Best Practice for CellDrop Series Cell Counters

Cell counting can be a laborious process, with slow workflows and strict process control standards. These complications are compounded by elements of subjectivity when it comes to overall count and viability tests. Biologists running tests via hemocytometry or slide-based microscopy must individually carry out measurements, making judgment calls on cell identification or viability, which can

Peripheral Blood Mononuclear Cell Counting

Quantifying and qualifying the viability of primary cells can be difficult via conventional cell counting methodologies (hemocytometry, slide-based microscopy, etc.). Primary cells are cells that have been harvested directly from living tissues and isolated in vitro. They are not modified like artificially preserved cell lines, which makes them a better representation of the cells’ in

Operating Cell Counters with FDA/PI Yeast Assays

Viability is a key metric in determining the activity or metabolism of yeast cells in solution. It is commonly measured using either brightfield microscopy or fluorescent stains like fluorescein diacetate (FDA) and propidium iodide (PI) with both manual and automated cell counters. Fluorescein diacetate is an esterase substrate that can freely permeate the plasma membrane

Manual vs. Automated Cell Counters

Cell counting is a procedure with a choice of numerous diverse techniques, most of which rely on specialized laboratory appliances. Despite the variety of cell counters available for modern-day life science applications, they can typically be divided into one of two sub-groups: manual and automated cell counters. In this blog post, DeNovix compares the benefits

Outlining UV-Vis DNA Quantification

There are numerous methods suitable for quantifying the number of nucleic acids in a sample, but UV-Vis absorbance is the primary method for determining a sample’s concentration and purity of DNA or RNA. Both single- and double-stranded DNA strongly absorb ultraviolet light with a peak absorbance wavelength of 260nm. Simple concentration and purity measurements involve
