A total of 22 pairs of bear serum (winter and summer) were collected during the indicated years. Equal volumes of serum were used to obtain four different mixes (M1W to M4W) of winter bear serum (WBS) and four paired mixes (M1S to M4S) of summer bear serum (SBS). All experiments presented in this study were performed with each of the mixes as replicates. Averages are given as mean ± SEM.
