Separation and Purification of ε-Poly-L-lysine with Its Colorimetric Determination Using Dipicrylamine.

Efficacy of ε-Poly-L-lysine as an Antibacterial Additive for Platelets Stored at Room Temperature

Determination of Adsorption Isotherm for L-Lysine Imprinted Polymer

The optimization of adsorption-based operations requires an accurate model to represent the separation process. In the present study, single-component adsorption data of L-lysine on its imprinted polymer were fitted to Freundlich, Langmuir-type and Jovanovic-type models. L-Lysine imprinted polymer (LLIP) was prepared by free radical solution polymerization. The best estimate of the parameters o...

Study of the inhibitory effects of N-heterocycles, magnesium oxide nanoparticles, nisin and poly-L-lysine on Enterobacter aerogenes (hospital pathogen)

Background: Enterobacter aerogenesis one of the causes of hospital-acquired infections, which its standard strains quickly become resistant to the antibiotics. The discovery of new inhibitory agents against this pathogen is constantly expanding. In this study, the inhibitory effects of several synthetic chemical compounds including magnesium oxide nanoparticles and thiazole, imidazolidine and t...

Preparation of Plasminogen by Affinity Chromatography

Background: Plasminogen is one of the compounds derived from human plasma. Activation of plasminogen produces plasmin. Plasmin is able to lyse fibrinogen, fibrin, and some other human plasma proteins. The aim of the present work was to study the separation of human plasminogen by affinity chromatography using gel lysine Sepharose. Materials and Methods: Normal human plasma was used as the...

In vitro Labeling of Neural Stem Cells with Poly-L-Lysine Coated Super Paramagnetic Nanoparticles for Green Fluorescent Protein Transfection

Background: The magnetic nanoparticle-based transfection method is a relatively new technique for delivery of functional genes to target tissues. We aimed to evaluate the transfection efficiency of rat neural stem cell (NSC) using poly-L-lysine hydrobromide (PLL)-coated super paramagnetic iron oxide nanoparticles (SPION). Methods: The SPION was prepared and coated with PLL as transfection agent...
