  • Patent number: 12655177
    Abstract: The present invention provides an improved manufacturing method for the production of bispecific antibody products, which comprise at least two binding domains. The process comprises at least the method comprising a step of refolding the construct, wherein one or more of the domains comprise a disulfide bond, and wherein the construct is contacted with a refolding buffer to refold the construct to its native form, the buffer comprising (i) a redox and/or oxidizing agent having a concentration of at least 0.1 mM and (ii) a chaotropic agent having a concentration >1 M, and wherein the pH of the refolding buffer corresponds to +/?4.5 of the pI value of the first domain or +/?4.0 of the pI value of the entire construct.

  • Patent number: 12649788
    Abstract: The present invention relates to antigen binding proteins, such as monoclonal antibodies, that specifically bind to and activate human triggering receptor expressed on myeloid cells-2 (TREM2) and pharmaceutical compositions comprising such antigen binding proteins. The agonist antigen binding proteins (e.g. antibodies) of the invention are capable of activating TREM2/DAP12 signaling in myeloid cells in the absence of Fc-mediated cross-linking of the antigen binding proteins. Methods of treating or preventing conditions associated with TREM2 loss of function, such as Alzheimer's disease and multiple sclerosis, using the antigen binding proteins are also described.

  • Patent number: 12616795
    Abstract: A drug delivery device and a method of using the drug delivery device may include a housing having an opening and a drug storage container including a delivery member. The drug storage container may be coupled with the housing such as to substantially prevent relative movement between the drug storage container and the housing. A guard may be positioned adjacent to the opening and operably coupled with a plunger biasing member such that a relative movement between the guard and the housing permits release of the plunger biasing member to urge a plunger in to expel a drug from the drug storage container. A lock component may be configured to resist the relative movement between the guard and the housing until the lock component is released by a user force, whereafter the user force drives the housing and the drug storage container toward an injection site.

  • Patent number: 12620075
    Abstract: In a method for enhancing accuracy and efficiency in automated visual inspection of vessels, a vessel containing a sample is oriented such that a line scan camera has a profile view of an edge of a stopper of the vessel. A plurality of images of the edge of the stopper is captured by the first line scan camera while spinning the vessel, where each image of the plurality of images corresponds to a different rotational position of the vessel. A two-dimensional image of the edge of the stopper is generated based on at least the plurality of images, and pixels of the two-dimensional image are processed, by one or more processors executing an inference model that includes a trained neural network, to generate output data indicative of a likelihood that the sample is defective.
