产品介绍

AIE细胞核绿色探针是一种基于AIE原理开发的三苯胺类衍生物,具有典型的AIE特性。
产品特性

AIE细胞核绿色探针具有良好的聚集诱导发光特性,可以特异性标记多种固定细胞的细胞核结构,在与细胞核结合前后由于聚集状态的变化,其荧光强度会产生极为明显的变化,而未与细胞核结合的荧光探针基本不会发射出荧光信号。

与常见染料不同,  AIE细胞核绿色探针斯托克斯位移大,可以明显与其他染料进行区分,减少成像中串色的可能性。同时AIE细胞核绿色探针的生物相容性好,成像浓度高,可在多次扫描的状态下保证稳定的荧光信号输出,非常适合多次成像。

AIE Cell Nuclear Green Probe is a triphenylamine derivative developed based on the AIE principle, with typical AIE characteristics.

Product Characteristics
AIE Cell Nuclear Green Probe has excellent aggregation-induced emission properties and can specifically label the nuclear structures of various fixed cells. Due to the change in aggregation state before and after binding to the nucleus, its fluorescence intensity undergoes extremely significant changes, while the fluorescent probe that does not bind to the nucleus basically does not emit fluorescent signals.


Figure 1. Laser confocal imaging effect diagram on LO2 cells
Different from common dyes, the AIE nuclear green probe has a large Stokes shift, which can be clearly distinguished from other dyes and reduce the possibility of crosstalk in imaging. At the same time, the AIE nuclear green probe has good biocompatibility and high imaging concentration, and can ensure stable fluorescence signal output under multiple scanning conditions, making it very suitable for multiple imaging.

Product Properties

FormulaC₃₃H₃₀N₄O₂²⁺
Molecular Weight513.64 g/mol
Purity≥98% (HPLC)
Working Concentration1- 10 μM
Excitation Wavelength405 nm
Emission Wavelength500 - 600 nm

Product Advantages

  1. Strong anti - photobleaching ability. After 40 times of laser scanning totaling 15 minutes, the emission fluorescence intensity remains unchanged.
  2. Low background noise and fast imaging.

Experimental Methods

  1. Preparation of Dye Stock Solution: Centrifuge briefly. Add 80 μL of high - quality anhydrous DMSO to one tube of AIE nuclear green probe solution. Pipette and mix evenly to obtain an AIE nuclear green probe stock solution with a concentration of 10 mM. After appropriate sub - packaging, store in the dark at - 20 °C or a lower temperature.
  2. Preparation of Dye Working Solution: Take 1 μL of the AIE nuclear green probe stock solution and add it to 1 - 10 mL of cell culture medium or an appropriate buffer (such as PBS) to obtain an AIE nuclear green probe working solution with a final concentration of 1 - 10 μM.
  3. Cell Staining: After cell fixation, incubate the cells with an appropriate amount of the working staining solution for 5 - 10 min. Wash with PBS. Observe with a confocal fluorescence microscope or a fluorescence microscope. Set the excitation wavelength to 405 nm and collect signals at 500 - 600 nm.

Precautions

  1. Please centrifuge briefly before use.
  2. Store at - 20 °C and avoid repeated freezing and thawing.
  3. For your safety and health, please wear a lab coat and disposable gloves during operation.
  4. This product is only for scientific research use.
