Did You Know...
...that the Eveready Battery began as an invention called the "electric flowerpot," which was a tube with a battery and light bulb inside? The idea was to fasten this gizmo to the side of a flowerpot so it would illuminate the flowers from the bottom. The idea died on the vine and the businessman who licensed the flower pot, Conrad Huber, was left with a pile of useless tubes -- until he found a way to market them as batteries to light the world!

| Number | Title | Issue Date |
| 5324822 | Method of isolating a CA 195-like immunoreactive antigen from human amniotic fluid A method of isolation of a material with similar immunological properties to CA-195 from human amniotic fluid has been disclosed. This material can be substituted for CA-195 in many processes, for example in the preparation of analytical control materials... | 06/28/1994 |
| 5306811 | Squamous cell carcinoma-like immunoreactive antigen from human female urine A squamous cell carcinoma-like (SCC-like) immunoreactive antigen has been identified in human female urine. This material appears to perform the same as and quite likely have the same composition as squamous cell carcinoma associated antigen (SCC) which i... | 04/26/1994 |
| 5283288 | PVC coatings for electrodes This invention involved the discovery of novel polymers and a process for their preparation. The polymers were prepared by the nucleophilic substitution, at room temperature, of PVC with substituted alkyltrialkoxysilanes, which can be cured at room temper... | 02/01/1994 |
| 5241070 | Nucleophilic polysubstituted aryl acridinium esters and uses thereof This invention is directed to novel nucleophilic polysubstituted aryl acridinium esters and to novel conjugates thereof. The novel nucleophilic polysubstituted aryl acridinium esters and novel conjugates thereof are useful in biological assays, including ... | 08/31/1993 |
| 5227489 | Stable hydrophilic acridinium esters suitable for liposome encapsulation A method for the detection of an analyte in a fluid sample using liposomes encapsulating acridinium esters (lumisomes). Hydrophilic polysubstituted aryl acridinium esters are useful as chemiluminescent markers and can be encapsulated within liposome vesic... | 07/13/1993 |
| 5196349 | Immunoassays for thyroid hormones using thyroglobulin Immunoassays for measuring thyroid hormones such as thyroxine(T4) and triiodothyronine(T3) are carried out by incubating a serum sample with either (a) unlabeled thyroglobulin and a labeled antibody to a thyroid hormone or to thyroxi... | 03/23/1993 |
| 5110932 | Polysubstituted aryl acridinium esters The present invention relates to novel acridinium esters which are useful as luminescent labels in specific binding assays such as immunoassays or nucleic acid hybridization assays. More particularly, polysubstituted aryl acridinium esters are highly stab... | 05/05/1992 |
| 5094785 | Process for stabilizing liposomes The present invention relates to a process for forming stable, uniform unilamellar or oligolamellar liposomes which encapsulate a macromolecule. However, unlike prior processes, the present method maintains a temperature below the phase transition tempera... | 03/10/1992 |
| 5093270 | Method for enhancing signal release from liposomes using water-miscible alcohols A method for releasing encapsulated marker molecules from within liposomes comprises contracting the liposomes with an effective amount of a water-miscible alcohol. The chemiluminescence of acridinium esters is enhanced by oxidizing the acridinium ester i... | 03/03/1992 |
