The objective of this study was to determine whether α-adrenergic receptors are involved in the contractile activity of neuropeptide Y (NPY) in the porcine isolated ovarian artery collected from immat...
Effect of pH on the Conformation and Biological Activity of Clostridium septicum Alpha-toxin, a Pore-forming Hemolysin
Clostridium septicum alpha-toxin hemolytic activity lethality pH
2009/1/19
The effects of pH on the pore-forming Clostridium septicum alpha-toxin that causes myonecrosis was assessed at pH 5.0, 7.0 and 9.0 by measuring circular dichroism and its biological activity. Incubat...
干扰素（IFN）是一种具有广谱抗病毒、抗肿瘤以及免疫调节等活性的细胞因子。该研究通过PCR从AA肉鸡基因组DNA中克隆了IFN-（ChIFN-）基因，测序分析，并将该基因与表达载体pQE30相连，构建重组表达质粒pQE30/ChIFN-，以IPTG诱导在M15中进行表达。测序结果表明ChIFN-的开放阅读框（ORF）是由486个核苷酸编码的，成熟蛋白为162个氨基酸，有4个糖基化位点，推测分子量为...
