DiSulfo - Cy5酰肼是一種帶有酰肼基的遠紅染料。該染料可以用作極性示蹤劑或用醛或酮基團標記生物分子(例如用高碘酸鹽過氧化后的碳水化合物分子)。實例是受到氧化應激的蛋白質和具有醛部分的寡核苷酸。
DiSulfo - Cy5酰肼替代羰基反應性Alexa Fluor 647,DyLight 650和CF™647酰肼染料。

提供材料
包裝,每個包含干染料標簽1毫克的抗體。綴合緩沖液:磷酸鹽緩沖液pH 7.0
注意:
1.所有溶劑和緩沖液應脫氣本協議是為制備二磺基 - Cy5標記的IgG抗體而設計的。它被設計為標記1毫克。這假定平均蛋白質分子量為155K道爾頓。
1.將抗體溶解在偶聯緩沖液(10mg / ml)中。將1mg要標記的抗體(0.1ml)置于0.5ml微量離心管中,并用氮氣沖洗。
2.將150μl高碘酸鈉溶液(0.1 M)加入抗體中,密封并在環境溫度下無光條件下充分混合30-45分鐘。
3.當氧化反應正在孵育時,將凝膠過濾柱平衡到偶聯緩沖液中。將高碘酸鹽反應物置于柱上:收集并合并含有抗體的級分
1.將二磺基-Cy5酰肼溶解在偶聯緩沖液中,得到0.02M溶液。
2.將等體積的抗體與二磺基 - Cy5酰肼溶液混合并在環境溫度下輕輕混合3小時或在4℃下過夜。
3.使用已經用PBS預處理的10ml凝膠過濾柱來純化產物。用PBS洗脫產品。
4.分離個有色級分,并從PBS空白樣品中掃描250-800nm的樣品。
1.未綴合的染料也可以通過透析與標記的抗體分離。透析不能像凝膠過濾那樣有效快速分離。建議盡可能使用凝膠過濾。
提供材料干燥的染料標記1mg羰基化合物。
所需材料但未供應偶聯緩沖液:1:1甲醇/乙酸三乙銨緩沖液,pH 8.0 Sigma-Aldrich(90358)。
注意:
1. pH會改變反應的標記效率。宜標記發生在pH 7.2。
2.所有溶劑和緩沖液應脫氣。該方案用于用Cy5酰肼試劑標記?7.8μmol的辛醛。
1.在1:1甲醇/ TEAA緩沖液,pH8.0溶液中將二磺基-Cy5酰肼溶液制成1mg / ml并用氮氣沖洗。
2.在1:1甲醇/ TEAA緩沖溶液(pH8.0至1mg / ml)中制備羰基衍生物溶液并用氮氣沖洗。
3.將兩種溶液加在一起并輕輕混合3小時。
4.真空除去反應溶劑。
1.通過反相HPLC純化產物。在DiSulfo - Cy5 650 nm波長處監測。
