Abstract: Peptides that home, target, migrate to, are directed to, are retained by, or accumulate in and/or bind to the cartilage or kidney of a subject are disclosed. Pharmaceutical compositions and uses for peptides or peptide-active agent complexes comprising such peptides are also disclosed. Such compositions can be formulated for targeted delivery of an active agent to a target region, tissue, structure or cell in the cartilage. Targeted compositions of the disclosure can deliver peptide or peptide-active agent complexes to target regions, tissues, structures, or cells targeted by the peptide.

Abstract: Systematic chemical analysis of glycosphingolipid (GSL) fractions from large quantities of normal human neutrophils and HL60 cells failed to detect GSL's containing an SLex structure. Instead, the binding target of E-selectin was revealed to be a series of long-chain, unbranched polylactosamine GSL's with a terminally sialylated, internally polyfucosylated structure, called, “myeloglycan”.

Abstract: A series of long chain, unbranched polylactosamine glycosphingolipids with terminally sialylated, internally polyfucosylated structures binds selectins.

Abstract: A variety of compounds are provided which are useful as immunogens and as tumor markers. The present invention discloses methods relating to the detection of cancer. Extended forms of the lacto-series type 1 chain are shown to be present in various cancer tissues. The present invention also provides a cell line and the monoclonal antibody produced therefrom. Such an antibody has a number of uses, including in diagnostic or therapeutic methods.

Abstract: An unbranched polylactosamine comprising at least 6 monosaccharides and having terminal .alpha.2.fwdarw.3 sialylation and internal .alpha.1.fwdarw.3 fucosylation at various N-acetylglucosamine residues except for solely at the penultimate N-acetylglucosamine residue.

Abstract: The invention relates to antibodies that specifically bind a myelorollin comprising an unbranched polylactosamine comprising at least 10 monosaccharides and having terminal .alpha.2.fwdarw.3 sialylation and internal .alpha.1.fwdarw.3 fucosylation at various N-acetylglucosamine residues except the penultimate N-acetylglucosamine residue. The invention also relates to a method of using such antibodies to inhibit E-selectin-dependent rolling of a cell on another cell, wherein one of the cells expresses a myelorollin that binds the antibodies.
