In the production process of biopharmaceutical proteins, most of target proteins were often expressed with a 6 × Histag using genetic engineering techniques, which is convenient to be purified by immobilized metal ion affinity chromatography ( IMAC). 在利用基因工程技术生产生物医药蛋白的过程中,通常在目标蛋白质尾部添加一段(His)6标签,以便于利用固定化金属离子亲和色谱(IMAC)对目标蛋白质进行分离纯化。
The algorithm combines the immune and genetic mechanism. Through the choice of vaccine and vaccination, the value of the fingerprint image and the antibody concentration are regarded as antibodies affinity function. 本方法集免疫机制和遗传机制为一体,通过对疫苗的选择和接种,将指纹图像灰度值的一致性和抗体浓度作为抗体的亲和力函数,进行遗传迭代,产生最优的分割抗体。
In recent years, the genetic algorithm-based feature selection and affinity propagation cluster have received widespread attention. 近几年来,基于遗传算法的特征选择方法以及近邻传播(AffinityPropagation,简称AP)的聚类算法受到了大家的广泛关注。
The results showed that inhibitory assay could reveal the genetic affinity to some extent. However, its inhibitory extent was influenced by subjective factor of experimenter and medium component. The inhibitory assay could only be a kind of assistant method of genetic differences identification between strains. 试验结果说明拮抗试验可一定程度地反应亲缘关系的远近,但其拮抗程度受实验者的主观因素及培养基成分的影响,只能作为菌株遗传差异鉴定的一个辅助方法。
