Abstract: This invention relates to Factor VIII muteins that are covalently bound, at a predefined site that is not an N-terminal amine, to one or more biocompatible polymers such as polyethylene glycol. The mutein conjugates retain FVIII procoagulant activity and have improved pharmacokinetic properties.

Abstract: Disclosed is both a method for preparing a plasminogen and a method for preparing a reversibly inactive acidified plasmin by activating the plasminogen. The prepared plasminogen is typically purified from a fraction obtained in the separation of immunoglobulin from Fraction II+III chromatographic process and eluted at a low pH. The prepared plasmin is isolated and stored with a low pH-buffering capacity agent to provide a substantially stable formulation. The reversibly inactive acidified plasmin may be used in the administration of a thrombolytic therapy.

Abstract: This invention relates to Factor VIII muteins that are covalently bound, at one or more predefined sites that are not an N-terminal amine, to one or more biocompatible polymers such as polyethylene glycol. The mutein conjugates retain FVIII procoagulant activity, are capable of correcting human factor VIII deficiencies and have improved pharmacokinetic properties.

Abstract: A biopsy sampling system and method for aspirating bone marrow and bone cores from a patient with minimal or no perceived pain to the patient. The system includes a bone aspiration needle assembly having a handle and an electrically conductive needle shaft and an electrical nerve stimulator (ENS) which supplies a current of adjustable intensity to the needle shaft. Thus, when the aspirating needle is inserted into the bone marrow cavity of the patient, the stimulator is activated to anesthetize the nerves in the vicinity of the aspiration permitting the extraction to commence with little or no increased pain to the patient. A nonconducting insulating shaft is also disclosed to be placed on the needle shaft in order direct the ENS current to the area of the shaft that can most efficiently anesthetize the pain conducting nerves, i.e. to the tip of the needle shaft.
