Water-soluble discrete multi-biotin-containing compounds with at least three (3) biotin moieties are disclosed. The water-soluble biotin-containing compounds may additionally comprise one or more moieties that confer resistance to cleavage by biotinidase or that is cleavable in vitro or in vivo. The discrete multi-biotin-containing compounds may include a reactive moiety that provides a site for reaction with yet another moiety, such as a targeting, diagnostic or therapeutic functional moiety. Biotinylation reagents comprising water-soluble linker moieties are also disclosed and may additionally comprise a biotinidase protective group. Methods for amplifying the number of sites for binding biotin-binding proteins at a selected target using multi-biotin compounds also are disclosed.

immediately adjacent to a single-stranded complementary binding region for the ODN conjugate. The conjugates demonstrated excellent stability in physiologic conditions and stereospecific, hybridization-triggeredalkylation of the synthetic ODN targets. The dependence of the reaction rates on sequence of the duplex target region was in accord with the predicted minor groove binding of the conjugated CPI

bind in the major groove to specific double-helical DNA sequences and have been shown to inhibit the function of targeted genes. Diaziridinylquinones are bifunctional alkylating agents that can form interstrandcross-links in DNA at 5‘-GNC sites. To demonstrate the feasibility of targeted interstrandcross-linking, a diaziridinylquinone−TFO conjugate was prepared from a diaziridinylquinone intermediate
三链体形成寡核苷酸 (TFO) 在大沟中与特定的双螺旋 DNA 序列结合,并已被证明可以抑制靶基因的功能。Diaziridinylquinones 是双功能烷化剂,可在 DNA 的 5'-GNC 位点形成链间交联。为了证明靶向链间交联的可行性,从带有活化酯接头的二氮丙啶醌中间体制备了二氮丙啶基醌-TFO缀合物。描述了通过单一靶向双功能烷化剂进行三链体定向链间 DNA 交联的首次演示。在 pH 6.2 下观察到高达 38% 的链间交联。

The present invention relates to the tagging of Histidine in polypeptides with arylboronic acid tagging reagents. The present invention further describes methods and devices to identify proteins in a sample by isolating and identifying Histidine-comprising peptides from one protein sample or a pool of protein samples. The present invention further describes databases of Histidine-comprising peptides from in silico cleaved proteins and their use in the identification of proteins.

Disclosed is an antibody which binds to olanzapine, which can be used to detect olanzapine in a sample such as in a competitive immunoassay method. The antibody can be used in a lateral flow assay device for point-of-care detection of olanzapine, including multiplex detection of aripiprazole, olanzapine, quetiapine, and risperidone in a single lateral flow assay device.
