Introduction to Digital SPR and its use in assessing the binding kinetics of DART (Drugs Acutely Restricted by Tethering).


Digital SPRTM is a next-generation technology for characterizing biomolecular interactions. By combining digital microfluidics (DMF) with SPR, digital SPR systems can effectively bypass common challenges found in traditional SPR and BLI platforms.
Understanding drug mechanisms in complex systems, particularly in the brain, remains challenging despite advancements at the molecular level. Yet, cell-specific technologies like DART provide a promising solution, enabling targeted drug delivery to genetically defined neuronal cell types, thereby allowing the observation of the drug effects on brain dynamics and animal behavior. (Shields et al., bioRxiv, 2022, Shields et al., Science, 2017).
The underlying principle of DART technology is the covalent interaction between a protein and its target chemical molecule. In this webinar, we will discuss the optimization of the covalent capture affinity of DART, and the subsequent functional analysis of binding kinetics, using digital SPR.
  • What digital SPR is and how it works.
  • See how data quality and throughput are maximized using the latest advances in digital SPR to eliminate artifacts, optimize accuracy, and automate tedious, error-prone sample preps.

LevitasBio Webinar - Elucidating the Leptomeningeal Immune Response to Cancer With Single-Cell Proteogenomic Profiling


Metastases to the central nervous system from solid primary tumors are a frequent and fatal complication of cancer with limited therapeutic options. Despite the advent of immunotherapy, it remains largely unknown whether and how metastatic cells in the brain and surrounding cerebrospinal fluid (CSF)-filled leptomeninges interact with the immune system.

To approach these interactions in an unbiased manner, Jan Remsik and his colleagues profiled an unexpectedly heterogeneous population of cell types in human and mouse CSF with single-cell analytics. These samples were inherently challenging to process due to a relatively low number of cells from each human subject or mouse collection, extreme cell fragility, and contamination by myelin and other unwanted debris in the case of the mouse samples.

Since FACS-sorted samples suffered an unbearable amount of stress that prevented their processing, the team used the LeviCell 1.0 system to deplete the debris and enrich for viable cells in stress-free conditions.

Incorporating the LeviCell run into their pipeline resulted in the capture of sufficient numbers of high-quality cells for CITE-seq.

Such a proteogenomic approach, combining more than 100 cell surface signals with whole transcriptome sequencing, allowed Remsik and his colleagues to elucidate the response of the CSF immune system to cancer at an unprecedented resolution.

Utilizing RNA and DNA plate-seq workflows for low-input or rare single-cell genomics

Utilizing RNA and DNA plate-seq workflows for low-input or rare single-cell genomics

Single-cell studies in recent years have revealed that organisms are composed of thousands of unique and unrepeatable cell types. Conducting single-cell genomic analyses using next-generation sequencing (NGS) methods, similar to low-input sequencing, has traditionally been challenging due to the limited amount of genomic DNA present in single cells. This limitation becomes even more pronounced when the studied population is small, such as in the case of rare cells. High-fidelity (HiFi) and high-quality genomic DNA amplification is essential for single-cell sequencing, which is strongly dependent on the quality of the isolated cells.

Therefore, the method used to isolate single cells becomes an important consideration for ensuring cell viability and nucleic acid integrity. Namocell’s patented gentle sorting and cell enrichment technology overcomes the aforementioned challenges to provide a higher quantity and quality of cell samples for sequencing. As a result, a complete and accurate picture of the studied samples can be achieved.

Whether you’re a beginner or expert in single-cell analysis, join this informative webinar to learn about the considerations, challenges and new technologies for low-input or rare single-cell genomics, followed by a discussion on the latest tips for low-input NGS.

Fast, Gentle and Easy Single Cell Isolation

Single cell sorting and isolation has traditionally been a bottleneck in the workflows for single cell cloning, single cell genomics, rare cell isolation, synthetic biology and other applications. Existing techniques such as fluorescence-activated cell sorting (FACS) often leads to compromised cell viability and poor outgrowth, contamination, clogging, in addition to the operational complexity and high maintenance requirement, while manual limiting dilution is inefficient, unreliable and highly labor-intensive. As such, there has been an urgent need for fast and easy single cell dispensing technology that is at the same time gentle to the cells and can preserve their viability and integrity. There is also a need for quick sorting of tens of thousands of cells for single cell genomics, such as sample prep for 10x Genomics workflow.

In this presentation, the speaker will discuss an innovative technology to address these needs. It combines the benefits of three key technologies: microfluidics, flow cytometry and liquid dispensing. The unique combination of these techniques enables users to accomplish single cell sorting and dispensing in one step, providing fast, easy and gentle sorting and isolation of single cells. This will simplify and empower a number of single cell applications, including cell line development, single cell genomics and proteomics, cell line engineering and CRISPR, monoclonal antibody development, synthetic biology, and rare cell isolation such as circulating tumor cells (CTCs) and circulating fetal cells.

Register for this webinar to discover how this technology can help optimize a single cell workflow and deliver desired results.
