a, HEK293T cells were co-transfected with relevant plasmids, cells were collected at 48 h after transfection and immunoprecipitated with anti-Flag gel (Bimake, B23101). “*” non-specific bands. b, HEK293T cells co-transfected with GFP-SUMO1 or its SUMOylation mutant and Flag-α-catenin. Cell extracts were inmmunoprecipitated with Flag gel described in a.

产品储存溶剂
Bimake Anti-Flag Affinity Gel 储存溶剂:10 mM Na3PO4, 150 mM NaCl, 50% 甘油, pH 7.4,含有0.02%(w/v)叠氮化钠。
储存条件
未开封的产品可在-20℃稳定保存2年。使用后需保存在储存溶剂(50%甘油,10 mM Na3PO4,150 mM NaCl,0.02%叠氮化钠,pH7.4)中并且禁止在不含甘油的溶剂中冻存。
操作步骤
凝胶预处理
1、轻微重悬Anti-Flag Affinity Gel使均一,迅速转移10 μL混合液(约5 μL纯胶)至新的离心管中。
2、加入500 μL TBS (50 mM Tris HCl, 150 mM NaCl, pH 7.4),轻轻混匀,5,000 rpm离心30s,弃上清,重复上述步骤3-4次。
样本的结合
3、上述的凝胶中加入50-200 μL细胞裂解液,然后室温孵育2 h或4 ℃条件下过夜。
4、5,000 rpm离心30s,将上清液转移到新的离心管中备用(上清液可用于检测Flag-tag蛋白是否存在残留)。
洗涤
5、向上述沉淀中加入500 μL PBST(NaCl 136.89 mM; KCl 2.67 mM;Na2HPO4 8.1 mM; KH2PO4 1.76 mM;0.5% Tween20),用移液器轻柔地吹打重新分散凝胶,然后上下翻转样品5 min。5000rpm离心30s,弃上清。
6、重复上述步骤两次。如遇到非特异性杂蛋白去除不干净的情况,请延长清洗时间、增加清洗次数或适当增加清洗液中去垢剂的含量。
洗脱
根据下游用途选择不同的洗脱方法,进行免疫共沉淀可直接进行7-8步;进行蛋白纯化可根据后续实验,选择多肽竞争性洗脱(9-10步)或low pH洗脱(11-12步)
变性洗脱(适用于利用Anti-Flag Affinity Gel进行免疫共沉淀实验):
7、对于直接检测目的蛋白的情况,在上述所得沉淀中加入50 μL 1×蛋白上样缓冲液,煮沸5 min,冷却至室温并离心。
8、取上清进行SDS-PAGE检测。
Poly FLAG多肽竞争性洗脱(适用于利用Anti-Flag Affinity Gel进行蛋白纯化实验):
9、将含有200 ug-1 mg/ml Poly Flag多肽(B23111)的TBS缓冲液加入步骤6的产物中,Poly FLag多肽缓冲液体积为凝胶使用量的5倍,4℃摇床孵育洗脱2 hour(为了提高洗脱效率,可延长孵育时间或重复洗脱)
10、将上述步骤得到的产物进行离心(5000rpm,30s),将包含目的蛋白的上清转移到新的EP管中。凝胶如需重复使用,需用0.1M glycine HCl(pH 3.0)进行清洗后再回收。
低pH洗脱(适用于利用Anti-Flag Affinity Gel进行蛋白纯化实验):
11、将0.1M glycine HCl(pH 3.0)洗脱液加入步骤6中的产物中,洗脱液体积为凝胶使用量的5倍,摇床孵育洗脱5min,洗脱时间不得超过20 min。
12、将上述产物进行离心(5000rpm,30s),将洗脱产物立即加入1M Tris(pH 8.0)进行中和,并调节pH直至中性。
