The present invention relates to a recombinant vector carrying cellulose-binding domain 3 and a method for separating a target protein using the recombinant vector. The protein isolating method of the present invention can easily separate a fusion protein containing a target protein by using the recombinant vector to bind a transformed plant body to cellulose and can effectively isolate the target protein from a cellulose-binding domain by treating the fusion protein with enterokinase, thus being expected to find industrial applications in various fields.

Recombinant vector carrying cellulose binding domain and method for isolating and purifying protein, using same vector

A recombinant vector for transforming a plant, a plant transformed with the recombinant vector, a plant-made classical swine fever virus antigen pmE2 protein expressed in the plant and uses thereof is provided. By using a recombinant vector having a polynucleotide encoding a GP55 protein of CSFV according to the present invention; and a polynucleotide encoding a cellulose-binding domain protein; and a plant transformed with the recombinant vector, a plant-made classical swine fever virus antigen pmE2 protein may be produced with high efficiency, and has higher safety and stability than those achieved by other production methods. Also, since the plant-derived classical swine fever virus antigen protein pmE2 has a cellulose-binding domain (CBD) protein, it may be usefully used as an effective marker to determine a virus exposure pathway and an antibody producing pathway.

Vaccine composition for classical swine fever from plant and manufacturing method thereof

The present invention provides a plant expressing a target protein, a method of preparing the same and a method of preparing a composition for oral administration of a biopharmaceutical using the same. A target protein expression system using plant cells according to the present invention solves conventional problems in plant cell culture, provides a method of producing a large quantity of target proteins including a biopharmaceutical protein and allowing a target protein to have a resistance to a protease present in a digestive organ, and therefore is very effective to enable commercialization of plant-derived biopharmaceuticals.

Method of highly expressing target protein from plant using RbcS fusion protein and method of preparing composition for oral administration of medical protein using target protein expression plant body

The present invention relates to a method of isolating a protein containing a cellulose binding domain from plants using various structures of cellulose and/or variants thereof. According to the method of isolating a protein, as a high affinity cellulose binding domain is used, a high purity recombinant protein is rapidly and effectively isolated in large quantities at low cost, and thus can be applied in various industrial fields.
