AGScientific,Inc.成立于1997年,专注于创新生化制剂以及用于诊断测试开发的定制原材料,以推进临床前研究药物开发。产品涉及抗生素,生物洗涤剂,缓冲液,诊断,酶,医疗设备试剂,蛋白酶K,还原剂,RNaseA等。
CHAPS是一种两性离子洗涤剂,广泛应用于蛋白质纯化过程。作为这类洗涤剂的一部分,CHAPS含有一个正电荷和一个负电荷,但没有一个净的总电荷。CHAPS的生物膜亲和力相对较低,但在特定的浓度范围内可以有效地诱导溶血和蛋白溶解。CHAPS被归类为一种临界胶束浓度为6-10mM的非变性表面活性剂。
CHAPS的应用:在实验室中,CHAPS和其他两性离子洗涤剂可用于在分离蛋白之前诱导细胞裂解。它也可以用作二维凝胶电泳过程中的缓冲液,在某些情况下,它比SDS等阴离子洗涤剂更受欢迎。在蛋白质分析之前,可以通过透析从溶液中去除CHAPS。另一种技术利用专门的树脂和旋转柱也可以用来有效地去除皲裂用于监测化学反应或蛋白质结合的紫外/可见光谱学•用于离子交换色谱和等电色谱•用于细胞的膜渗透•以酶特性作为变性缓冲液的成分
嘌呤霉素盐酸盐是从阿氏链霉菌中分离得到的氨基糖苷类抗生素。嘌呤霉素是一种蛋白质合成抑制剂,它将自己整合到一个正在生长的多肽链中,导致其提前终止。嘌呤霉素的主要应用是作为基因选择抗生素,在CRISPR/Cas9基因编辑中发挥重要作用。这种以盐酸盐形式存在的嘌呤霉素试剂具有抗肿瘤、抗锥虫和抗菌的特性。重要的是要将嘌呤霉素盐酸盐储存在一个密闭的容器中,并置于通风干燥的地方。
盐酸贝斯他汀是氨基肽酶,氨基肽酶B,氨基肽酶M(CD13),和链霉菌来源的亮氨酸氨基肽酶(LAP3)的一种金属蛋白酶抑制剂。这些蛋白的抑制作用是由于肿瘤细胞的凋亡诱导。Bestatin在抗癌化疗、免疫调节、镇痛等方面表现出良好的疗效。
蛋白酶K(又称内肽酶K)是一种从真菌Tritirachiumalbumlimber培养滤液中分离出的胞外内肽酶。这种独特的真菌可以降解角蛋白(因此蛋白酶“K”),并可以利用其副产品作为碳和氮的唯一来源来生长。该酶在较宽的温度和pH范围内是稳定的,在55-65℃和pH8.0时是最佳活性。它在高盐浓度下也很稳定,在强洗涤剂如SDS的存在下也很活跃。其分子量为28.5kDa,对其多肽靶点的特异性较低。
AG蛋白酶K应用于下一代测序(NGS)和微阵列技术•核酸纯化,当从酵母、细菌、哺乳动物细胞和植物细胞裂解物中提取DNA和RNA时,通过灭活核酸酶来纯化核酸•提高PCR产物的克隆效率•使用加速器质谱法对DNA加合物水平进行定量的样品准备•核糖核酸酶保护试验中鸡尾酒酶的失活•添加到提取程序,以优化微阵列研究的原始乳腺肿瘤的RNA产量应用于蛋白质•检测具有独特抗蛋白降解能力的牛海绵状脑病蛋白。•组织消解作为另一种样品制备方法,用于液相色谱-串联质谱定量分析•特异性修饰细胞表面蛋白,分析膜结构进行蛋白定位•生成用于功能研究表征的蛋白片段

MaggotsFasterThanScalpelinWoundDebridement

1. 姜黄素是一个典型的HAT抑制剂。
2. 针对P300: 在大约10年前,Cole和他的同事设计出了一种p300/CBP抑制剂,发表在nature杂志上。
希望能帮到你,望采纳!
天然产物,大多都有颜色,
存在干扰,多数情况下需要做样品的阴性对照,
尽量能用荧光的方法,
之前我们做过,将两个试剂盒的方法合并后,做的,
效果还可以
支原体培养则是取样后在培养基上培养,看有多少支原体菌落会长出,是比较直观和可信的结果。
总体来讲,这两种检查手段可信度都较高,结合一起,不仅可以可靠的知道有无解脲支原体感染,还能知道感染是否严重。
