Angiogenesis is associated with several pathological disorders as well as with normal physiological maintenance. Components of vascular basement membrane are speculated to regulate angiogenesis in both positive and negative manner. Recently, we reported that tumstatin (the NC1 domain of alpha 3 chain of type IV collagen) and its deletion mutant tum-5(More)
Antiangiogenic therapy, although effective in shrinking tumors, has not yet been established as a standalone treatment for cancer. This therapeutic limitation can be overcome by combining angiogenesis inhibitors with chemotherapeutic agents. NM-3, a small molecule isocoumarin, is a recently discovered angiogenesis inhibitor. Here we demonstrate that NM-3(More)
Immunogenicity testing for PEGylated biotherapeutics should include methods to detect both anti-protein and anti-PEG antibodies (anti-PEG). Although some methods have been published for the detection of anti-PEG antibodies, the information is incomplete and, in some cases, reagents used (such as Tween-20) are known to interfere with detection. This rapid(More)
Achieving the required sensitivity can be a challenge in the development of ligand binding assays for pharmacokinetic (PK) determinations of biotherapeutics. To address this need, BioScale’s Acoustic Membrane Microparticle (AMMP) technology was evaluated for the quantification of a PEGylated domain antibody (dAb) biotherapeutic. Previous uses of this(More)
The acoustic membrane micro particle (AMMP) technology has been used to quantify single analytes out of multiple sample types. In this study the technology is used to reveal molecular interactions of components of kinase pathways. Specifically, the downstream kinase activity of the EGFR receptor in the presence or absence of EGFR inhibitors is investigated.(More)
