Phytohemagglutinin （PHA）, concanavalin A （ConA）and lipopolysaccharide （LPS） were used as lymphocyte proliferation mitogen, respectively. According to L 25 （5^6） five-factor five-level orthogonal experimental design, the conditions for sturgeons proliferation response of peripheral blood lymphocytes were optimized using enhanced cell counting Kit-8 （enhanced CCK-8 or WST-8）. Five factors were selected to explore the optimal response conditions, including culture time, culture temperature, cell concentration, fetal bovine serum （FBS） concentration, and mitogen concentration. The results showed that 70% Percoll （1.092 g/ml） used as the sturgeon lymphocyte separation solution had the best separating effect. The optimal proliferation conditions were as follows： 3.625×10 6 initial cells, 20 μg/ml PHA or 50 μg/ml ConA or 10 μg/ml LPS as mitogen, 10%-20% FBS, the temperature at 20-25 ℃, and the culture time of 2 d.展开更多
