摘要:
The present invention relates to a fusion protein or peptide, the in vivo half-life of which is increased by maintaining in vivo sustained release, and to a method for increasing in vivo half-life using same. A fusion protein or peptide according to the present invention has excellent in vivo stability by binding a physiologically active protein or physiologically active peptide to an alpha-1 antitrypsin or alpha-1 antitrypsin mutant with one or more amino acids mutated to maintain the in vivo sustained release and to significantly increase the half-life thereof in blood (T1/2) compared to an inherent physiologically active protein or physiologically active peptide. Thus, a fusion protein or peptide according to the present invention can be useful in developing a sustained-release preparation of a protein or peptide drug.

摘要:
Disclosed are an immunoassay of Plasmodium falciparum for determining the presence/absence of a specific and/or antibody thereof via label in conjugates bound to the specific antigen and/or antibody present in a sample, comprising immobilizing the specific antigen and antibody of Plasmodium falciparum on a solid phase, adding a sample obtained from a subject of interest to the solid phase so as to induce specific antibody-antigen reaction, adding a conjugate of the antigen and a label and a conjugate of the antibody and a label, separately prepared, so as to induce binding of at least one of the conjugates; and an assay device comprising the above-mentioned solid phase and conjugates.The present invention can effect specific detection of antigens and/or antibodies in patients with manifested malaria-symptoms as well as malaria carriers and can also be efficiently employed in samples at the early stage of malaria infection that is difficult to detect via conventional arts. Further, due to the capacity to utilize sera and blood plasma rather than whole blood, the present invention is well suited to large-scale examination such as blood screening.
