We further evaluated the efficiency of the new PRP preparation device by comparing it with that of a commercially available kit (RegenKit-THT).

This copolymer showed no cytotoxicity against cell viability or hemolysis. We used a new cationic copolymer coating on a polyurethane (PU) sponge to promote platelet separation from the blood. Although commercial PRP preparation kits are already available in the market, most of these kits employ centrifugation.

Platelet-rich plasma (PRP) is beneficial for clinical applications in various medical fields. These results are of importance in designing polyelectrolytes with a higher affinity to the biolodical (cell) membrane and minimum cytotoxicity and demonstrate the potential of polyampholytes in developing biocompatible polymeric structures. Cytotoxicities of polyampholytes are one to two orders of magnitude less than the cytotoxicity of a pure polycationic polymer with the same degree of polymerization. By varying a length of вЂ“(CH2)nвЂ“ spacer in the betaine group, different behaviors of polybetaines in a suspension of anionic liposomes can be realized: from no interaction to complexation followed by significant structural reorganization in the liposomal membrane. The polymers were complexed with anionic mixed lipid membranes, liposomes, and Langmuir monolayers.

In this paper, we describe three series of polyampholytes synthesized via quaternization of poly(4-vinylpyridin) by П‰-bromocarboxylic acids and alkyl bromides: (1) with cationic and anionic groups in each unit (polybetaines), (2) with betaine and cationic groups, and (3) with betaine and pendant alkyl groups. Although additional studies would be needed in order to elucidate the mechanism of PDMAEMA mediated activation of platelets, our manuscript provides important information on the hemoreactivity of FF PDMAEMA.Д¬opyright В© 2015. Activation of platelets was also noticed in whole blood with the expression of P-selectin and fibrinogen on platelet surface. PDMAEMA (1-20Ојg/mL) exerted a concentration dependent proaggregant effect with a biphasic aggregation of washed platelets. This in vitro study highlighted that platelets display higher affinity for this polycation compared to red blood cells (RBCs), with an adsorption isotherm characteristics of a specific saturable binding site.

To gain more insight into this polycation hemoreactivity, we followed the binding kinetics of a free form (FF) of fluorescein labelled PDMAEMA (below 15 kDa) in normal human blood using flow cytometry. As expected for other cationic carriers, intravenous administration of PDMAEMA can result in its ionic complexation with various negatively charged domains found within the blood. Poly(2-dimethylamino)ethyl methacrylate (PDMAEMA) is an attractive polycation frequently proposed as a non-viral vector for gene therapy.
