一般描述
产品来源：从CHO细胞中表达的人成纤维细胞mRNA中获得的cDNA。
重组人干扰素β 1a (Hu-IFNβ 1a)。 分子量约为 23 kDa。
联系
替代：IF008
外形
50 mM NaOAc，pH 5.5，含有 0.1% BSA中的冷冻液体。
储存及稳定性
接收后，该产品应在-70°℃或更低温度下保存，以保留全部活性。
用冷水孵育解冻产品瓶，直到刚解冻。解冻的IFNβ应
以工作等分试样保存于-70°C中，可保存长达六个月。避免多次冻融循环。
再冻结应在干冰或干冰/酒精浴中进行。
产品的进一步稀释应在含有蛋白质的缓冲液中进行，例如 0.1% 牛血清白蛋白 (BSA)。

分析说明
比活度：通过检测病毒诱导的细胞病变的抑制作用来确定。在该干扰素抗病毒试验中，大约1单位/ml的干扰素是产生50%细胞病变效应所必需的量。这些单位是根据美国国立卫生研究院提供的人干扰素β（Hu-IFNβ）国际参考标准确定的。使用水泡性口炎病毒 (VSV) 测量 VERO 细胞的活性单位。

Viral infection of the heart is a common but underappreciated cause of heart failure. Viruses can cause direct cardiac damage by lysing infected cardiomyocytes. Inflammatory immune responses that limit viral replication can also indirectly cause damage during infection, making regulatory

Genetic knock-in using homology-directed repair is an inefficient process, requiring the selection of few modified cells and hindering its application to primary cells. Here, we describe Homology independent gene Tagging (HiTag), a method to tag a protein of interest by

The mechanism of tumor-selective replication of oncolytic measles virus (MV) is poorly understood. Using a stepwise model of cellular transformation, in which oncogenic hits were additively expressed in human bone marrow-derived mesenchymal stromal cells, we show that MV-induced oncolysis increased
