  • Patent number: 7482135
    Abstract: A method for determining whether a urine sample has been obtained from a subject suffering from a kidney disorder involving kidney damage. The method is based on determining the level of a proteolytic enzyme in urine from the subject. Sample and optionally comparing this level with a reference value. The proteolytic enzyme preferably is a matrix metalloproteases, in particular MMP-2 or MMP-9. The method is particularly suitable for subjects with a condition or disorder that is associated with an increased risk of kidney disorders, such as diabetes. The method may adavnatageously be applied for early detection of kidney damage, in particular when the subject does not yet show any sign of microalbuminuria. The method may also be applied to a subject undergoing dialysis for determining whether the subject is suffering from remodelling of the peritoneal membrane. Thus, the method is particularly suited for patients undergoing continuous ambulatory peritoneal dialysis.

  • Patent number: 6123938
    Abstract: The present invention is based on the purification and sequencing of isozymes of plasma hyaluronidase (pHAse) found in urine. Specifically, urine contains two hyaluronidases (HAses): 1) a 57 kDa HAse that is apparently the same as the 57 kDa HAse found in plasma; and 2) a 45 kDa HAse, which is found in urine but not plasma. The smaller urine isozyme is composed of two disulfide-linked polypeptides produced by endoproteolytic cleavage of the 57 kDa isoform. The present invention thus features a urinary hyaluronidase (uHAse) polypeptide and nucleotide sequences encoding a Chain A polypeptide and a Chain B polypeptide, the two polypeptides of which uHAse is composed. In a particular aspect, the uHAse is a human uHAse (huHAse), preferably a huHAse composed of the Chain A and B polypeptides having SEQ ID NOS: 2 and 4, respectively. In related aspects the invention features polynucleotide sequence encoding Chain A and Chain B polypeptides, preferably having the sequences of SEQ ID NOS: 1 and 3, respectively.

  • Patent number: 5359031
    Abstract: The present invention involves a method for detecting bladder cancer in a subject. The method preferably comprises first collecting a urine sample from the subject. The presence of a proteinaceous substance having a molecular weight of about 180 kDa according to its relative electrophoretic migration rate through detergent-containing polyacrylamide gel is then measured. This substance reversibly binds concanavalin A and is complexed with gamma globulin while in the urine. The gamma globulin complex binds to Staphlococcal protein A. Said proteinaceous substance, when present in detectable amount, is an indicator of bladder cancer.

  • Patent number: 4667016
    Abstract: Chromatographic procedures are individually and jointly applied to the rapid and efficient isolation of biologically active proteins and especially glycoproteins such as recombinant erythropoietin present in the medium of growth of genetically transformed mammalian host cells. Illustratively, recombinant EPO is isolated from culture fluids by reverse phase chromatography employing a C.sub.4 or C.sub.6 column and elution with ethanol. Recombinant erythropoietin may also be purified by anion exchange chromatography employing, e.g., a DEAE resin, with preliminary selective elution of contaminant materials having a lower pKa than erythropoietin from the resin under conditions mitigating against acid activated protease degradation. Practiced serially, the two chromatographic procedures allow for high yields of biologically active recombinant erythropoietin from mammalian cell culture media.
