In this study, a mouse monoclonal antibody (mAb) against gp41(584-618), the immunodominant epitope protein, was generated. For this purpose, BALB/c mice were immunized with double branched multiple antigenic peptides derived from the HIV-1 gp41(584-618) sequence, and antibody-secreting hybridoma were produced by fusion of mice splenocytes with SP2/0 myeloma cells. One clone producing an antigen specific mAb, termed KI-41(isotype IgG1) was identified, whose specific reactivity against gp41(584-618) could be confirmed by ELISA and Western blot analysis. Epitope mapping revealed the recognition site of the mAb KI-41 to be located around the sequence RILAVERYLKDQQLLG, which comprises the N-terminal region within the immunized gp41(584-618) peptied. Since this mAb recognizes this specific epitope within the HIV-1 gp41 without any cross-reactivity to other immunodominant regions in the HIV-2 gp35, KI-41 will provide some alternative possibilities in further applications such as the development of indirect or competitive ELISA for specific antibody detection in HIV-1 infection or for other basic researches regarding the role and function of HIV-1 gp41.
The purpose of this study is to develop a patient care standard which is the basis of unit based quality assurance. The subjects were 570 nurses of 6 hospitals is Seoul. Patient Care Standards were developed from 3 times of clinical Nurses Association's workshop & the joint meeting of Clinical Nurses Association & the Korean Nurses Academic Socity of Nursing Administration. Respondents were instructed to rate of the 2 types of 5 - point Likert type questionnaire(one is the level of perceived importance, the other is the level of actual performance) Findings of this study were as follows 1. As a results of reliability analysis, each questionnaire ranged from
