  • Patent number: 12247072
    Abstract: The present disclosure provides methods and compositions comprising IL-21 polypeptides, targeted cytokine construct that selectively activates target immune cells (e.g., CD8+ T cells) over other immune cell types. The cytokine of the present disclosure can further comprise mutations that alter its charge distribution to improve its half-life within the blood.

  • Publication number: 20250051704
    Abstract: The present invention discloses a multifunctional Petri dish with two sealing structures to ensure that the water in the medium will not evaporate during continuous culture, further affecting cultured living material growth and development. In addition to alcohol spray, the multifunctional Petri dish allows the application of acids, alkalis, alcohols, peroxides solution, or peroxides gas to immerse the multi-purpose Petri dish to remove bacteria or viruses. Various accessory devices can meet all requirements for a living culture of cells and tissues that the existing Petri dishes cannot provide. Using the dish cover operator and the dish container operator is essential to ensure that the researcher's hands will not directly touch the Petri dish in the sterile operating bench, thereby blocking all potential contamination of the medium and culture by foreign organisms.

  • Patent number: 11841027
    Abstract: A demand-based load balancing function may be provided by one or more drive controllers that takes advantage of the affinity laws to linearize the control of the variable of interest (e.g., flow, pressure, etc.). Each drive controller may be set up by the user simply inputting a few values into the drive controller. Based on the inputs, the drive controllers may interpolate control points using an assumed linear relationship between the variable to be controlled (e.g., pressure) and the current driven to the pump. Feedback data from the system may be used to continually update the drive controllers so as to potentially allow them to better balance power usage to each pump.
