What is a Cellometer?
The Cellometer Auto 2000 Cell Viability Counter is designed for simple, accurate analysis of nucleated cells (including PBMCs, splenocytes, stem cells) in peripheral blood, cord blood, bone marrow, and other heterogeneous samples.

How does a Cellometer work?
The Cellometer K2, powered by Matrix software, utilizes brightfield imaging and dual-fluorescence imaging to quickly and accurately identify and count individual cells. Cell count, concentration, diameter, and % viability are automatically calculated and reported.
What does Trypan Blue do?
Trypan blue is a diazo dye that has been widely used to color dead tissues or cells selectively. The mechanism of trypan blue staining is based on it being negatively charged and not interacting with cells unless the membrane is damaged.
What are the advantages of automated cell counter?
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 is a cell counter used for?
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 could cause an automated cell counter to malfunction?
An automated cell counter is designed to visualize and detect cells accurately and with high precision. Using cell concentrations that are too low or too high is generally associated with counting errors, specifically with a traditional hemocytometer.
Are cell counts accurate?
It is important that cell counts be accurate, consistent, and fast, particularly for quantitative measurements of cellular responses. Despite this need for speed and accuracy in cell counting, 71% of 400 researchers surveyed(1) who count cells using a hemocytometer.
How accurate are blood cells counts?
Nielsen, Smyth, and Greenfield concluded that in order to obtain an accuracy of 10%, 15%, and 20% in hemacytometer counting, the number of samples necessary were 7, 3, and 2, in addition to, 180, 200, and 125 cells counted per sample, respectively.
What is disadvantage automated cell counter?
Disadvantages of Automated Hematology Analyzer Comments on red cell morphology cannot be generated. Abnormal red cell shapes (such as fragmented cells) cannot be recognized. Erroneously increased or decreased results due to interfering factors. Expensive with high running costs.
How much blood count is normal?
Results
Red blood cell count | Male: 4.35-5.65 trillion cells/L* (4.35-5.65 million cells/mcL**) Female: 3.92-5.13 trillion cells/L (3.92-5.13 million cells/mcL) |
---|---|
Hematocrit | Male: 38.3-48.6 percent Female: 35.5-44.9 percent |
White blood cell count | 3.4-9.6 billion cells/L (3,400 to 9,600 cells/mcL) |
Should I be worried about abnormal blood test?
If you have some results at the high or low end of normal, ask your doctor if you should repeat the test or investigate them further. But remember: “Each test has its own rules,” says Dr. Salamon. “Leave the interpretation up to your doctor.”
