Compositions and biological activities of the extracted low molecular fractions have been analysed comparatively. The influence of low-temperature storage and lyophilization on the biological activity of the cattle cord blood fraction (below 5 kDa) has been studied. The data obtained give evidence that the cattle cord blood fraction (below 5 kDa) has the most conspicuous biological activity. A high biological activity remains in the low molecular fraction from blood of young animals, but it disappears in the fraction from adult blood, which correlates with changes in the fraction composition. Lyophilization has no effect on the biological activity of the cattle cord blood fraction (below 5 kDa). The storage of the lyophilized fraction is more reliable than the storage of this fraction in the form of a frozen solution at -80 C.
