  • Patent number: 11014986
    Abstract: Crystals of pembrolizumab and structurally similar anti-PD-1 monoclonal antibodies are provided, as well as methods of producing such crystals, and uses of compositions comprising such antibody crystals, e.g. in treatment of cancers. The present invention satisfies these needs and more by providing pembrolizumab crystals and a method producing pembrolizumab crystals. One embodiment of the method of the invention produces crystals suitable for X-ray diffraction, and the inventors herein used such crystals to solve the three-dimensional structure of pembrolizumab to 2.3 A resolution.

  • Patent number: 10500368
    Abstract: A device or arrangement for a carpule for a dental syringe permits the harpoon on the distal end of the plunger rod to engage the rubber or rubber-like plug or piston of the carpule, but blocks the piston from being pulled out the open proximal end of the tubular glass body of the carpule. A preferred version has an apertured cap that fits onto the proximal end of the carpule, a retaining neck ring that fits onto the penetrable seal at the proximal end of the carpule, and a bar connecting them. The bar also serves as a grip to assist in handling the carpule.

  • Publication number: 20150307606
    Abstract: Methods for preparing lyophilized pellets of antibodies that specifically bind to human IL-23 are described. The pellets have a substantially spherical shape and are prepared by freezing droplets of a liquid composition of a desired biological material on a flat, solid surface, in particular, a surface that does not have any cavities, followed by lyophilizing the frozen droplets. These methods are useful for preparing lyophilized pellets having a high concentration of anti-IL-23 antibody, and which have a faster reconstitution time than lyophilized powder cakes prepared in vials. Also provided are improved formulations for use in preparing lyophilized forms of antibodies that specifically bind to human IL-23.
