Long-term stability testing is very important for understanding the stability of biological products. However, traditional long-term stability tests require many samples and time, and one must wait until the final stages of development. The thermal stability evaluation platform tool Uncle has expanded to include isothermal change measurements in addition to Tm and Tagg measurements, allowing for the differentiation and evaluation of samples that could not be distinguished by traditional thermal stability assessments. In this webinar, we will introduce a method for conducting stability tests using Uncle that is simple, requires only a small amount of sample, and can be performed at an early stage of development.

Creating perfect lipid nanoparticles (LNPs) requires technology. Testing flow rates and formulations one by one to find the appropriate size of LNPs is time-consuming and wastes valuable payload. Additionally, scaling up often requires new workflows, and there are always such challenges in new gene therapy research. Nunchuck is a groundbreaking platform that combines two critical steps necessary for producing LNPs of optimal size: Total Flow Rate (TFR) screening and LNP formulation exploration. It can screen eight types of TFRs in just 10 minutes, quickly finding the sweet spot and allowing immediate production of LNPs with capacities ranging from 0.5 to 200 mL. Moreover, the produced LNPs can be quickly evaluated for physical properties, such as payload measurement, using Stunner. This webinar will introduce how to conduct TFR screening suitable for the purpose of creating size-tunable, high-quality RNA-LNPs and how to scale up. We will also demonstrate how to evaluate the produced LNPs with Stunner.

Our company will be exhibiting at the 29th Annual Meeting of the Japanese Society of Gene and Cell Therapy, which will be held from September 11 (Monday) to September 13 (Wednesday), 2023.

The production, infectivity, Full/Empty ratio, and optimization of introduced genes for AAV take a lot of time. Additionally, during the formulation screening stage, many conditions need to be examined, such as different pH levels, salt concentrations, or additives. Our Unagi enables rapid and quantitative buffer exchange and concentration by applying pressure to the sample solution on a dialysis membrane, allowing for the simultaneous examination of numerous formulation conditions for AAV samples. Furthermore, Stunner can accurately assess the potency, Full/Empty ratio, and aggregation evaluation of AAV by simultaneously measuring UV/Vis and DLS in a high-throughput manner. In this webinar, we will explain how our Stunner and Unagi can facilitate accurate and rapid formulation studies and physical property evaluations of AAV samples.

Lipid nanoparticles (LNPs) are currently one of the most notable delivery systems used in mRNA vaccines, gene therapy, cancer treatment, and more. However, their development requires a complex process involving formulation screening, control of size and quality, removal of organic solvents, and characterization, which demands significant effort and time. In this webinar, we will introduce methods to enhance the production of perfectly sized LNPs, characterization of size and quality, buffer exchange and sample concentration, and stability analysis techniques at each step of the development process workflow.

Topic: In recent years, viruses have been widely used as modalities for gene therapy and vaccines, and research and development have been advancing. Adenoviruses are one of the representative viruses, but traditional evaluation methods are diverse and require a lot of time and effort. For example, obtaining quick answers regarding the capsid titer, Full/Empty ratio, and the presence of aggregation is a significant challenge. The UV/Vis absorbance at 260nm (A260) is considered the fastest method to confirm the titer of adenoviruses, but it requires denaturing the virus, resulting in an assay time of about 30 minutes. Additionally, the results of A260 can be inhibited by contamination from proteins, DNA, and various other substances. Furthermore, titer measurement methods like qPCR are not only time-consuming and labor-intensive but also consume a large amount of samples, making them unsuitable for rapid checks. Seminar Overview: In this seminar, we will explain how Stunner can quickly and accurately solve these challenges as a one-stop solution. We will also look at the application of adenovirus vector sample QC and the evaluation of various types of adenoviruses.

Topic: The development of biopharmaceuticals is becoming mainstream, but many challenges remain due to their complex structures and properties compared to small molecule drugs. For example, long-term stability testing of proteins in biopharmaceuticals is generally conducted in the later stages of biopharmaceutical development. This is because it requires a large amount of samples and time, making it unsuitable for early candidate drug screening. However, this approach carries the risk that issues with candidate drugs may only be discovered in the later stages of development. Additionally, controlling the viscosity of formulations is also an important development requirement, yet obtaining viscosity data can take too much time. Traditional methods require a large number of samples and can only measure one sample at a time. Even if there is a technology that can measure with just a few µL of sample, it still requires significant maintenance and time for tasks such as clog removal and cleaning. Webinar Overview: In this webinar, we will tackle these challenges in biopharmaceutical development and introduce methods for conducting isothermal stability testing in the early stages of development, as well as a technique for simultaneously measuring the viscosity of multiple samples in just a few minutes without the need for cleaning.

ADC (antibody-drug conjugate) is a biopharmaceutical that is attracting attention due to its pharmacological activity and the excellent specificity of antibodies. However, the characterization of ADCs is very challenging due to the rarity of samples and their tendency to aggregate. In this webinar, we will explain how to obtain important information such as the concentration, labeling, stability, and viscosity of mAbs and their conjugates from just a few microliters of samples, along with actual data to demonstrate the evaluation of ADC characteristics.

Challenge: Monitoring the titer, structural stability, and non-viral contaminants of lentiviruses during production is crucial for generating high-yield and high-purity pharmaceuticals. However, traditional methods such as ELISA and qPCR require sample purification and cannot perform structural analysis of the virus, making it very difficult to obtain accurate viral titers that are not affected by fragmented viral particles or contaminants. Solution: Unchained Labs' new product, Leprechaun, is a platform that provides critical information about crude or purified lentivirus samples. Leprechaun measures particle size to separate individual lentiviruses from aggregates and uses fluorescent antibodies to check for the presence of VSVG, capsid, soluble p24, and contaminants from extracellular vesicles (EVs). By using Leprechaun, it is possible to monitor titer and purity throughout the entire workflow of lentivirus research and development. In this webinar, we will explain how Leprechaun reveals the truths about your lentivirus that you have never known before.

In the evaluation of AAV characteristics, there is always a demand for rapid responses regarding measurement criteria such as capsid titer, genome titer, Empty/Full ratio, aggregation, total protein amount, and DNA amount. By combining this data, we can understand what is happening during sample and process development. However, since there are many characterization analysis methods available, the key to success lies in how to select appropriate analytical tools and how much data can be interpreted from rare samples. In this webinar, we will explain how our Stunner technology can assist in rapid sample QC, optimization of downstream purification chromatography, and improvement of workflows for other common analytical assays. We will present case studies from actual paper data demonstrating how Stunner accelerates AAV characterization and saves both samples and time.

In conventional protein quantification methods, one had to choose between high precision and high throughput. Plate-based UV/Vis measurements can provide instant readings, but their accuracy and precision are not very high. On the other hand, other measurement methods can achieve high precision, but they are time-consuming. Using our Lunatic for protein quantification offers superior precision, accuracy, and throughput compared to other methods, allowing for the measurement of 96 samples in 10 minutes with an accuracy within 2%. Additionally, Lunatic requires only 2μL per sample, making it very efficient. In this webinar, you will see data on the precision, reproducibility, and throughput of protein quantification using Lunatic. Even tricky samples that do not perform well with other UV/Vis readers can be analyzed without issues, as Lunatic's Unmix technology can identify contamination. Furthermore, we will also explain how to perform QC checks with the addition of DLS (Dynamic Light Scattering) technology.
