소 설사병 바이러스 구조단백에 대한 단크론항체를 작성하여 혈청중화시험, 전기영동, 면역침전반응을 이용하여 분석하였던 바 다음의 결과를 얻었다. 중화능력이 있는 항체의 경우 56K내지 54K의 구조단백에 대응하였다. 그외 중화력을 나타내지 않는 항체는 45K와 36K의 바이러스 항원과 대응하였다. 순수정제된 바이러스의 전기영동 분석결과 12종 이상의 바이러스 단백성분이 구조단백질로서 검출되었으며 중화능력을 나타내는 항체를 이용한 면역침전 결과는 이들의 존재를 뒷받침하였다. 중화단백성분의 세포내 전구물질의 검출은 불가능하였으나 방사선동위원소 부착즉시 세포배지에서 바이러스의 존재를 확인할 수 있었다. Staphylococcus aureus $V_8$효소를 이용한 항원의 부분소화 분석결과 45K와 36K의 바이러스 항원은 서로 상관이 있는 것으로서 입증되었다.

The three yolk polypeptides have been isolated and partially characterized. Their molecular weights of YPI, YP2, and YP3 were 48, 000, 47, 000, and 46, 000, respectivelv, as judged by SDS-polyacrvlamide gel electrophoresis. They have different digestion products upon in situ peptide mapping by limited proteolysis. Two-dimensional gel electrophoresis showed that their isoelectric points were heterogeneous from 5.92 to 6.54. And thew showed three different antigen-antibody reactions when each polvpeptides is reacted with antisera made to a mixture of all of three. These data reported here indicate that the yolk proteins are consisted of distinctive polypeptides in Drosophlla sp. (robusta species group).

An attempt was made to link rice embryo proteins to DNA sequences and to understand their functions. One hundred of the 700 spots detected on the embryo 2-DE gels were microsequenced. Of these, 28% of the embryo proteins were matched to DNA sequences with known functions, but 72% of the proteins were unknown in functions as previously reported (Woo et al. 2002). In addition, twenty-four protein spots with 100% of homology and nine with over 80% were matched to ESTs (expressed sequence tags) after expanding the amino acid sequences of the protein spots by Database searches using the available rice EST databases at the NCBI (http://www/ncbi.nlm.nih.gov/) and DDBJ (http://www.ddbj.nig.ac.jp/). The chromosomal location of some proteins were also obtained from the rice genetic map provided by Japanese Rice Genome Research Program (http://rgp.dna.affrc.go.jp). The DNA sequence databases including EST have been reported for rice (Oryza sativa L.) now provides whole or partial gene sequence, and recent advances in protein characterization allow the linking proteins to DNA sequences in the functional analysis. This work shows that proteome analysis could be a useful tool strategy to link sequence information and to functional genomics.
