Abstract:
Bursa of Fabricius is a very important organ for B-eell development. We sot bursa extracts from 2-3 months old Peking Duck. A partially purified PFC-stimulating active factor has been seperated from the extracts by twice molecular sieve chromatography, Sephadex G-15 and Moselect G-10. The M. W. of the active factor is below 750 dal. The results of HPLC analysis of the factor show that its polarity is relatively strong, and it has more positive charges.The works of purifying and looking for a new assay are still going on.
