A polyelectrolyte-surfactant complex, a method of removing a toxic substance from contaminated soil or contaminated groundwater using a polyelectrolyte-surfactant complex and a method of making a polyelectrolyte-surfactant complex. The polyelectrolyte-surfactant complex is made from a complexated recombinant intrinsically disordered protein that has been electrostatically conjugated to an anionic surfactant to provide enhanced liquid-liquid phase separation properties.

The present invention provides capsular polysaccharides from Streptococcus pneumoniae serotypes identified using NMR. The present invention further provides polysaccharide-protein conjugates in which capsular polysaccharides from one or more of these serotypes are conjugated to a carrier protein such as CRM197. Polysaccharide-protein conjugates from one or more of these serotypes may be included in multivalent pneumococcal conjugate vaccines having polysaccharides from multiple additional Streptococcus pneumoniae serotypes.

Provided are methods for linking polypeptides (including peptides and proteins) to other moieties using radical imitated thiol-ene chemistries, for example, modifying a polypeptide by introducing reactive thiol groups and reacting the thiol groups with olefin-containing reagents or alkyne-containing reagents under conditions that support radical thiol-ene or thiol-yne reactions. The reactive thiol groups have greater activity for radical thiol-ene reactions that a cysteine thiol group, including thiol groups that are separated from the peptide backbone by at least two carbon atoms, for example, the thiol group of a homocysteine residue. Also provided are compositions and biomaterials containing the linked polypeptides, for example, peptide and protein conjugates, and thiol-ene based biocompatible hydrogel polymers, and their uses in the medical field.

Materials and methods for protein purification, and particularly for protein purification by ammonium sulfate precipitation, are provided herein.

A method for producing a natural formaldehyde-free adhesive for wood panels, which improves the crosslinking reactions between the crosslinking agent and the binding agent, comprising reacting a plant protein selected from soy, lupine and legumes, together with a crosslinking agent selected from 100% of an oxidized saccharide or a combination of an oxidized saccharide and an unoxidized or pure saccharide; the method comprises the steps of: an oxidation step of a saccharide; a preparation step of plant protein, in which the plant protein is reacted with a chaotropic agent or alkali or by temperature control or a combination of these conditions; and a mixing step.
