Fibroblast growth factor-2 (FGF2) plays a major role in angiogenesis. The pattern recognition receptor long-pentraxin 3 (PTX3) inhibits the angiogenic activity of FGF2. To identify novel FGF2-antagonistic peptide(s), four acetylated (Ac) synthetic peptides overlapping the FGF2-binding region PTX3-(97-110) were assessed for their FGF2-binding capacity. Among(More)
This study investigates the applicability of the protein A Mimetic (PAM) affinity ligand, obtained from the screening of a multimeric combinatorial peptide library, in immunoglobulin isolation from serum. To avoid protease degradation, the ligand has been substituted by its inverso form, named D-PAM, synthesized by replacing all amino acids with the(More)
Chicken avidin and bacterial streptavidin are widely employed in vitro for their capacity to bind biotin, but their pharmacokinetics and immunological properties are not always optimal, thereby limiting their use in medical treatments. Here we investigate the biochemical and biological properties of a new modified avidin, obtained by ligand-assisted sodium(More)
Human CD105 antigen, a type I integral membrane glycoprotein, is expressed as homodimer and oligomer by human endothelial cells, and forms a heteromeric association with TGF-beta signaling receptors I and II. Several mutations of CD105 antigen gene are involved in a vascular disorder known as hereditary hemorrhagic telangiectasia type 1. The proposed(More)
In this work we describe the production of site-specific biotinylated human myeloid differentiation factor 88 (MyD88). A vector containing a coding sequence for a peptide derived from the carboxyl terminus of the Klebsiella pneumoniae oxalacetate decarboxylase alpha subunit was used to allow expression and biotinylation of MyD88 in Drosophila melanogaster(More)
