是的,金标准是要破除的。
期待早日有更多同类的试剂盒,出来和CYGNUS竞争,间接促进它提供更好的服务。
Our original Pichia pastoris HCP ELISA Kit (F140) has broad reactivity to peptide epitopes and a small population of antibodies that recognize Pichia glycosylation epitopes. In cases where the recombinant protein product is also glycosylated, there is potential for some cross-reactivity that can result in either an over-estimation of true HCP or indeterminate HCP concentrations, due to the lack of sample dilution linearity. The antibody used in this kit is the same polyclonal antibody that is used in the original kit, except that it has been subjected to an additional affinity absorption step to remove antibodies to glycosylation epitopes and is more specific than the first-generation Pichia pastoris Kit (F140).
我们的原始毕赤酵母HCP ELISA试剂盒 (F140)对肽表位和一小部分识别毕赤酵母糖基化表位的抗体具有广泛的反应性。在重组蛋白产物也被糖基化的情况下,由于缺乏样品稀释线性,可能会导致对真实HCP的高估或不确定的HCP浓度。本试剂盒中使用的抗体与原试剂盒中使用的多克隆抗体相同,只是它经过了额外的亲和吸收步骤以去除糖基化表位的抗体,并且比第一代毕赤酵母试剂盒更具特异性(F140)。
官网只撂下这么一段话,解释第二代(F640)和第一代(F140)的区别,哎... |
