产品介绍

AIE细胞膜红色探针是一种基于AIE原理开发的三苯胺类衍生物,具有典型的AIE特性。产品只需简单地和细胞 孵育,即可标记细胞膜。 

产品特性

AIE细胞膜红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细胞膜,在与细胞膜结合前后由于 聚集状态的变化,其荧光强度会产生极为明显的变化,而未与细胞膜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细胞膜红色探针可通过488 nm激发波长激发,并且斯托克斯位移大,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细胞膜红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。

产品性质

产品优势

1、细胞毒性相对较小,可以进行活细胞及固定细胞成像; 

2、强抗光漂白能力,40 次共 15 分钟的激光扫描,发射荧光强度不变; 

3、背景噪点低,快速成像。 

实验方法

1、染料储备液准备:短暂离心后,将染料溶液适当分装后避光保存于-20℃或更低温度,储备液浓度为 10mM; 

2、染料工作液准备:取1 µL AIE细胞膜红色探针储备液加入到1-2 mL 细胞培养液或适当的缓冲液中(例如 PBS),得到终浓度5-10 μM 的AIE细胞膜红色探针工作液; 

3、细胞染色。适量的工作染液孵育贴壁细胞 30 min(最好置于细胞培养箱中),PBS清洗三次;对于 固定细胞,细胞固定后,用适量工作染液孵育固定细胞 10 min, PBS清洗三次;染完后用共聚焦荧光显微镜 或荧光显微镜观察,激发波长设为488 nm;收集600-700 nm的信号。 

注意事项

1、使用前请先短暂离心; 

2、第一次使用时请先配置好母液后分装,于-20℃保存,避免反复冻融; 

3、为了您的安全和健康,请穿实验服并戴一次性手套操作; 

4、本品不适用于通透液处理的固定细胞; 

5、本品仅适用于科研用途。


AIE Membrane Red Probe is a triphenylamine derivative developed based on the AIE principle and has typical AIE characteristics. The product only needs to be simply incubated with cells to label the cell membrane.

Product Characteristics

AIE Membrane Red Probe has excellent aggregation-induced emission properties and can specifically label the cell membranes of various cells. Due to the change in the aggregation state after binding to the cell membrane, its fluorescence intensity will undergo extremely obvious changes, while the fluorescent probes that do not bind to the cell membrane basically do not emit fluorescent signals.

Different from common dyes, AIE Membrane Red Probe can be excited by an excitation wavelength of 488 nm, and has a large Stokes shift, which can be clearly distinguished from other dyes, reducing the possibility of monochromatic color in imaging. At the same time, AIE Membrane Red Probe has good biocompatibility and high imaging concentration, and can still ensure stable fluorescent signal output in the state of multiple scans, which is very suitable for multiple imaging.

Product Properties

Molecular Weight527.16 g/mol
Purity> 98% (HPLC)
Working Concentration5 - 10 μM
Full width at half maximum550 nm - 690 nm
Maximum Absorption/Emission Wavelength (nm)λabs = 493 nm / Em = 610 nm

Product Advantages

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

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

3.Low background noise, 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. The concentration of the stock solution is 10 mM;

2.Preparation of working dye solution: Take 1 μL of AIE Membrane Red Probe stock solution and add it to 1-2 mL of cell culture medium or an appropriate buffer (such as PBS) to obtain an AIE Membrane Red Probe working solution with a dye concentration of 5-10 μM;

3.Cell staining: Incubate adherent cells with an appropriate amount of the working solution for 30 minutes (preferably in a cell culture incubator), and wash with PBS three times; for fixed cells, after cell fixation, incubate the fixed cells with an appropriate amount of the working solution for 10 minutes, and wash with PBS three times; after staining, observe with a confocal fluorescence microscope or a fluorescence microscope, set the excitation wavelength to 488 nm, and collect signals at 600-700 nm.

Precautions

1.Centrifuge briefly before use;

2.When using for the first time, prepare the mother solution, aliquot it, 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 not suitable for fixed cells that have undergone permeabilization treatment;

5.This product is only for scientific research use.
