面筋蛋白外啡肽B5对传染性支气管炎灭活疫苗免疫效果的影响
面筋蛋白 外啡肽B5 功能性饲料添加剂 动物疫苗佐剂
2016/3/30
麦谷蛋白源外啡肽B5来源于麦谷蛋白酶解产物，具有阿片样活性。作者通过进一步优化化学合成工艺制备外啡肽B5，并将其添加到传染性支气管炎病毒（IBV）H120株灭活疫苗中，免疫后21 d（35日龄） 采用IBV M41株病毒液进行点眼、滴鼻攻毒。通过测定免疫仔鸡的生产性能、淋巴细胞增殖水平、血清抗体水平、临床症状及组织病理学变化等指标，评价外啡肽B5的应用效果。结果显示，经过化学合成工艺优化后获得了高...
旨在探讨bbu-miR-103-1在水牛泌乳期和非泌乳期的差异表达模式，并预测其靶向调控基因及功能。本研究应用qRT-PCR检测bbu-miR-103-1，在水牛泌乳期和非泌乳期的差异表达。构建bbu-miR-103-1前体表达质粒LpEZX-pre-miR-103-1,并在293T细胞中包装高滴度的慢病毒颗粒，用于感染水牛乳腺上皮细胞实现过表达bbu-miR-103-1，同时应用化学合成的bbu...
