    摘要: Polypeptides that are cleared from the kidney and do not contain in their original form a Fc region of an IgG are altered so as to comprise a salvage receptor binding epitope of an Fc region of an IgG and thereby have increased circulatory half-life. Methods are described herein which utilize these polypeptides in treating disorders involving the LFA-1 receptor. In one of the described methods of treatment, the polypeptide includes the amino acid sequence PKNSSMISNTP (SEQ ID NO:3) and may also include the sequence selected from the group consisting of HQNLSDGK (SEQ ID NO: 1), HQNISDGK (SEQ ID NO:2), HQSLGTQ (SEQ ID NO:11) and VISSHLGQ (SEQ ID NO:31).

    摘要: A tissue plasminogen activator (t-PA) variant is prepared that has an amino acid deletion at positions 466 to 470 of the corresponding wild-type t-PA. This alteration renders the variant fibrin (and plasma clot) specific as compared to the corresponding wild-type t-PA. DNA sequences can be prepared that encode the variant, as well as expression vectors incorporating the DNA sequences, and host cells transformed with the expression vectors. The variant may be used in a pharmaceutical preparation to treat a vascular disease or condition or to prevent fibrin deposition or adhesin formation or reformation in mammals.

    摘要: The invention relates to a method of preparing heteromultimeric polypeptides such as bispecific antibodies, bispecific immunoadhesins, heteromultimers and antibody-immunoadhesin chimeras. Generally, the method involves introducing a protuberance at the interface of a first polypeptide and a corresponding cavity in the interface of a second polypeptide, such that the protuberance can be positioned in the cavity so as to promote heteromultimer formation and hinder homomultimer formation. The protuberance and cavity can be made by synthetic means such as altering the nucleic acid encoding the polypeptides or by peptide synthesis.
