  • Patent number: 9187550
    Abstract: A lipid particle comprising an apolipoprotein, a phosphatidylcholine and a lipid, such as a phospholipid, fatty acid or steroid lipid. In one embodiment the lipid particle comprises only one apolipoprotein. In one embodiment the lipid particle is consisting of one apolipoprotein, a phospholipid, a lipid, and a detergent. In one embodiment the lipid is a second phosphatidylcholine, wherein the first phosphatidylcholine and the second phosphatidylcholine differ in one or two fatty acid residues or fatty acid residue derivatives which are esterified to the glycerol backbone of the phosphatidylcholine. In one embodiment the apolipoprotein is selected from an apolipoprotein that has the amino acid sequence selected from SEQ ID NO: 01, 02, 06, 66, and 67, or is a variant thereof that has at least 70% sequence identity with the selected sequence.

  • Patent number: 5973118
    Abstract: A polypeptide which has the activity of an inhibitor DE-3 from Erythrina caffra and which reversibly and selectively binds serine proteases from a protein mixture is obtainable by culturing prokaryotic or eukaryotic host cells which have been transformed or transfected with a nucleic acid that codes for the said polypeptide in a manner that allows the host cells to express the said polypeptide under suitable nutrient conditions and isolating the said polypeptide, wherein the polypeptide has an amino acid sequence which is functionally analogous to SEQ ID NO:2, has a partial region that is more than 85% homologous to the region of amino acids 39-139 of this sequence, has two disulfide bridges and begins N-terminally with SEQ ID NO:4 or with a SEQ ID NO:4 extended N-terminally by methionine and has a binding capacity for tissue plasminogen activators of 1.25 MU/ml and more and is particularly suitable for purifying plasminogen activators such as tissue plasminogen activators (t-PA and derivatives).

  • Patent number: 5958722
    Abstract: Process for purifying serine proteases from a protein mixture by binding the serine protease to an immobilized polypeptide with the activity of an inhibitor DE-3 from Erythrina caffra, removing unbound components from the protein mixture, detaching the serine protease from the inhibitor and separating the immobilized inhibitor from the soluble serine protease and isolating serine protease which is characterized in that a polypeptide is used as the polypeptide which is the product of a prokaryotic or eukaryotic expression of an exogenous nucleic acid. This inhibitor is distinguished by an improved specific activity and is particularly suitable for the purification of plasminogen activators such as tissue plasminogen activators (t-PA and derivatives).
