CD BioSciences devoted to plant biology research. We provide our customers with high-quality plant protein extraction and purification services .

The material composition and protein proportion vary in different parts of the plant, and the chosen protein extraction method is also different. The nature of plant protein determines that it dissolves in water, dilute alkali, dilute acid and dilute salt solutions, so we use different solvents to extract plant protein.

Service Content

Plant Leaf Protein Extraction and Purification Service

The use of protein extracted from plant leaves is of great help to scientific research and food applications. We use the salting-out method, organic solvent method, and isoelectric point precipitation method to provide customers with high-quality plant leaf protein preparation services. We are able to extract protein from a wide range of woody and herbaceous plants.

Plant Fruit Protein Extraction and Purification Service

Plant fruits contain a variety of enzymes composed of soluble proteins. These enzymes are closely related to fruit growth and development, maturation and senescence, disease resistance, and stress resistance. We use organic solvent precipitation and phenol solution methods to extract proteins from melon, stone fruit, citrus and berries. It is beneficial for customers to further research the regulatory mechanism of protein in fruit on plant physiological and biochemical metabolism.

Plant Seed Protein Extraction and Purification Service

The protein within the seed is crucial for the growth, development and metabolism of the seed. We use dry method and wet method to extract protein from food crop seeds, oil seeds, cash crop seeds, grass seeds, flower seeds, etc. The extraction of seed protein can deepen the understanding of the complex biological process of plant seed development, and provide help for improving the related economic traits of crops.
