产品介绍

AIE内质网黄色探针是一种基于AIE原理的内质网荧光探针,具有典型的AIE特性。产品具有跨膜转运能力,只需 简单地和细胞孵育,即可标记内质网。

产品特性

AIE内质网黄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细胞的内质网,而在与内质网结合前后由于聚 集状态的变化,其荧光强度会产生极为明显的变化,而未与内质网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内质网黄色探针斯托克斯位移大,可以明显其他染料进行区分,减少成像中串色的可能性。 同时AIE内质网黄色探针的生物相容性好,成像浓度高,可在多次扫描的状态仍然保证稳定的荧光信号输出,非常适合多次 成像。

AIE ER Yellow Probe is an endoplasmic reticulum fluorescent probe based on the AIE principle, with typical AIE characteristics. The product has transmembrane transport ability; simply by incubating it with cells, it can label the endoplasmic reticulum.

Figure 1. Imaging effect on HeLa cells

Product Characteristics

AIE ER Yellow Probe has excellent aggregation-induced emission properties and can specifically label the endoplasmic reticulum of various cells. Before and after binding to the endoplasmic reticulum, due to changes in the aggregation state, its fluorescence intensity undergoes extremely significant changes, while fluorescent probes not bound to the endoplasmic reticulum basically do not emit fluorescent signals.
Different from common dyes, AIE ER Yellow Probe has a large Stokes shift, which can clearly distinguish it from other dyes, reducing the possibility of crosstalk in imaging. Meanwhile, AIE ER Yellow Probe has good biocompatibility and high imaging concentration, and can ensure stable fluorescence signal output even during multiple scans, making it very suitable for multiple imaging.
Product Properties

Chemical FormulaC₃₅H₂₇NO₆
Molecular Weight557.60
Full Width at Half Maximum (nm)550 - 625
Working Concentration5 - 10 μM
Maximum Absorption/Emission Wavelength (nm)λabs = 317 nm / Em = 576 nm

Product Advantages

1.Relatively low cytotoxicity, suitable for live cell imaging;

2.Strong anti-photobleaching ability; after 40 laser scans totaling 15 minutes, the emitted fluorescence intensity remains unchanged;

3.Low background signal, enabling rapid imaging.

Experimental Methods

1.Preparation of stock dye solution: After brief centrifugation, aliquot the dye solution appropriately and store it in the dark at -20°C or lower;

2.Preparation of working dye solution: Take 1 μL of AIE ER Yellow Probe stock solution and add it to 1-2 mL of cell culture medium or an appropriate buffer (e.g., PBS) to obtain an AIE ER Yellow Probe working solution with a final concentration of 5-10 μM;

3.Cell staining: Incubate adherent cells with an appropriate amount of the working solution for 40 minutes (preferably in a cell culture incubator). Wash three times with PBS. Observe using a confocal fluorescence microscope or a fluorescence microscope. Set the excitation wavelength to 405 nm and collect signals at 550-600 nm.

Precautions

1.Centrifuge briefly before use;

2.When using for the first time, aliquot and store at -20°C to avoid repeated freezing and thawing;

3.For your safety and health, please wear a lab coat and disposable gloves;

4.This product is only for scientific research use.
