One of the challenges with multiplexing fluorophores in biological assays is being able to reliably distinguish the signal of one fluorophore from another. The complication of working with fluorophores with significant spectral overlap is exacerbated when using fluorescent filters or fixed bandwidth monochromators, which provide little flexibility in optimizing signal and minimizing background. Variable bandwidth monochromators provide a powerful alternative that enables fine control over the light range by which fluorophores are excited and emitted light is collected, which in turn allows signal to be more reliably deciphered. BioTek offers a fleet of hybrid-plate readers including the Synergy H1, Neo2, and Cytation, which offer the most flexibility when assaying with multiple fluorescent probes.

Cellular behavior is complex and dynamic. While end-point assays provide a single snapshot of this behavior, it is only when live cells are continually monitored that a more complete understanding of this behavior is realized. At issue, however, is the duration of these dynamics which can occur over seconds, as in the case of intracellular calcium signaling; or continuously, such as the proliferation of a population of cells.

Nucleic acids are the building blocks of life in all living things, from plants and animals to bacteria and viruses. In research, it’s important to quantify nucleic acids prior to downstream processes like sequencing, restriction enzyme digestions and ligations, PCR and qPCR along with many other applications. Along with determining nucleic acid concentrations, it’s also important to calculate the ratio of nucleic acid to protein to ascertain the purity of the nucleic acid before using the sample in subsequent analyses.

Phenotypic cellular analysis is a critical area of biological research. Numerous applications require quantifying the number of “spots” per cell, including DNA damage, autophagosomes, endosomes, and mitochondria. These evaluations are often done by hand, which is highly subjective and can be tedious. In this webinar we will describe using an automated image based approach for rapid, objective quantification of various assays that use object spot counting analysis including autophagy, mitochondria membrane potential, genotoxicity, and others.

Enzyme-linked immunosorbent assay (ELISA) is an antibody-based reaction that allows the detection and quantitation of numerous analytes with the same basic assay process. The reaction uses a solid surface, typically a microplate, to immobilize the analyte. Once immobilized, unwanted materials can be removed by washing and the remaining analyte quantitated. The assay technology uses antibodies in conjunction with enzyme-catalyzed amplification to provide high specificity and high sensitivity. Here we will describe the basic process steps of ELISA, best laboratory practices along with troubleshooting tips for common problems. In addition, some of the devices and instrumentation used with this assay technology will be described.

The use of cells cultured into a three-dimensional (3D) configuration continues to gain acceptance within multiple areas of life science research and drug discovery. Assay procedures commonly performed with two-dimensional (2D) cultured cells are rapidly migrating to 3D because of the reestablishment of cell-cell and cell-extracellular matrix (ECM) interactions, and in vivo-like results these cell models afford. Examples include cell migration studies, stem cell differentiation, and toxicity assessments.

Characterizing cell proliferation is a crucial aspect of biological research and therapeutic drug development. Most current cell proliferation assays rely on indirect biochemical metrics that are limited by artifacts or imaging-based endpoint measures.
