Abstract

The influence of the cattle cord blood low-molecular fraction (below 5 kDa) on the functional activity of leukocytes after cryopreservation was studied. The stimulating effects of the fraction (0.15 mg/ml) on digesting and engulfing activities of frozenthawed neutrophils were observed. It was established that the usage of dimethyl acetamide (5%) as a cryoprotectant allowed preserving up to 80% of viable leukocytes.
