We have reported that an inhibitor of interleukin-3 (NIL-3) is produced from murine bone marrow cells in response to excess stimulation of interleukin-3. In this report, we attempted the purification of the NIL-3 activity from bone marrow culture supernatant in the presence of interleukin-3. The purified NIL-3 activity was a protein with relative molecular weight of 54.5 kDa (SDS-PAGE), which inhibited the growth of IL-3 dependent DA-1 cell growth in a dose dependent manner. The N-terminal amino acid sequence of purified NIL-3 activity was determined to be homologous to beta-2 glycoprotein I (apolipoprotein H: APO-H). The gene expression of APO-H was detected by nested-PCR in STIL-3 C5-CM stimulated total bone marrow cells and STIL-3 C5-CM stimulated bone marrow fraction 2 (Fr. 2) which has been reported as a hematopoietic stem cell rich fraction. These observations indicate the possibility that the APO-H is the NIL-3 which was produced from bone marrow cells in response to excess IL-3 stimuli.
