复溶: Reconstitute in sterile water for a stock solution.A copy of datasheet will be provided with the products, please refer to it for details.
分子别名: Annexin A6,67 kDa calelectrin,Annexin VI,Annexin-6,Calphobindin-II,CPB-II,Chromobindin-20,Lipocortin VI,Protein III,p68,p70.
背景介绍: Annexin A6, also known as ANXA6 or ANXAⅥ, belongs to a family of Ca2+-dependent membrane and phospholipid binding proteins. Members of this family have been implicated in membrane-related events along exocytotic and endocytotic pathways. Annexin 6 is phosphorylated in vivo associated with cell growth. Annexin 6 was not phosphorylated in quiescent cells, but was phosphorylated on serine and to a lesser extent threonine, several hours following cell stimulation. Experiment has revealed the presence of annexin A6 on the cell surface of variety cells as putative receptors and / or binding proteins for chondroitin sulfate proteoglycans, helping cells to bind with this extracellular matrix glycosaminoglycan chondroitin sulfate which is related to the cell-substratum adhesion. A post-tranlational modification other than direct protein phosphorylation may influence the activity of annexin6 and provide evidence linking cell growth with regulation of annexin 6 function.
表达载体在基因工程有以下几种元件:

(5)宿主体内自主复制的序列。
重组蛋白质的诱导表达:
1. 挑取转化有质粒的单菌落, 接种于 3ml 选择性 LB 液体培养基中, 37 oC,250 rpm/min 振摇培养过夜。
2. 次日将培养过夜的菌液 500 μl 再接种于 10ml(1:20)选择性 LB 液体培养基 中, 37 oC,250 rpm/min 振摇培养至光密度(OD600=0.6)时,取 1 ml 样本作 为诱导前标本, 10000g 离心 1min 收集菌体沉淀,-20 oC 冻存备用。
3. 加入 1 mol/L IPTG 于菌液中,使 IPTG 终浓度为 1 mM ,37 oC ,250 rpm/min 振摇培养 4 ~ 5 小时。取 1 ml 样本作为诱导后标本,同上法收集菌体沉淀, -20 oC 冻存备用。
4. 将诱导前后菌体沉淀用 20 ~ 40 μl PBS(pH= 8.0)重悬, 加入等体积的 2×SDS 上样缓冲液, 煮沸加热 5min,SDS 聚凝胶(SDS-PAGE)电泳分离 , 考马斯亮蓝染色 3 小时后,脱色观察结果。
5. 选取诱导成功的细菌克隆,扩大诱导规模,收集菌体沉淀,于- 20 oC 保存,准备做下一步分析及纯化。

重组蛋白质的可溶性鉴定:
1. 将按上法诱导培养后收集的菌体重悬于裂解液 1 (Lysis buffer under native conditions )中,然后在-80 oC 低温冰箱中放置 10 min。
2. 冰中解冻。
3. 在冰浴上用超声破碎仪破菌 6 次, 每次 10 sec,间歇 10 sec,电压 200-300 V。
4. 10000g,4oC,离心 20min,取上清(为溶液 A), - 20 oC 保存; 另将沉淀用 同样裂解液 1 溶解(为溶液 B),同样 -20 oC 保存,供后继分析使用。
5. 将上述 A、B 溶液和诱导前后的细菌进行 SDS-PAGE 电泳, 考马斯亮蓝染色, 比较分析重组蛋白质的溶解性。如果诱导表达的蛋白质位于 A 溶液中, 则为可溶性蛋白;如果是在 B 溶液中,则为非可溶蛋白。
重组蛋白质的分离纯化:
1. 将菌体沉淀溶于适量裂解液 2(Lysis buffer under denaturing conditions )中,室温下搅拌和吹打沉淀,避免泡沫生成。

4. 将适量上清液上样到 Ni-NTAAgarose 柱子中, 并用 lysis buffer 冲洗至 A280 值低于 0.01。
5. 分别用 5 ~ 10 倍柱体积的清洗液 1 和清洗液 2(Washbuffer 1 and 2)清洗柱 子,直至 A280 值低于 0.01。
6. 用洗脱液(Elution buffer)洗脱重组蛋白质, 在 A280 值监测下,收集出现峰 线后含有重组蛋白的所有洗脱液。
