  • Patent number: 5885784
    Abstract: Materials and compositions for making triglyceride controls, calibrators and standards are described. The materials are mono- and di- and tri- glycerides of medium length fatty acids mixed into compositions of human serum or other protein solutions to form stable, miscible solutions suitable for use as controls, calibrators and standards in clinical chemistry for measurement and quality control in assays for triglycerides. The materials described have been used as vehicles for oil-soluble, water-insoluble pharmaceuticals and as facial emollient oils for cosmetics, and as such are safe, functional, stable, rancid-resistant and very inexpensive compared with pure materials synthesized or described previously.

  • Patent number: 4363634
    Abstract: A new and useful process is disclosed for manufacturing a device for use in a bioprocess, comprising: (a) providing solid support means insoluble in water or organic solvent solutions; (b) coating said solid support means with water-based polymeric film means capable of applying one or more biomaterials; and (c) adsorbing or covalently bonding at least one functional biomaterial to said polymeric film means. The polymeric film means, for example, can be used to coat antigens, antibodies, haptens, enzymes, living bacteria, yeasts, etc. (i.e., biomaterials) to a glass (or other) support material, e.g., a glass tube, with surprising retention of the biomaterial's essential characteristic properties. The solid support means include but are not limited to those comprising glass, ceramics, metals, polymers and woods. The device of the invention is particularly useful in various immunoassays using a solid support for separation of phases.

  • Patent number: 4152411
    Abstract: A new diagnostic labeled spine tool is disclosed for use in immunoassay techniques, e.g., determination of a component of the antigen-antibody reaction. The new tool is a labeled-spine material product of the formula ##STR1## where R is an organic group labeled with a radioisotope, fluorescent group, lysis-initiating compound, enzyme, or other suitable marker material; T.sub.1 and T.sub.2 are any of --CH.sub.3, ##STR2## --CH.sub.2 OH, --Ch.sub.2 SH, and --NH.sub.2 ; X is selected from the group consisting of (CH.sub.2).sub.m, where m is an integer from 0 to about 10, phenylene, hydroxyl-substituted phenylene, halogen-substituted phenylene, alkyl substituted phenylene or aminated phenylene groups;A is 0, 1 or 2;B is 2-a, with the proviso that there be at least two R groups in the product; andN is a number from 1 to about 100,000The new tool provides higher specific activity for labeled substances thus facilitating determination of the desired compound.
