Recombinant Rabbit Anti-PEG Monoclonal Antibody (clone 58H11) was determined by SDS-PAGE under reducing (R) and non-reducing (NR) conditions.
A microtiter plate was coated overnight with Recombinant Rabbit Anti-PEG Monoclonal Antibody (clone 58H11). After washing and blocking with PBST + 5% skim milk, increasing concentrations of biotinylated PEG was added. Horseradish Peroxidase conjμgated Neutravidin was used for final detection.

PEG (Polyethylene glycol) is a polyether compound with many applications from industrial manufacturing to medicine. PEGylation is a technology that covalently couples non-toxic, hydrophilic polyethylene glycol (PEG) to the drug. It is an FDA-approved method for the delivery of protein drugs. PEG modification can reduce the drug immunogenicity and antigenicity. PEGylated drug decelerates renal excretion, improves stability towards proteolysis and increases its half-life in blood. Accurate and sensitive quantification of PEG conjugates is important for PEG conjugated product development and pharmaceutical study. Polyethylene glycol (PEG) antibody is a useful tool for the detection of PEGylated molecules.
首先，一般抗体不推荐客户回收利用，抗体使用之后缓冲体系已经发生改变，不同客户在回收抗体的保存条件上也会有差异，所以抗体回收使用效果无法保证。另外，ABclonal公司也做过一批抗体回收验证测试，测试结果显示不同抗体可回收次数不同，一般效价越高的抗体，可重复使用的次数越多，客户可根据实验情况来确定。
注：我们将孵育完毕后剩余的抗体回收到离心管中置于4℃保存，效价高的抗体可至少保存1周，至少重复利用3次。
武汉爱博泰克生物（ABclonal）科技有限公司是国产品牌，她成立于2011年，公司依托ABclonal美国波士顿抗体与蛋白研发中心、中国光谷生物城(武汉)抗体生产基地以及上海张江分子酶研发中心，凝聚了十余位来自哈佛大学、麻省理工、复旦大学、上海交大、中科院生化细胞所和武汉大学的全球知名分子和免疫学方面博士，组成我们的科学家团队，通过聚焦抗体与酶核心技术，致力于打破国际技术的垄断，将公司打造成为科研工具和诊断原料的国内领导品牌，乃至弯道超越国际巨头。 我们拥有包括兔多克隆抗体、小鼠单克隆抗体、兔单克隆抗体的生产研发平台，同时也有包括WB,IHC,IF,IP,CHIP在内的检测平台，我们对每一支自产的抗体进行了严格的检测。当然，我们部分直销地区也可以帮客户代购进口品牌的产品。同时也有抗体定制服务。ABclonal抗体优势：1，严自检，保质量；2产品多，指标全；3，价格低，货期短。注：ABclonal抗体价格体系详情见附件
ABclonal抗体成分在平时工作当中，常会有客户咨询我们的抗体用的什么buffer进行保存，一般来说，我们的buffer的成分是：PBS含0.03%的proclin300、0.05%牛血清白蛋白、50%甘油；也有一些是PBS含0.03%的proclin300，50%甘油。防腐剂 Proclin 300活性成分主要是2-甲基-4-异噻唑啉-3-酮（MCI）和5-氯-2-甲基-4-异噻唑啉-3-酮（CMCI）。ProClin生物灭活剂能够迅速穿透细胞膜，抑制对细胞呼吸至关重要的特定酶，因此一接触微生物有机体就会立即抑制细胞活性。ProClin的多个特定毒性位点可以防止微生物产生高水平的耐药性。
