20110287408 | Preparation of Micro-Porous Crystals and Conjugates Thereof - A conjugate comprising a dye-labeled microporous crystal, a stop-cock moiety, and covalently bound thereto an affinity binding agent is disclosed. The dye-labeled microporous crystal is a zeolite crystal, such as a zeolite L crystal, having a large number of channels in its interior into which the dye is loaded. The stop-cock moiety can be functionalized with an amino group to which a carboxyester group can be attached. The affinity binding agent allows for the binding to a biological moiety. The conjugate of the moiety can be used in in-vivo and/or in-vitro imaging applications. | 11-24-2011 |
20120149019 | USE OF A BIS-MALEIC ANHYDRIDE CROSS-LINKING AGENT FOR FIXATION OF A CELL OR TISSUE SAMPLE - The present disclosure relates to novel bis-maleic anhydrides and to the surprising discovery that bis-maleic anhydride cross-linking agents can be used for preservation/fixation of a cell or tissue sample. Various bis-maleic anhydride cross-linking agent scan be used in methods requiring fixation of a cell or tissue sample. These reagents and methods are especially useful in procedures that require that the fixation agent be removed in order to facilitate analysis with other reagents. The inventive reagents and methods make it easier to reliably assay for various proteins, a nucleic acid and the like using analytical methods such as like immunohistochemistry, fluorescence in situ hybridization, RT-PCR, and the like. | 06-14-2012 |
20130023055 | METHODS FOR MEASUREMENT OF CALCIUM IONS - Reagents and methods for determination of calcium within a sample. Specific embodiments include a reagent for determination of calcium comprising a mono-nitro substituted BAPTA-type chelator (BAPTA=1,2-bis(2-aminophenoxy)ethane-N,N,N′,N′-tetraacetic acid). Methods for accurate determination of calcium in a sample, such as a blood, whole blood, plasma or serum or any other aqueous liquid sample including cerebrospinal fluid, lymph, salivary juice or urine. Embodiments are also useful for clinical diagnoses. | 01-24-2013 |
