Thermo Scientific Pierce HA 标签 IP/Co-IP 试剂盒提供使用 HA 标签诱饵蛋白进行免疫沉淀 (IP) 或免疫共沉淀 (Co-IP) 反应所需的亲和树脂、阳性对照品和其他试剂。该试剂盒以共价固定了高特异性抗 HA 抗体的交联微珠状琼脂糖为基础。即用型亲和树脂以及所含缓冲液、微量离心柱、阳性对照品和易于遵循的说明构成了足以进行 25 次 IP 或 Co-IP 测定的全套试剂。在培养出含有标记融合蛋白质的样本后,在琼脂糖微珠上捕捉到含有HA标记诱饵蛋白质的相互作用复合物。简单洗涤步骤后,在提供的洗脱缓冲液或 SDS-PAGE 上样缓冲液中易于从树脂中洗脱特异性蛋白相互作用复合物,以进行后续分析。源于人流感病毒 HA 蛋白的血凝素 (HA) 肽 (YPYDVPDYA) 是几种用于重组蛋白表达的融合蛋白标签之一。利用特异性、高亲和力固定化抗体,HA 标签融合蛋白可从细菌和哺乳动物细胞裂解物以及 Pierce 人体外翻译反应液中快速纯化。对于免疫共沉淀反应,简单的洗涤步骤可在提供的洗脱缓冲液或 SDS-PAGE 上样缓冲液中富集和洗脱特异性蛋白相互作用复合物,以便进行后续分析。 |

Immunoprecipitation of HA-tagged protein (GST-PI3K-SH2-HA) from E. coli lysateCoomassie Stained gel. Lane 1: MW marker, Lane 2: 15µL of 0.25mg/mL of positive control lysate, Lane 3: 15µL of Flow-through, Lane 4: 15µL of Glycine, pH 2.8 elution fraction. Co-immunoprecipitation of active E2F1:HA-tagged pRb complexHA-tagged pRb was expressed using a Pierce Human in vitro Expression System. 50µL of the translation reaction was diluted to 200µL in TBS and added to 15µL of agarose resin and incubated for 1 hour at 4°C as a non-specific pre-clearing step. The cleared translation reaction was added to 50µL of anti-HA resin and incubated for 3 hours at 4°C with end-over-end rocking. The resin was washed with 3 x 500µL of TBS-T. HA-pRb:E2F1 complex was eluted with the addition of 30µL of 2X non-reducing sample buffer. In vitro translation reactions without and with HA-pRb DNA (lanes 1 and 3, respectively) and anti-HA agarose elution fractions from each (lanes 2 and 4, respectively) were probed with rabbit anti-E2F1 (Part No. PA5-17549) and mouse anti-HA (Part No. 26183) and detected with Thermo Scientific SuperSignal West Dura Extended Duration Substrate (Part No. 34075). |
