Identifying and Resolving the Sources of Hemacytometer Counting Error through Automation

It’s White Paper Wednesday! This month’s featured white paper: Identifying and Resolving the Sources of Hemacytometer Counting Error through Automation The hemacytometer persists as the gold standard for laboratory cell counting. First utilized in 18th century France as a means to analyze patient blood samples, the hemacytometer has gone through a series of major developments over the past hundreds of years, creating a modern instrument that is more accurate and easier to use than its predecessors. The hemacytometer remains an integral part of all cell-based research, and yet sources of error inherent in its design and utilization persist. Those sources [...]

Accurately Count PBMC and Measure Viability in Presence of Residual RBC

It’s White Paper Wednesday! This month’s featured white paper: Accurately Count PBMC and Measure Viability in Presence of Residual RBC In this work, we have developed an image cytometry method for detecting and monitoring the cell expansion and differentiation of articular chondrocytes in primary culture. First, the feasibility of utilizing image cytometry for detection of fluorescent is shown by comparing measured fluorescent positive cell populations to flow cytometry. Next, articular chondrocyte cultures were established in multi-well plates from either single or Cyan/eGFP double reporter mouse lines and grown for 20 days to test the utility of the fluorescence-based image cytometry system. [...]

Counting Chambers – Is Reusable Really Better?

Let’s talk about counting chambers for a minute. You might call it a slide, a consumable or a chip. It’s all the same to us. Nexcelom’s first product was a disposable hemacytometer CP2. The rationale was the existing product available for researchers was the hemacytometer, and that was riddled with problems and concerns. They were (and are!) expensive, they are prone to breaking and could be time consuming to wash. Everyone has a bad day from time-to-time, when their mind is somewhere else. It’s not too hard to imagine that human error would come into play and result in a [...]

Get Flow Results without Flow Cytometry

Cellometer Vision CBA Image Cytometry System Incorporation of FCS Express 4 Software (De Novo Software) into the Vision CBA Analysis System has enabled users to conduct image-based analysis of cell-based assays requiring enhanced gating for the most accurate, reliable, and reproducible results. Side-by-side comparison of results for apoptosis, cell cycle, mitochondrial potential, autophagy, ABC transporter assays, aggresome detection, CD4+ / CD8+ immunophenotyping, and other assays has shown Cellometer image-based analysis results to be comparable to flow cytometry. Flow core labs can utilize the Vision CBA instrument to pre-screen samples prior to sorting and flow cytometry analysis and to [...]

Easily Transition from Manual Cell Counting to Automated Cell Counting

Cellometer Auto 2000 Cell Viability Counter When performed correctly, correlation studies make it easy to transition from manual counting to Cellometer automated cell counting. Because Cellometer Auto 2000 and Cellomether Vision utilize a dual-fluorescence detection system, fresh blood and bone marrow samples can be analyzed for total nucleated cell concentration and viability without lysing, thus simplifying the testing process and improving the accuracy and consistency of test results. The same method can be used to analyze both fresh and processed samples or users can switch to a more traditional trypan blue method following magnetic separation. Figure 1. [...]
