一般描述

5-（和-6）-羧基荧光素二乙酸酯N-琥珀酰亚胺酯（CFSE）是一种荧光染料，可透膜。它通过与细胞内分子之间进行共价结合来标记细胞。CFSE可以用于追踪淋巴细胞的迁移和增殖。

应用

5(6)-羧基二乙酸荧光素 N-琥珀酰亚胺酯（CESE）是一种胺反应性荧光探针，可用于对细胞染色，特别是免疫细胞，以便在流式细胞术等应用中进行分析。经过脱乙酰化形成绿色荧光偶联物。
5-双乙酸荧光素N-琥珀酰亚胺酯可用于：
  • 标记细胞以进行流式细胞术
  • 在淋巴细胞增殖测定中
  • 确定细胞内或叶绿体中细胞内的pH值
  • 标记亚马逊利什曼原虫 和大利什曼原虫

作为胺反应性标记物用于细胞的长期追踪。经过脱乙酰化形成绿色荧光偶联物。

生化/生理作用

5（6）-羧荧光素二乙酸酯N-琥珀酰亚胺酯可用作酯酶活性指标。

包装

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. At what concentration is Product 21888, 5(6)-Carboxyfluorescein diacetate N-succinimidyl ester, soluble in DMSO?

    We have found 5(6)-Carboxyfluorescein diacetate N-succinimidyl ester to be soluble in DMSO at a concentration of 1 mg/mL.

  4. What is the ratio between the (5) and (6) isomer of Product 21888, 5(6)-Carboxyfluorescein diacetate N-succinimidyl ester?

    Our Quality Control group does not routinely report the ratio; however, it is very likely that both isomers are present.

  5. Is Product 21888, 5(6)-Carboxyfluorescein diacetate N-succinimidyl ester, light sensitive?

    Yes. The powder and solutions (especially solutions) should be kept protected from ambient light whenever possible.

  6. Is Product 21888, 5(6)-Carboxyfluorescein diacetate N-succinimidyl ester, fluorescent? Are conjugates of this compound fluorescent?

    No. This compound and conjugates of this compound become fluorescent only when acted upon by an enzyme such as esterase. The enzyme removes the acetate groups.
