  • Patent number: 12270631
    Abstract: A personal security device (100), comprising: a base body (110) forming a chamber (110), wherein a first opening (140) of the chamber (110) is sealed by a film (190); a safety liquid provided in the chamber (110); and a cover body (200) movably attached to the base body (100). Wherein the cover body (200) comprises a first surrounding portion (210) circumscribing a first portion (180) of the base body (100), and a top portion (220) arranged above the film (190). Wherein the top portion (220) comprises a cutting device (230a, 230b) facing the film (190), and a release opening (240) extending through the top portion (220). Wherein the cover body (200) is configured to be moved in relation to the base body (100) such that the cutting device (230a, 230b) perforates the film (190) when the cover body (200) is moved towards the film (190) thereby releasing the safety liquid through the release opening (240).

  • Publication number: 20110053225
    Abstract: The present invention relates to multifunctional protein production tags comprising at least 4, preferably 4-8 amino acids, for optimising expression of proteins and purification thereof by various multi-step processes including chromatographic or filtration, as well as batch unit operations. The tags include sequences of multiple defined purposes which are not generated in defined linear sequence regions related to one purpose but as integrated sequences often overlapping each other, i.e. the defined purposes are not discrete separate units on the tag but rather heterogeneously distributed in the tag. The invention also relates to an expression vector encoding the multipurpose tag and a method for protein purification, comprising expressing a protein in the expression vector and purifying the protein in several steps using functionalities of the multipurpose tag.

  • Publication number: 20100233783
    Abstract: Process for purifying a recombinant protein including one or a few procedural steps only. The process combines the step of lysis of the host cell, with the purification of the protein of interest, allowing for a rapid and much more efficient process of purification. The conditions used during the purification process are those of a high temperature and a low pH, allowing for thermostable and acid-resistant recombinant proteins to be isolated from a suspension. The invention also relates to purifying recombinant proteins which are fusion proteins, wherein one part of the protein may be selected from an enamel matrix protein, such as amelogenin.

  • Patent number: 5959187
    Abstract: The present invention relates to genetic-engineering of plants for enhanced oxygen assimilation and utilization. More particularly, this invention relates to producing transgenic plants engineered to express oxygen-binding proteins such as, for example, hemoglobin, myoglobin, and hemoproteins. The engineered plants of the invention achieve quicker germination, are faster growing or maturing crops, produce higher crop yields, and/or contain higher levels of desired plant metabolites, particularly alkaloids.
