protein isolation and purification from plants

Rapid one-step protein purification from plant material

May 01, 2004· Beyond the rewards of plant genome analysis and gene identification, characterisation of protein activities, post-translational modifications and protein complex composition remains a challenge for plant biologists. Ideally, methods should allow rapid isolation of proteins from plant material achieving a high degree of purity. We tested three purification strategies based on the eight-amino

Purification, Characterization, and Plant Physiology

Protein Purification. Pokeweed (Phytolacca americana) plants were grown in the greenhouse of Peking University.For isolation and purification of the AMP from pokeweed seeds (Pa-AMP-1), 20 g of seeds were collected. The seeds were ground into powder and suspended in approximately 20 mL of 4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid (HEPES) buffer (25 m m, pH 8.0) containing 1 m m NaCl.

Isolation of nuclear proteins PubMed

Although Arabidopsis thaliana is the prime model system for plant molecular genetics, proven protocols for biochemical fractionation are often best established for other plant species. In this chapter, we present methods for the isolation of nuclei, nuclear proteins, and nuclear protein fractions that have been adapted for Arabidopsis.

Overview of Protein Purification and Characterization

Protein purification has an over 200-year history: the first attempts at isolating substances from plants having similar properties to “egg albumen,” or egg white, were reported in 1789 by Fourcroy. Many proteins from plants were purified in the

Protein The isolation and determination of proteins

The isolation and determination of proteins. Animal material usually contains large amounts of protein and lipids and small amounts of carbohydrate; in plants, the bulk of the dry matter is usually carbohydrate.If it is necessary to determine the amount of protein in a mixture of animal foodstuffs, a sample is converted to ammonium salts by boiling with sulfuric acid and a suitable inorganic
