What Are Neutralizing Antibody (NAb) Assays? Neutralizing antibodies (NAbs) are a subset of anti-drug antibodies (ADAs) that play an important role in evaluating the immunogenicity, safety, and efficacy of a drug product. While most drugs carry a low risk of eliciting NAbs and do not require a validated NAb…

When it comes to drug discovery, compound screening experiments are the first big step in figuring out whether a new molecule has real therapeutic potential. But the truth is, it’s not enough to simply “run the experiment and see what happens.” The way you design the study—everything from which concentrations…

Why Sample Matrix Choice Matters Choosing the right sample matrix is one of the most critical decisions when designing a flow cytometry assay.  Each option offers unique advantages and limitations that can directly impact data quality, logistics, and study outcomes. Flow cytometry requires intact, viable cells.  The power of flow…

Why Immunogenicity in Drug Development Matters Immunogenicity, why do we keep talking about it? Immunogenicity can, in the simplest of terms, be described as a subject’s ability to generate antibodies specific to the dosed protein therapeutic. Immunogenicity can be either a wanted or unwanted reaction. Wanted immunogenicity is the desired…

If you’ve worked in drug development, you already know that the road from discovery to clinical success is long, expensive, and rarely linear. One of the most pivotal checkpoints in that journey is cytotoxicity testing. Whether you’re developing a small molecule, a biologic, or a cell therapy like CAR‑T, the…

Locked Nucleic Acids (LNAs) are RNA analogs that provide more stable Watson-Crick base-pairing. LNA ribonucleotides can be added into RNA and DNA oligonucleotides to increase the affinity of these oligonucleotides for their complementary sequences. In addition, these LNA present oligonucleotides have extraordinary single-nucleotide discrimination as well as enhanced stability, as…

Screening experiments have become the backbone of modern drug discovery and biological research, enabling the evaluation of thousands of compounds simultaneously. However, screening success hinges on two critical factors: (1) selecting appropriate cellular models and (2) designing robust experimental frameworks. Poor choices can lead to irreproducible results, failed clinical translation,…

In biomarker-driven drug development, selecting the right assay format is critical for generating reliable data that informs scientific and clinical decisions. Whether quantifying proteins, immune cell subsets, or complex molecular signatures, the choice between off-the-shelf and customized assays has direct implications for timelines, costs, and how well the assay performance…

In the ever-evolving landscape of drug development, biomarkers have emerged as critical tools for the mechanism of action, early proof of mechanism, safety, predictive, efficacy, and monitoring treatment response. As the field advances, two major classes of biomarkers have come to the forefront: soluble biomarkers and cellular biomarkers. While…

In the process of drug discovery, an IC₅₀ assay serves as a pivotal component in the development of cutting-edge therapeutics. An effective assay can quantify the potency of compounds, enable side-by-side comparisons with competing compounds, and track how a compound performs over time. Quantifying compound inhibition also assists with pre-clinical…
