The present invention relates to epitopes of the epidermal growth factor receptor (EGFR) and the use thereof. The epitopes provided by the present invention are highly preserved, and located in the domain closely related to binding with an epidermal growth factor (EGF). Therefore, vaccine compositions comprising the epitopes or compositions comprising antibodies to the epitopes may efficiently block a signal transduction caused by binding of EGF and EGRF, and thus can be highly valuably used in treating various diseases such as cancer. An antibody bound to the epitopes of the present invention may efficiently inhibit binding of various EGFR ligands such as not only EGF but also TGF-a, AR, BTC, EPR and HB-EGF, with EGFR, and therefore can be used in treating various diseases resulting from an activation of EGFR caused by binding not only with EGF but also with other EGFR ligands.


A method for preparing a highly concentrated fibrinogen solution includes adding amino acid or amino acid derivatives, and/or salts to a lowly concentrated fibrinogen solution, followed by a ultra-filtration concentration. Factor XIII can be added either before or after the ultra-filtration to give a fibrin sealant component


The present invention provides an antibody that binds to the surface antigen (HBsAg) of hepatitis B virus (HBV) to neutralize the hepatitis B virus. The surface antigen-binding site of the antibody was found to play a very important role in viral replication, and when a mutation in the site occurs, viral replication is significantly inhibited, and thus at least HBV virus cannot cause a mutation in the site. In the present invention, it was confirmed by the use of patient-derived virus that the antibody of the present invention binds to either YMDD mutant hepatitis B virus, produced by conventional viral replication inhibitors, or G145R HBsAg mutants to which plasma-derived HBIG (hepatitis B immunoglobulin) does not bind. In addition, the in vivo effect of the antibody of the present invention was examined using chimpanzees which are unique animal models for hepatitis B virus. As a result, it was found that the antibody has the effect of neutralizing even wild-type hepatitis B virus in the in vivo model. Thus, it can be seen that the antibody of the present invention has the ability to bind not only to wild-type hepatitis B virus, but also mutant hepatitis B viruses having a polymerase YMDD mutant and a surface antigen G145R mutation, as well as various mutant viruses derived from patients. Thus, the antibody of the present invention can be effectively used for the prevention or treatment of infections with not only wild-type hepatitis B virus, but also mutant hepatitis B viruses.

The present invention relates to a method for diagnosing myotonic dystrophy type 1 or a method for identifying myotonic dystrophy type 1 patients by using a computer processor. According to the method of the present invention, it is possible to take suitable measures related to symptoms, which will occur later, by classifying a genetic carrier and first to third risk groups according to the repetition number of the CTF sequence of 3-noncoding region of the DMPK gene. Particularly, the method of the present invention numerically provides a genetic carrier or the approximate prevalence of a disease with respect to an unborn baby, thereby allowing the risk of disorders to be accurately understood.
