摘要:
Growth hormone participates in the regulation of normal growth and development processes. The binding affinity of growth hormone for its target receptors is dependent upon the interaction of site 1 and site 2 domains of growth hormone with the target receptor. Embodiments of the present invention include site 1 variants of human growth hormone which bind to target receptors with a different affinity than that of the native hormone. Embodiments of the invention further include components for the production of isolated human growth hormone variants using a host cell/vector expression system.
摘要:
Antibodies are engineered by replacing one or more amino acids of a parent antibody with non cross-linked, highly reactive cysteine amino acids. Antibody fragments may also be engineered with one or more cysteine amino acids to form cysteine engineered antibody fragments (ThioFab). Methods of design, preparation, screening, and selection of the cysteine engineered antibodies are provided. Cysteine engineered antibodies (Ab), optionally with an albumin-binding peptide (ABP) sequence, are conjugated with one or more drug moieties (D) through a linker (L) to form cysteine engineered antibody-drug conjugates having Formula I: Ab-(L-D)p I where p is 1 to 4. Diagnostic and therapeutic uses for cysteine engineered antibody drug compounds and compositions are disclosed.

摘要:
Humanized and variant anti-VEGF antibodies and various uses therefor are disclosed. The anti-VEGF antibodies have strong binding affinities for VEGF; inhibit VEGF-induced proliferation of endothelial cells in vitro; and inhibit tumor growth in vivo.
摘要:
Peptide ligands having affinity for serum albumin are useful for tumor targeting. Conjugate molecules comprising a serum albumin binding peptide fused to a biologically active molecule demonstrate modified pharmacokinetic properties as compared with the biologically active molecule alone, including tissue (e.g., tumor) uptake, infiltration, and diffusion.
摘要:
Peptides are provided that antagonize the interaction of IGF-1 with its binding proteins, insulin receptor, and IGF receptor. These IGF antagonist peptides are useful in treating disorders involving IGF-1 as a causative agent, such as, for example, various cancers.
摘要:
IGF-I and insulin variants are provided that selectively bind to IGFBP-1 or IGFBP-3. These agonist variants are useful, for example, to improve the half-lives of IGF-I and insulin, respectively.

摘要:
Human growth hormone variants are disclosed wherein the lysine at position 41 and/or the leucine at position 45 of native human growth hormone, numbered from the mature N-terminus of native human growth hormone, has been replaced with another amino acid. Also claimed are combination variants that have a higher binding affinity to the growth hormone receptor than wild-type human growth hormone.
摘要:
The invention relates to anti-Factor D antibodies, their nucleic acid and amino acid sequences, the cells and vectors that harbor these antibodies and their production and their use in the preparation of compositions and medicaments for treatment of diseases and disorders associated with excessive or uncontrolled complement activation. These antibodies are useful for diagnostics, prophylaxis and treatment of disease.
