摘要:
The immunoglobulins of the present invention are useful therapeutic immunoglobulins against mucosal pathogens such as S. mutans. The immunoglobulins contain a protection protein that protects the immunoglobulins in the mucosal environment.The invention also includes the greatly improved method of producing immunoglobulins in plants by producing the protection protein in the same cell as the other components of the immunoglobulins. The components of the immunoglobulin are assembled at a much improved efficiency. The method of the invention allows the assembly and high efficiency production of such complex molecules.The invention also contemplates the production of immunoglobulins containing protection proteins in a variety of cells, including plant cells, that can be selected for useful additional properties. The use of immunoglobulins containing protection proteins as therapeutic antibodies against mucosal and other pathogens is also contemplated.

摘要:
A method for the stepwise creation of phosphodiester bonds between desired nucleosides resulting in the synthesis of polynucleotides having a predetermined nucleotide sequence by preparing an initiation substrate containing a free and unmodified 3′-hydroxyl group; attaching a mononucleotide selected according to the order of the predetermined nucleotide sequence to the 3′-hydroxyl of the initiating substrate in a solution containing a catalytic amount of an enzyme capable of catalyzing the 5′ to 3′ phosphodiester linkage of the 5′-phosphate of the mononucleotide to the 3′-hydroxyl of the initiating substrate, wherein the mononucleotide contains a protected 3′-hydroxyl group, whereby the protected mononucleotide is covalently linked to the initiating substrate and further additions are hindered by the 3′-hydroxyl protecting group. Methods in which a mononucleotide immobilized on a solid support is added to a free polynucleotide chain are also disclosed.
摘要:
Disclosed is a method for synthesizing polynucleotide molecules such as genes or gene segments. A primer having 5' and 3' ends is incubated with a relatively shorter template having a 5' region non-complementary to the primer, a 3' region complementary to the 3' end of the primer, and a non-reactive 3' terminus to allow the 3' region of the template to anneal to the primer. The annealed product is reacted with at least one nucleotide in the presence of a template-dependent polynucleotide polymerase to produce a primer extended at its 3' end by at least one nucleotide complementary to the 5' region of the template. The extended primer is then dissociated from the template. The extended primer is further extended by repeating this cycle for sufficient cycles, wherein the templates and enzymes may differ from cycle to cycle, to obtain the object polynucleotide. Also disclosed are template libraries and kits containing said libraries for use in conjunction with the polynucleotide synthesis method.
