Abstract: Methods and compositions are provided for efficient production of human insulin-like growth factor. Synthetic IGF I and IGF II genes are joined to leader and processing signals which provide for expression and secretion of the gene product in yeast. Enhanced yields of the product may then be recovered from the nutrient medium. Yeast strains S. cerevisiae AB103 (pYIGF-I-10/1) and AB103 (pYIGF-II-10/1) were deposited at the American Type Culture Collection on Apr. 23, 1983 and granted Accession Nos. 20673 and 20674, respectively.

Abstract: Inhibitors, including antibodies, of IL8 binding to its receptors, that interact with the amino-terminal extracellular domain of the IL8 receptor and which compete with IL8 for receptor-binding, are disclosed. The inhibitors are useful modulators of IL8 receptor-mediated biological activity.

Abstract: Methods and compositions are provided for the production of a polypeptide which is immunologically cross-reactive with a naturally-occurring major outer membrane protein (MOMP) of Chlamydia trachomatis. A DNA construct including a replication system recognized by E. coli, and an MOMP gene under the transcriptional control of a .beta.-glactosidase promoter and terminator is provided. Recombinant phage .lambda.gtll/L2/33 was deposited at the American Type Culture Collection, 12301 Parklawn Drive, Rockville, Md. 20852, on Jan. 10, 1985 and granted accession no. 40157. L2 B9-F DNA was deposited at the American Type Culture Collection on Dec. 31, 1985, and granted accession No. 40217.

Abstract: Novel polypeptide compositions based on the amino acid sequence of tissue plasminogen activator (tPA) are provided having improved properties over natural tissue plasminogen activator. Particularly, enhanced specific activity, reduced response to inhibition by plasminogen activator inhibitor, fibrin stimulation of plasminogenolytic activity and/or enhanced affinity to fibrin surfaces are provided by modifying one or more loci by deletions or substitutions. One or both of the N- or C-termini may be modified.
