摘要:
This invention is directed to a method for isolating and/or purifying one or more taxanes from materials comprising taxanes. In one embodiment, the method comprises the steps of: (a) treating a taxane containing material with an amino containing material attached to a solid matrix, such as a polyethyleneimine-bonded silica chromatographic resin; (b) eluting the desired taxane compound from the resin; and (c) recovering the eluted taxane compound.

The present invention relates to a method of producing sesquiterpene lactones of the thapsigargin family, the method comprising the steps of: (a) culturing plant cells of the genus Thapsia in a nutrient medium in a suspension cell culture, wherein the cells produce one or more sesquiterpene lactones of the thapsigargin family; and (b) recovering one or more sesquiterpene lactones of the thapsigargin family produced in (a). The present invention further relates to a suspension cell culture comprising plant cells of the genus Thapsia, wherein the plant cells are capable of producing one or more sesquiterpene lactones of the thapsigargin family and to a plant cell biomass comprising plant cells of the genus Thapsia obtained from said suspension cell culture.
摘要:
Disclosed is a method of crystallizing a taxane comprising combining the taxane and methylene chloride to obtain a solution and adding an anti-solvent to the solution to obtain a crystalline taxane, wherein the anti-solvent is selected from the group consisting of hexane and heptane.
摘要:
A method for the secretory production of a glycoprotein having a human-type sugar chain, comprising a step of introducing a gene of an enzyme capable of performing a transfer reaction of a galactose residue to a non-reducing terminal acetylglucosamine residue, and a gene of heterologous glycoprotein, to obtain a transformed plant cell, a step of culturing the plant cell, and a step of recovering the culture medium of the plant cell.

摘要:
The present invention provides a method for manufacturing a glycoprotein having a human-type sugar chain comprising a step in which transformed plant cell is obtained by introducing to a plant cell the gene of glycosyltransfetase and the gene of an exogenous glycoprotein, and a step in which the obtained transformed plant cell is cultivated.
摘要:
This invention provides for the plant production of immunoglobulins, wherein at least a portion of the glycans attached to the immunoglobulins lack fucose. The invention also provides the constructs; plasmids; vectors; transformed plant cells, transformed plant calli; transformed plant tissues (e.g., leaves, seeds, tubers, etc.); transformed whole plants used to produce such immunoglobulins; methods of producing the immunoglobulins; the immunoglobulins produced by the disclosed methods; and the use of such immunoglobulins.
