Description
Technical field
The present invention relates to biotechnology more particularly to a kind of live cell fluorescent colouring methods.
Background technology
Cell dyeing is an important technical for observing cell, during cell dyeing, generally requires much to grasp
Make step, using traditional cell dyeing method, be unfavorable for the Fluorescent Staining Observation of living cells.Cell after egg mother cell is fixed
Death has occurred, morphosis is fixed, then the step of progress fluorescent staining, and the step for being also finally most critical is envelope
Piece.Conventional egg mother cell mounting is that a thin layer of glycerine is applied on glass slide, and then egg mother cell is moved into glycerine, then
The coverslip that a small amount of lanolin is moistened with quadrangle carries out tabletting, and mounting is completed.But fluorescence dye is carried out for egg mother cell living
During color, mounting cannot mounting by a conventional method.After the completion of egg mother cell living is dyed with chemical dye, due to not solid
It is fixed, if continue with the method mounting cell of routine will crenation degeneration can even crush and seriously affect observation result.
Invention content
The problem of present invention is in order to overcome conventional cell dyeing to cause living cells crenation degeneration, influence observation, provides one
Kind live cell fluorescent colouring method.
To achieve these goals, the present invention uses following technical scheme:
A kind of live cell fluorescent colouring method, includes the following steps:
(1)Living cells is dyed, 25 ~ 35min is cultivated in staining reagent,
(2)After the completion of dyeing, living cells is transferred in washing lotion and is cleaned 2 ~ 5 times;
(3)By the living cells cleaned on glass slide smear cell isotonic solution, coverslip in pressure;
(4)It makes marks, uses confocal laser scanning microscope immediately.
The present invention is improved innovation to conventional mounting method, and glycerine is replaced using a kind of cell isotonic solution in mounting
The cellular morphology on glass slide is remained unchanged, overcomes the problem of cell shrinkage denaturation.
Preferably, the living cells is egg mother cell living.
Preferably, step(1)In, the method cultivated in staining reagent is:It is horizontal to the generation of ROS in egg mother cell
It is detected, with oxidation-sensitive fluorescence probe under 37 ~ 38 DEG C of temperature conditions, is incubated 25 ~ 35min.
Preferably, the oxidation-sensitive fluorescence probe is dichlorofluorescein DCFH, according to DCFH:The volume ratio of DPBS is
1:600 ~ 800 proportions are made.
Preferably, step(2)In, the washing lotion is DPBS washing lotions.
Preferably, step(3)In, the cell isotonic solution is DPBS buffer solutions.
Preferably, step(3)In, before covered, suitable lanolin is dipped in coverslip surrounding.
DPBS buffer solutions have salt balance, adjustable appropriate pH cushioning effect, are cell isotonic solution, in fluorescent staining
In for washing away the fluorescent dye of cell surface, so replacing glycerine, such energy with DPBS buffer solutions when living cells mounting
The morphosis and biological nature of cell are enough protected, and the lanolin that coverslip quadrangle is moistened with will be more than the lid of conventional mounting
Slide, progress ensure that cell is not crushed.
Therefore, the present invention has the advantages that:Innovation is improved to conventional mounting method, in mounting using thin
Born of the same parents isotonic solution DPBS buffer solutions replace glycerine, remain unchanged the cellular morphology on glass slide, overcome cell shrinkage denaturation
Problem.
Specific embodiment
Below by specific embodiment, the technical solutions of the present invention will be further described.
In the present invention, if not refering in particular to, all devices and raw material is commercially available or the industry is common are following
Method in embodiment is this field conventional method unless otherwise instructed.
Embodiment 1
