  • Patent number: 6063901
    Abstract: The present invention is directed to processes for isolating and identifying the nucleotide sequence of a gene for a novel macrophage receptor with collagenous structure, termed "MARCO". The new macrophage receptor with a collagenous domain binds gram positive and negative bacteria and acetylated LDL. Moreover, the invention relates to the nucleotide sequence for MARCO identified by the process of the invention and the isolated and purified polypeptide chain encoded by such a sequence.

  • Patent number: 5593900
    Abstract: The present invention provides for a method for preparing antibodies that specifically detect the type IV collagen .alpha.5 chain that is defective in various basement membrane disorders such as in X chromosome-linked Alport's syndrome. The invention further provides for the use of such antibodies to detect the .alpha.5(IV) collagen chain in solutions and other human tissue specimens using immunological methods comprised of antibodies specific for said protein. Along this line, the invention relates to the use of the specific antibodies to examine the presence or absence of the .alpha.5(IV) collagen chain in the tissues, e.g. skin or kidneys, etc. of patients with renal failure, possibly due to Alport's syndrome. In addition, a further object of the present invention is to provide compositions, comprising both labeled and unlabeled peptides containing sequences from the .alpha.

  • Patent number: 5114840
    Abstract: The present invention provides for a method for isolating and partially characterizing the nucleotide sequence for a novel polypeptide chain of human basement membrane (type IV) collagen, referred to as the .alpha.5(IV) polypeptide chain. The invention provides for the use of the identified nucleotide sequence (or DNA fragments thereof) to detect mutations in individual genes specific for the .alpha.5(IV) chain which can, directly or indirectly, produce several human diseases. Moreover, the invention also relates to procedures for determining genetic or acquired disorders of basement membranes using the identified nucleotide sequence (or DNA fragments thereof) of the .alpha.5(IV) polypeptide chain, probes specific to DNA fragments of said nucleotide sequence,or antibodies to the nucleotide sequence or DNA parts thereof.
