This study investigated the use of a newly developed chitosan-Ca pectinate microbead formulation for the colon-targeted delivery of anti-A/B toxin immunoglobulin of egg yolk (IgY) to inhibit toxin binding to colon mucosa cells. The effect of the three components (pectinate, calcium chloride, and chitosan) used for the microbead production was examined with(More)
A bifunctional RGDTAT peptide-modified PEG-PAMAM dendrimer conjugate RGDTAT-PEG-PAMAM (RTPP) was established for the targeted treatment of αvβ3-overexpressing tumor cells. The RGDTAT peptide was synthesized and attached to PAMAM using PEG to construct the RTPP conjugate. The methotrexate (MTX) encapsulated RTPPM complex was prepared and characterized by(More)
