The invention relates to carrier complexes and methods for delivering molecules to cells. The carrier complexes comprises a molecule and an aromatic cationic peptide in accordance with the invention. In one embodiment, the method for delivering a molecule to a cell comprises contacting the cell with a carrier complex. In another embodiment, the method for delivering a molecule to a cell comprises contacting the cell with a molecule and an aromatic cationic peptide.

The present disclosure relates to methods and compositions comprising derivatized-chitosan polyplexes reversibly coated with a polyanion-containing block co-polymer for the localized expression of IL-12 in mucosal tissues, preferably in combination with an IFN-1 activator/inducer, for use in cancer immunotherapy.

A biomagnetic microsphere and a preparation method and a method for protein isolation and purification therefor. The outer surface of a magnetic microsphere body of the biomagnetic microsphere has at least one liner polymer with a branched chain; one end of the linear polymer with a branched chain is covalently coupled to the outer surface of the magnetic microsphere body, and other parts are free on the outer surface of the magnetic microsphere body; a backbone of the linear polymer is a polyolefin backbone, and no cross-linking agent is required in the backbone forming process of the linear polymer. The prepared biomagnetic microsphere can implement efficient elution of target proteins and effectively reduce the retention time and retention ratio of the target proteins, and it is easy to operate and widely used.

Microbes can be genetically modified to express biomolecules that are beneficial to mammals and/or to reduce, or eliminate, expression of harmful virulence factors. The growth and viability of such genetically modified microbes can optionally be controlled by inducible promoters that regulate the expression of proteins that are essential to their growth and survival. Compositions comprising such genetically modified microbes as well as methods of making and using the same are disclosed herein.

The present disclosure provides compositions with a modulating gene expression and methods for modulating transcription.
