Reversible cytoplasm blue fluorescent dye

CytoSeeing

Cat.# FDV-0017 / Size: 1mg


CytoSeeing는 배지에 첨가하는 것만으로 세포질을 신속하게 염색하는 새로운 가역적 형광 염색 시약입니다. 

염색된 세포질을 형광 관찰 한 후, CytoSeeing을 포함하지 않는 배지로 교환하는 것만으로 세포 내에서 쉽게 형광 염색시약을 제거 할 수 있습니다. 따라서, 연이어 다른 형광 프로브로 세포 염색, 관찰이 용이합니다.


CytoSeeing is a newly developed fluorescent dye, which can stain cytoplasm promptly by just adding

to culture medium. After observation, fluorescent dye can be easily removed by replacing medium

which does not contain CytoSeeing.

 

This product is commercialized based on the research result of Hokkaido University Faculty of Science.


Background

It is well known that morpholgy change of nuclear and cytoplasm are related to differentiation, function

and signal response of cells. Conventional cytoplasm staining dyes are used for cell tracking.

Therefore, once dyes are incorporated into cells, the dyes remain in cytoplasm even after medium change.

The dyes are diluted in the course of cell division, and disappear after 3 to 6 population doubling.

If dyes remained in the cells, it is difficult to observe the cell withother probes after live cell imaging.

 

CytoSeeing overcomes this conventional problem. CytoSeeing can be washed out by just replacing medium without

containing CytoSeeing.


Features 

 Easy protocol

  - Just add CytoSeeing to culture medium.

 No staining on nucleus

 Compatible with green and red fluorescent dyes

  - CytoSeeing can be detected by fluorescence filter for DAPI.

 Little effect to cell function

 Removable

  - Just replace with fresh medium without containing CytoSeeing. Cells can be used for further assays.

 Compatible with both adhesive and suspension cells.

Protocol Overview

1. Culture cells

2. Add CytoSeeing solution to medium, with the final concentration from 10 μM to 50 μM.

4. Observe cells by fluorescent microscopy.

5. If needed, remove CytoSeeing by replacing with fresh medium (without containing CytoSeeing).


Example Data 


Fig. 1 Multiple staining of Endoplasmic Reticulum (ER) or Golgi Body

A549 cells are stained with ER probe (Magenta) or Golgi probe (Yellow) after staining by CytoSeeing (50 μM).

CytoSeeing (Cyan) stains entire cytoplasmand fluorescence intensity is increased under hydrophobic environment

such as in ER and Golgi Body.


Fig. 2 Incorporation and distribution of CytoSeeing in A549 cells by time course

a) CytoSeeing (10 μM) was added and incubated. CytoSeeing was completely incorporated into cell by 9 minutes.

b) CytoSeeing incorporated cells were washed and incubatedin fresh medium (without CytoSeeing).

    Almost CytoSeeing was removed in 30 minutes.
