一般描述

Lucifer yellow CH是一种可固定染料，激发光谱和发射光谱分别为430 nm和540 nm。[1]LuciferYellow CH （LYCH）是一种小亲水分子[2]和高荧光染料，用于细胞内染色，以便研究各种类型的细胞。[3]它可作为一种标志物，用于检测平滑肌、胶质细胞和Cajal （ICC）间质细胞中建立良好的紧密连接[2]。[3]

应用

萤黄CH二钾盐用于：
  • 可视化细胞形态[1]
  • 通过划痕标记试验评估间隙连接的细胞间通信活动[4][5]
  • 用作细胞内液的组成部分，即填充树突以显现神经形态[6]
  • 用于细胞内液中，以在细胞内标记记录的神经元[7]

特点和优势

高度荧光染料，可用于标记神经细胞。

Questions

1–2 of 2 Questions  

  1. What is the dye purity for product L0144?

    What is the dye purity for product L0144?

    1 answer

    1. At M-Clarity quality level 100, Product L0144 is evaluated based on appearance, infrared spectrum, solubility, and fluorescence specifications. Please refer to the Certificate of Analysis found on the DOCUMENTATION section of the Product Detail Page: https://www.sigmaaldrich.com/product/sigma/l0144#product-documentation

      Using the results on the specification sheet, dye content can be calculated from the testing performed to determine carbon and nitrogen levels.

  2. What is the stability and shelf life for product L0144, lot SHBN6250 once it has been prepared in a solution?

    1 answer

    1. The product is soluble in water at a concentration of 1 mg/mL, producing a clear, yellow-orange colored solution. It is also soluble in water with heat at a concentration of 10 mg/mL, resulting in a slightly hazy orange colored solution. Additionally, a solution stability test revealed that a solution of L0144 in water at a concentration of 1.7 mg/mL, stored in the dark at room temperature for 32 days, showed no detectable change in the UV-VIS spectrum.
