such polypeptides, and to immunoassays and the use of immunochemical methods employing such antibodies to determine the presence of the p21TLeu61 transforming protein.
摘要:
A liquid phase peptide synthetic method which uses (1) Fmoc as the protecting group for the non-side chain amino functionality, (2) ammonia, a primary or secondary amine to remove the Fmoc protecting group, and (3) substituted carbodiimide as the coupling agent for the C to N synthesis of peptides or peptide derivatives in a proper organic solvent.
摘要:
Es werden SLO Peptidantigene beschrieben. Diese Peptidantigene sind zur Bestimmung von SLO-Antikörpern, als Immunogene zur Herstellung von Antikörpern gegen SLO und als Vakzine zur Herstellung von Impfstoffen gegen SLO geeignet.
摘要:
Process for the preparation of modified proteins comprising the coupling of a first peptide segment having a haloacyl group at the N-terminus thereof with a second peptide segment having a carbonylthiol group at the C-terminus thereof are disclosed. Novel modified proteins produced by the process are also disclosed.
摘要:
Single-chain analogs of the naturally occurring two chain peptide monellin retain the sweetening properties of the natural protein and are stable under conditions which would otherwise destabilize the native peptide. A covalent linker joins peptides corresponding to portions of the A and B chains of the naturally occurring protein.
摘要:
There is disclosed a solid surface, such as the surface of a rod or pin, for use in the synthesis of polymeric compounds such as peptides. The surface comprises an active region and an inactive region being positioned such that, in use, it is below the surface of the reaction liquid in a reaction well, irrespective of minor variations in liquid levels between various wells so as to eliminate the formation of deletion compounds. There are further described such surfaces for the formation of relatively large quantities of compound wherein the active region has a higher surface area/volume ratio than that of a cylinder of corresponding volume.
