摘要:
Disclosed is an IgG Fc fragment useful as a drug carrier. Also, the present invention discloses a recombinant vector expressing the IgG Fc fragment, a transformant transformed with the recombinant vector, and a method of preparing an IgG Fc fragment, comprising culturing the transformant. When conjugated to a certain drug, the IgG Fc fragment improves the in vivo duration of action of the drug and minimizes the in vivo activity reduction of the drug.
摘要:
Disclosed are a recombinant expression vector comprising a nucleotide sequence encoding an E. coli-derived signal sequence and a nucleotide sequence encoding an immunoglobulin constant region, and a transformant transformed with the expression vector. Also, disclosed is a method of mass-producing an immunoglobulin constant region by culturing the transformant and expressing the immunoglobulin constant region in a water-soluble form.

The present invention relates to a photosensitive resin composition, particularly to a photosensitive resin composition for forming an interlayer organic insulating film for TFT-LCD, comprising 0.01 to 20 wt % of UV stabilizer or radical scavenger. The photosensitive resin composition of the present invention can be used for forming an interlayer organic insulating film for TFT-LCD to improve active unfilled area upon over exposure in liquid crystal photo-alignment process, can easily control resolution of pattern, and is particularly suitable for forming a planarization layer of an interlayer organic insulating film.

摘要:
A recombinant expression vector capable of expressing and secreting an antibody fragment fused with E. coli thermostable enterotoxin signal sequence derivative or E. coli outer membrane protein A (Omp A) signal sequence in the form of a soluble heterozygote protein is used to mass-produce the antibody fragment by culturing a microorganism transformed with the expression vector in a medium and collecting the antibody fragment secreted from the transformed microorganism into the medium.
摘要:
The present invention relates to a long-acting interferon beta formulation having improved in vivo duration and stability, comprising an interferon beta conjugate that is prepared by covalently linking interferon beta with an immunoglobulin Fc region via a non-peptidyl polymer, and a preparation method thereof. The long-acting interferon beta formulation of the present invention maintains in vivo activity of interferon beta at a relatively high level and remarkably increases the serum half-life thereof, thereby being used for various diseases, for which interferon is efficacious.

摘要:
Disclosed is a method for the mass production of a monomeric or dimeric immunoglobulin Fc region, free of initial methionine residues, using a recombinant expression vector comprising a nucleotide sequence coding for a recombinant immunoglobulin Fc region comprising an immunoglobulin Fc region linked at the N-terminus thereof to an immunoglobulin Fc region via a peptide bond.
