摘要
用差示扫描量热技术(DSC)测定了从黄粉(Tenebrio molitor)幼虫体内提取的抗冻蛋白(AFP)的活性,结果表明AFP活性随其浓度的增加及初始冰晶量的减少而增大,这与AFP对冰晶的吸附-抑制机制相一致。
The activity of antifreeze protein (AFP) in Tenebrio molitor is analyzed by differential scanning calorimetry (DSC). It is shown that the antifreeze activity of AFP increases with decrease of initial ice crystal, and increase of concentration of AFP. These results are accordant with the absorption-inhibition mechanism of AFP.
