Seeds are often thought of as repositories of various ingredients. The composition of plant seeds is rich in polysaccharides, lipids, and many secondary metabolites, while these tissues are usually low in protein. Proteins are not the main components of the seed, they are often aggregated or combined with other components, such as cell wall material or starch grains. The proteins in grain seeds are generally divided into four categories based on their solubility criteria: albumin, globulin, glutelin, and gluten.

CD BioSciences devoted to plant biology research. We provide our customers with high-quality plant seed protein extraction and purification services. Our service can facilitate the further study of regulation and metabolism mechanisms in seed growth and development.

• Extraction of amphiphilic proteins from seeds
• Extract the protein stuck on the surface or inside the starch granule of seed endosperm

Preparation Method of Plant Seed Protein

Extraction of seed protein by alkali extraction method

Separation of seed protein by air classification method

Separation of seed protein by tribostatic separation method

Application Fields

• Explore the mechanism of seed protein in the process of seed dormancy and germination.
• Explore the mechanism of seed protein involved in seed-environment interaction.
• Develop antibacterial drugs, peptides extracted from plant seeds have antimicrobial properties and can be applied in the biomedical field.
• Cultivate high-quality seeds for agricultural and forestry crops.

Notification for Sample Preparation and Handling

In vacuum-sealed packaging.

It is best to reduce the seed moisture to less than 8%.

Weight of seeds ≥ 2 g, sample repetition times ≥ 6.

Our Advantages

• We can extract proteins from seed samples of various plants with high starch content.
• We have advanced equipment and alternative methods to extract protein from tough seeds.
• We can extract specific seed proteins such as albumin, globulin, gliadin, and glutenin.
