Practical syntheses of dyes for difference gel electrophoresis
摘要:
The three dyes (two indocyanine and one berizoxazolium) useful in difference gel electrophoresis-methyl Cy5 1, propyl Cy3 2, and the benzoxazolium dye Cy2 3-and their NHS esters have been prepared by efficient routes in good overall yield from inexpensive precursors.

the HyCoSuL approach, we designed and synthesized novel and selective fluorogenic substrates for each of these three constitutive 20S proteasome activities and applied them to assess inhibition of proteasome subunits by MG-132 and a clinically used inhibitor bortezomib. Our results confirm the utility of designed substrates in biochemical assays. Furthermore, selective peptide sequences obtained in this

Fluorescent protein conjugates are vital tools in a wide range of scientific disciplines from basic biochemical research to applications in clinical pathology and intraoperative surgery. We report the synthesis and characterization of photoactivatable fluorophores (PhotoTags) based on the functionalization of coumarin, fluorescein, BODIPY, rhodamine B, and cyanine dyes with a photochemically active

report a strategy of utilizing irreversible cysteine cathepsin inhibitor as trapping agent to increase the tumor residence time of receptor-targeted agents. The targeted constructs incorporating these cysteine cathepsin trapping agents were able to form high molecular weight adducts with intracellular cysteine cathepsins, thus achieving superior retention in tumor tissues.
bases; the Fmoc-K2M derivative can be used directly in solid phase peptide synthesis, rendering bPNA+ conveniently accessible. A compact bPNA+binding site of two U6 domains can be genetically encoded to replace existing 6 bp stem elements at virtually any location within an RNA transcript. We thus replaced internal 6 bp RNA stems that supported loop regions with 6 base-triple hybrid stems using fluorophore-labeled
