The present invention relates generally to a method for extracting cannabis-derived proteins from cannabis plant material, including the preparation of samples of extracted cannabis-derived proteins for proteomic analysis and methods for analysing a cannabis plant proteome.

Provided herein are compositions with enhanced protein specific activity, protein combinations and methods for the preparation thereof.

The present disclosure provides materials and methods for determining the presence of an N-terminal modification on a therapeutic protein, and/or the efficiency of N-terminal modification, such as PEGylation, at the N-terminus of a therapeutic protein such as Filgrastim (wherein the PEGylated version is therefore Pegfilgrastim).

A liquid or dried granulated milk clotting aspartic protease enzyme composition and process for isolating a milk clotting aspartic protease enzyme of interest.

Provided herein are compositions with enhanced protein specific activity, protein combinations and methods for the preparation thereof.

A liquid or dried granulated milk clotting aspartic protease enzyme composition and process for isolating a milk clotting aspartic protease enzyme of interest.

Provided herein are compositions with enhanced protein specific activity, protein combinations and methods for the preparation thereof.

Disclosed is a composition of a collagen peptide and an elastin peptide, method of producing the same and use thereof. The composition of the present disclosure consists of a collagen peptide and an elastin peptide; the collagen peptide is prepared by enzymatic hydrolysis of a collagen material with pepsin or trypsin, and the elastin peptide is prepared by enzymatic hydrolysis of an elastin material with papain and/or protease Protamex. In the present disclosure, an elastin peptide and a collagen peptide with molecular weight in a specific range are prepared by specific processes, and the composition composed of the two at a suitable ratio can simultaneously and significantly increase the amount of the elastin and collagen in a damaged skin in a small usage amount, and significantly increase the content of hyaluronic acid and hydroxyproline while decrease the content of MMP3, meanwhile, inhibit skin inflammatory factors.
