Latest Patents

One of Sundberg's latest patents is titled "Hydrolyzable fluorescent substrates for phosphatases and analytical use." This invention involves hydrolyzable substrates for acid and alkaline phosphatases that comprise blocked dye moieties. When cleaved from the substrate during hydrolysis, these moieties provide fluorescent dyes with maximum absorptions above about 530 nm and maximum fluorescent emissions at least about 580 nm. The dyes are blocked prior to hydrolysis with a phosphono or thioxophosphono group or a salt thereof. These substrates can be utilized in analytical determinations of acid or alkaline phosphatase or in competitive binding reactions to identify immunologically reactive substances.

Another significant patent is "Calcium complexing dyes and their use in analytical compositions." This invention features novel chromogenic derivatives of 1,2-bis-(o-aminoaryloxy)ethane-N,N,N',N'-tetraacetic acid, which are useful for determining calcium ions in both solution and dry assays. The compounds include a dye moiety directly conjugated to the acetic acid substituted-nitrogen atom, allowing them to exhibit maximum absorbance at a wavelength generally greater than 400 nm before complexation. Upon complexation with calcium ions, the absorbance shifts to a shorter wavelength.
