Description
Technical field
The present invention relates to cell viability measurement devices in a kind of cell culture.
Background technology
Trypan Blue, for measuring " health status " of the vigor in cell culture, i.e. cell.Cell in suspension
It can be dyed with dyestuff, dyestuff has the property for the cell membrane that cannot penetrate intact cell.Relatively, damage or death
Cell allows dyestuff penetration, therefore can be colored.The conventional method of detection cell viability is that fully diluted cell suspends
Liquid is added in Neubauer cell counting count boards, to determine the ratio of complete and damage cell.The size of cell counting count board is substantially
Corresponding to conventional microscopic slide, tally is further divided into different countings by the groove for being carved with specific dimensions above
Area.Under the microscope, the damaging cells of dyeing and achromophil intact cell can be counted.Multiple count blocks would generally be measured
In cell number and be averaged, to reduce statistical error.Then according to known counting volume and cell suspending liquid thinner ratio
Example backwards calculation is converted into complete and damaging cells absolute magnitude in cell culture.This method be first it is extremely complex,
Because it includes multiple operating procedures.Secondly, accuracy is also extremely restricted.Particularly, the cell number that can be counted
Mesh is very limited, this causes high statistical error.Therefore ought need to describe complete and damaged cell ratio incessantly, it is also necessary to retouch
When stating cellular damage degree, this method of counting is actually inapplicable.But it is possible real to be substantially based on Trypan Blue
It is existing because the dye levels of cell can as the measured value of its degree of injury, especially as process of cell death into
The measured value of exhibition, however, in order to statistically verify this distribution, it is necessary to larger numbers of cell is counted, and it is conventional
Method is very poorly efficient.
For the PCV methods of diagnostic field, PCV represents " packed cell volume capacity (Packed Cell Volume) ", finger pressure
Ratio of the cell mass of contracting in population of samples product.The pcv value of blood is referred to as hematocrit value.Measure hematocrit value
When, it is necessary to blood sample is positioned towards to centrifuge in cylindrical sample cell, until the solids content of blood to compress
Cell mass form is deposited on tube bottom.Fluid contents (also referred to as supernatant) are on cell mass.It is red thin in order to measure
Born of the same parents' specific volume calculates the ratio of volume shared by haemocyte, it is necessary to measure the volume of cell mass.But defect that there are one PCV methods, because
It only detects solid constituent in sample, but does not describe the cell viability in the solid constituent.
The content of the invention
Based on this, it is necessary to provide cell in a kind of cell culture that can efficiently and accurately measure cell viability and live
