摘要:
The invention relates to albumin fusion proteins comprising an albumin fusion partner and a protease inhibitor fusion partner which may be a Kunitz domain protease inhibitor capable of inhibiting a serine protease, including neutrophil elastase, kallikrein, and plasm The fusion proteins exhibit extended shelf life and/or extended therapeutic activity in solution. The invention encompasses therapeutic albumin fusion proteins, compositions, pharmaceutical compositions, formulations and kits comprising the albumin fusion proteins, a well as nucleic acid molecules encoding the albumin fusion proteins, vectors comprising these nucleic acids, host cells transformed w these nucleic acids and vectors, and methods of making the encoded proteins using the nucleic acids, vectors and/or host cells. The invention also relates to compositions and methods for inhibiting neutrophil elastase, kallikrein, and plasmin, and to compositions an methods for treating cystic fibrosis and cancer.
摘要:
Novel enterokinase cleavage sequences are provided. Also disclosed are methods for the rapid isolation of a protein of interest present in a fusion protein construct including a novel enterokinase cleavage sequence of the present invention and a ligand recognition sequence for capturing the fusion construct on a solid substrate. Preferred embodiments of the present invention show rates of cleavage up to thirty times that of the known enterokinase cleavage substrate (Asp)4-Lys-Ile.
摘要:
Novel small proteins which bind elastase or cathepsin G have been identified. These are useful as inhibitors of excessive elastase or cathepsin G activity in patients.
摘要:
The invention features apparati and methods for washing magnetically responsive particles such as paramagnetic beads. One exemplary apparatus includes a flow chamber having an inlet and an outlet; and at least a first magnetic field inducer. The apparatus is configured such that a first magnetic field can be selectively applied in the flow chamber. The apparatus can also apply a flow of fluid to the chamber in coordination with the selective application of the magnetic field.
摘要:
This invention relates to novel proteins that inhibit human neutrophil elastase (hNE). A large fraction of the sequence of each of these proteins is identical to a known human protein which has very little or no inhibitory activity with respect to hNE.
摘要:
The present invention provides binding moieties for CEA, which have a variety of uses wherever detecting, isolating or localizing CEA, and particularly CEA as opposed to cross-reactive antigens such as NCA, is advantageous. Particularly disclosed are synthetic, isolated polypeptides capable of binding CEA, which is overexpressed in adenocarcinomas of endodermally derived digestive system epithelia and fetal colon. Such polypeptides and disclosed derivatives are useful, e.g., as imaging agents for CEA-expressing tumors.
