Learn all about absorbance detection – how it works, how it’s measured, and how it can be used to calculate concentration. We also provide information on common absorbance applications and assays including ELISAs, nucleic acid and protein quantitation, and microbial growth.
AlphaScreen® Technology is a homogeneous, high-throughput method for detecting intramolecular binding. Donor and acceptor beads are attached to biomolecules, and when the beads are brought into proximity (via binding), a cascade of chemical reactions occurs, amplifying a signal that is detected on the SpectraMax® i3x and Paradigm® Multi-Mode Microplate Readers.
Cell viability refers to the number of healthy cells in a population and can be evaluated using assays that measure enzyme activity, cell membrane integrity, ATP production, and other indicators. These methods can employ luminescent, fluorescent, or colorimetric readouts as indicators of general cell viability or even specific cellular pathways. Cytotoxicity and cell viability assays are often used to assess a drug or other treatment’s effect, and are valuable tools in the search for new therapeutics, as well as advancing our understanding of how normal cells function.
Transition of a cell through the cell cycle can be monitored using fluorescently labeled cell cycle proteins that are cyclically expressed and degraded. FUCCI technology is based on the overexpression the cell cycle-dependent proteins geminin and Cdt1, respectively fused to a green fluorophore and a red fluorophore. Cdt1 levels peak in G1 phase, so cells in G1 appear green; geminin levels rise in late S, G2 and M phase, so cells in these phases appear red.
Cell migration, the movement of cells from one location to another, is a critical component of both normal and abnormal biological processes. The migration of fluorescently labeled cells from one area of a microplate well to another can be monitored using a cellular imaging system. Automated analysis software calculates the amount of cell migration in each well.
Cellular signaling allows cells to respond to their environment as well as to communicate with other cells. Proteins located on the cell surface can receive signals from the surroundings and transmit information into the cell via a series of protein interactions and biochemical reactions that comprise a signaling pathway. Multicellular organisms rely upon an extensive array of signaling pathways to coordinate the proper growth, regulation, and functioning of cells and tissues. If signaling between or within cells is dysregulated, inappropriate cellular responses may lead to cancer and other diseases.
The drug discovery landscape is shifting, with more scientists centering cell line development, disease models, and high-throughput screening methods around physiologically-relevant 3D cell models. The reason for this is clear: Using cellular model systems in research that closely mimic patient disease states or human organs can bring life-saving therapeutics to market – faster.
Enzyme-linked immunosorbent assays (ELISAs) are used to measure the amount of a specific protein, using a microplate format, and results are most often detected via absorbance in the visible wavelength range. Chemiluminescent and fluorescent ELISA formats offer enhanced sensitivity for accurate quantitation of less abundant analytes.
Learn all about fluorescence detection – what it is, how it works, and the instruments used to measure the fluorescence of a sample. We also cover many fluorescence-based assays including cell viability, GPCR activity, and fluorescent nucleic acid quantification.
Fluorescence polarization (FP) is a technique that is widely used to monitor binding events in solution. It can be used to assess biomolecular interactions, including protein-antibody binding and DNA hybridization, as well as enzyme activity, and it has been adapted to basic research as well as high-throughput screening.
In therapeutic protein engineering and cell line development, IgG quantification is the process of measuring the amount of immunoglobulin G (IgG), a common class of therapeutic proteins, produced by a genetically modified cell line. This is important for evaluating and monitoring the productivity of the cell line and selecting the best candidate for further development of therapeutic antibodies.
Kinases are one of the most critical targets in drug discovery today. These enzymes are key components in cellular signaling pathways, and disruption to their function causes a variety of diseases, such as metabolic diseases, certain cancers, and cardiac disease. The functionally related phosphatases and phosphodiesterases are also important screening targets.
Learn about luminescence detection – what it is, how it works, and the advantages of luminescence over other detection modes. We’ll cover key luminescence-based assays including dual-luciferase reporter gene, chemiluminescent ELISA, cytotoxicity, and BRET.
