牙鲆HRI多克隆抗体的制备及病毒诱导的组织表达分析

血红素调节的eIF2α激酶HRI是一种丝氨酸/苏氨酸蛋白激酶,在血红素缺乏和热休克等胁迫存在时,通过磷酸化底物eIF2α调控真核细胞的蛋白合成。牙鲆PoHRI是在鱼类鉴定的第一个HRI基因。PCR克隆编码PoHRI蛋白1-200氨基酸的cDNA片段,定向插入pET32a构建表达载体。IPTG诱导,随后利用Ni2+-NTA亲和层析柱纯化,成功获得预期大小的融合蛋白。将纯化的融合蛋白免疫小鼠获得抗PoHRI多克隆抗体,抗体中和实验进一步证实了抗PoHRI多克隆抗体对PoHRI蛋白的特异性识别。在健康的牙鲆组织

Haptic Sensation and Instrumental Transgression

Anyone who has ever played a musical instrument will certify the development of a particular type of relationship between the instrument and the performer. This relationship goes beyond a convenient coupling that is optimized for sound production. Every musical instrument defines ways in which to be touched, felt, activated. Music performance is dependent on bodily involvement that goes beyond the auditory and the sense of hearing. This article investigates the role of haptic sensation in the context of the performer-instrument relationship and draws on the writings of Georges Bataille to illuminate a discussion of the erotic in performance.
