Recombinant Mouse ICAM-1/CD54 Protein
IdeS Protease全称免疫球蛋白G降解酶,酶活(Enzymeactivity)40U/μL酶活定义(UnitDefinition)在37℃条件下,反应30min,剪切>95%的1μg重组单克隆IgG所需要的酶量定义为一个活性单位。储存条件-25~-15℃保存,有效期1年。使用方法1.在消化液中加入适量IgG(加至5mg);2.在IgG样本中加入IdeS蛋白酶(每1μgIgG加入1个单位的IdeS);3.将样品置于37℃孵育30-60min。IdeS蛋白酶在中性pH或接近中性pH的缓冲中活性强。推荐反应缓冲是50mM磷酸钠,150mMNaCl(pH6.6),多数常见的生物缓冲也适用,比如Tris或PBS;注意:不在此pH范围(例如乙酸盐缓冲液)的缓冲也可能适用,但是孵育时间或酶量需要根据实际情况进行优化。注意事项1.IdeS不能识别切割小鼠IgG1/IgG2b,大鼠、猪、牛和山羊IgG,对小鼠IgG2a和IgG3具有中等酶切活性,酶切小鼠IgG2a和IgG3建议增加IdeS的用量(推荐用量为正常用量的5-10倍)。2.IdeS不能切割非IgG亚型的单抗分子,包括IgA、IgM、IgD和IgE。然而,在肝脏中,IL-28A诱导的Th1细胞因子反应有助于T细胞介导的肝炎的炎症。Recombinant Mouse ICAM-1/CD54 Protein,His Tag

Enterokinase,Recombinant,Expressed in E.coli大肠杆菌表达重组肠激酶(不带标签)注意事项1.本产品所讲述的缓冲体系需要自行配置。2.不建议37℃条件下酶切,可能会有非特异性酶切出现。3.在>200mM咪唑,或>200mMNaCl,或>5%甘油,酶切会受到影响。如果样品溶液中含有上述成分的一种或多种,为获得理想的酶切结果,请先将样品透析到25mMTris-HCl8.0缓冲液中,然后再进行酶切实验;若不方便透析,可将样品稀释到咪唑含量在100mM以下,NaCl浓度在50mM以下,甘油浓度小于5%以下进行酶切,酶的用量与蛋白比例不变;若干扰因素很多,且不便去除,需要适当增加酶量或延长酶切时间,有助于得到理想的酶切效果。4.磷酸盐对Enterokinase有很强的抑制作用,痕量的磷酸盐都会严重影响Enterokinase的活性,因此在酶切体系内不能存在磷酸盐。5.本品是具有高酶活力重组肠激酶,切割蛋白使用量少,可不考虑除去。后续如需去除重组肠激酶,可用阴离子交换树脂(如DEAE-FF)对其进行洗脱。推荐洗脱条件如下:平衡缓冲液:25mMTris-HClpH8.0洗脱缓冲液:25mMTris-HClpH8.0,含100mMNaCl6.蛋白酶切效果不好,可适当增加酶量,或适当延长酶切时间。LAG-1与MIP-1β(ACT II同种型)相同,Lag-1趋化吸引力单核细胞,并表现出活性作为HIV抑制因子。Recombinant Biotinylated Human BDCA-2 Protein,His-Avi Tag
