What does a MetaFLEX do?

It measures the parameters most important in cell culture: pH, Glucose, Lactate, pCO2, pO2, and electrolytes. Based on Radiometer1’s leading point-of-care blood gas analyzer technology, the MetaFLEX is a powerful technology for the measurement of take action parameters that impact cell viability.

What is Vi-cell?

The Vi-Cell XR Cell Viability Analyzer is a video imaging system used to analyze yeast, insect and mammalian cells. It automates the trypan blue exclusion protocol, in which dead cells take up the dye while live cells do not, and provides data on percent viability and cell counts.

What is a sensor cassette?

The Vi-CELL MetaFLEX sensor cassette contains sensors for the tests (except for the oximetry and bilirubin tests). It uses thick-film sensor technology and miniaturized sensors to enable direct measurements of glucose and lactate from a 100 μL sample (65 μL sample plus 35 μL tare).

How do you test cell viability?

Typically, cell viability assays provide a readout of cell health through measurement of metabolic activity, ATP content, or cell proliferation. Cell viability can also be assessed using cell toxicity assays that provide a readout on markers of cell death, such as a loss of membrane integrity.

How does VI-cell XR work?

An Image Analysis Solution Utilizing the latest in video capture technology and sample handling, the Vi-CELL XR takes the cell sample and delivers it to a flow cell and camera for imaging. The Vi-CELL XR will then capture up to 100 images for its determination of cellular viability.

How long is the ABL90 flex sensor cassette stable onboard the ABL90 Flex?

30 days
In addition there is onscreen user guidance. Choose from cassettes with 100, 300, 600, 900 or 1200 samples. The ABL90 FLEX analyser is easy to maintain, with up to 30 days in-use lifetime of consumables.

Why do we measure cell viability?

The measurement of cell viability plays an essential role in all forms of cell culture. Sometimes, it is the sole purpose of the experiment, for example, in cytotoxicity assays. Alternatively, cell viability can be used to correlate cell behavior to cell number, providing a more accurate picture of cell metabolism.

How do you check cell viability?

Measuring Cell Viability By Flow Cytometry Typically, a membrane-impermeable dye like propidium iodide is used to identify dead or dying cells with damaged membranes and a viability dye like calcein-AM used to label live cells.

What cell viability tells us?

Cell viability is a measure of the proportion of live, healthy cells within a population. Cell viability assays are used to determine the overall health of cells, optimize culture or experimental conditions, and to measure cell survival following treatment with compounds, such as during a drug screen.

What is the principle of cell counter?

The traditional method for counting cells is electrical impedance, also known as the Coulter Principle. Whole blood is passed between two electrodes through an aperture so narrow that only one cell can pass through at a time. The impedance changes as a cell passes through.

What is the role of cell counter?

Cell counters, as the name implies, are tools for counting live and/or dead cells in a culture. Any researcher who works in a cell culture hood needs some sort of cell counting solution, whether to determine cell concentration prior to cell passage, or to assess cell viability following drug treatment.

What is meant by viability test?

What is viability testing. Seed or plant viability is the measure of how many seeds or how much plant material in a lot are alive and could develop into plants that will reproduce under appropriate field conditions.

What affects cell viability?

Factors studied included temperature, level of dissolved oxygen, nutrient depletion, and waste product accumulation. Growing cells at temperatures 3-9 degrees lower than optimum (37 degrees C) increased viability but monoclonal antibody production was lowered.

What is Coulter Counter used for?

Coulter developed a technology for counting and sizing particles using impedance measurements. The technology was principally developed to count blood cells quickly by measuring the changes in electrical conductance as cells suspended in a conductive fluid passed through a small orifice.

What is 3 part hematology analyzer?

A 3-part hematology instrument provides enough information for typical physician office laboratories. With a simple CBC, the neutrophil and lymphocyte counts will answer the question of a viral infection or a bacterial infection that can be treated with antibiotics.

How cell counting is performed?

Cell counting can be performed either by manually using a hemocytometer, or by using an automated cell counter. Read more on cell viability and cytotoxicity assays in the Protocols section below. For over 100 years the hemocytometer has been used by cell biologists to count cells.

What are the advantages of cell counters?

Existing automated cell counters have the advantage of largely removing human subjectivity from the cell counting workflow. They are also often faster than counting manually and can count a larger number of cells, increasing statistical accuracy.

What are the different types of viability?
