Patent number: 8865412Abstract: Methods and assays for oversulfated glycosaminoglycans are provided. In an embodiment, the present disclosure provides a method for detecting oversulfated glycosaminoglycan (OS-GAG) in a heparin sample. The method comprises placing the heparin sample onto a support comprising immobilized heparin and contacting the heparin sample on the support with a binding compound that attaches to the heparin and forms a heparin-binding compound complex. The binding compound also has a greater affinity for attaching to the OS-GAG than to the heparin in the heparin sample and forms an OS-GAG-binding compound complex. The method can further comprise detecting an amount of the heparin-binding compound complex on the support, and determining an amount of OS-GAG in the heparin sample based on the amount of the heparin-binding compound complex on the support.Type: GrantFiled: May 28, 2008Date of Patent: October 21, 2014Assignees: Baxter International Inc., Baxter Healthcare S.A.Inventor: Shawn F.

Patent number: 8383107Abstract: A phage-displayed library of llama single heavy domain antibodies (sdAbs) was enriched for species that selectively bind to and are internalized by human cerebromicrovascular endothelial cells (HCEC). From the enriched library, two sdAbs were selected, sequenced, subcloned, and expressed as fusion proteins with c-myc-His5 tags (His5 is SEQ ID NO:101). Similarly as phage-displayed sdAbs, these soluble tagged sdAbs were shown to selectively bind to HCEC and to transmigrate across in vitro human blood-brain barrier (BBB) model. In contrast to an unrelated llama sdAb, these sdAbs were also detected in the brain after i.v. injection into mice. These small (˜13 kDa) antibody fragments have essential characteristics of brain-specific delivery vectors and can be used to facilitate drug transport across the BBB.Type: GrantFiled: March 21, 2011Date of Patent: February 26, 2013Assignee: National Research Council of CanadaInventors: Arumugam Muruganandam, Jamshid Tanha, Saran Narang, Danica Stanimirovic