Microbes, including bacteria, have been estimated to make up about 15 percent of the earth’s biomass, and microbes in the human body outnumber human cells by 10 to 1. These microorganisms provide great benefit to us and are also vital to many fields of research from medicine to alternative energy production. On the other hand, monitoring for microbes and the toxic substances they produce is necessary to ensure the safety of pharmaceutical products. Scientists whose research relies on mammalian cells must carefully monitor these cultures for unwanted microbial contaminants to ensure that their experimental results are reliable.
Nanomaterials are typically less than 100 nm in diameter, small enough to penetrate mammalian cells. They can be synthesized in many shapes, such as rods, tubes, and particles, as well as in different materials. Targeting or therapeutic molecules can be readily attached to nanoparticles, and when these are delivered systemically, the targeting molecules enable detection of certain cell populations, such as tumor cells, while attached therapeutic compounds can act on the targeted cells.
Nucleic acids are large biomolecules common to all known life forms. Deoxyribonucleic acid (DNA) consists of a double strand of pairs of nucleotides, while ribonucleic acid (RNA) is typically a single strand. In DNA, the nucleotides are adenine, cytosine, guanine, and thymine, while RNA contains uracil instead of thymine. DNA makes up the genetic material of all organisms, encoding the information cells need to synthesize proteins.
Protein detection, quantitation, and analysis are central to the investigation of a wide variety of biological processes. Measuring the concentration of protein is necessary to processes ranging from protein purification and labeling to sample preparation for electrophoresis. Protein can be quantitated directly via absorbance at 280 nm, or indirectly using colorimetric (BCA, Bradford, etc.) or fluorometric methods offering advantages such as greater sensitivity. To identify and measure a specific protein within a complex sample, for example, serum or cell lysate, an ELISA may be used.
Cancer is a leading cause of death worldwide, but researchers are making enormous strides towards understanding its underlying mechanisms and working towards new treatments. Spheroids, 3D aggregates of cells in culture, have emerged as a valuable research tool that provides more physiological relevance than traditional 2D cell culture.

We have been developing a non-thermal, drug-free tumor therapy called Nano-Pulse Stimulation (NPS) that delivers ultrashort electric pulses to tumor cells which eliminates the tumor and inhibits secondary tumor growth. We hypothesized that the mechanism for inhibiting secondary tumor growth involves stimulating an adaptive immune response via an immunogenic form of apoptosis, commonly known as immunogenic cell death (ICD). ICD is characterized by the emission of danger-associated molecular patterns (DAMPs) that serve to recruit immune cells to the site of the tumor. Here we present evidence that NPS stimulates both caspase 3/7 activation indicative of apoptosis, as well as the emission of three critical DAMPs: ecto-calreticulin (CRT), ATP and HMGB1.
Kufor–Rakeb syndrome (KRS) is caused by loss-of-function mutations in ATP13A2 (PARK9) and characterized by juvenile-onset parkinsonism, pyramidal signs, and cognitive decline. Previous studies suggested that PARK9 deficiency causes lysosomal dysfunction and α-synuclein (α-syn) accumulation, whereas PARK9 overexpression suppresses toxicity of α-syn. However, the precise mechanism of PARK9 effect on lysosomes and α-syn has been unknown. Here, we found that overexpressed PARK9 localized to multivesicular bodies (MVBs) in the human H4 cell line. The results from patient fibroblasts showed that loss of PARK9 function leads to decreased number of the intraluminal vesicles in MVBs and diminished release of exosomes into culture media. By contrast, overexpression of PARK9 results in increased release of exosomes in H4 cells and mouse primary cortical neurons. Moreover, loss of PARK9 function resulted in decreased secretion of α-syn into extracellular space, whereas overexpressed PARK9 promotes secretion of α-syn, at least in part via exosomes. Finally, we found that PARK9 regulates exosome biogenesis through functional interaction with the endosomal sorting complex required for transport machinery. Together, these data suggest the involvement of PARK9 in the biogenesis of exosomes and α-syn secretion and raise a possibility that disruption of these pathways in patients with KRS contributes to the disease pathogenesis.
Stem Cells derived human cardiomyocytes have phenotypic characteristics and electrophysiological profiles similar to those of native human cardiac cells.
