摘要:
Cells with forced expression of swine Toll-like receptor 9 (TLR9) are prepared by cloning a TLR9 gene from swine intestinal Peyer's patches. Functional analysis on CpG DNAs using the above cells revealed that swine TLR9 shows a higher recognition ability for a human CpG DNA motif (CpG2006) than for a mouse-specific CpG DNA motif (CpG1826). When the mRNA expression levels in various tissues are compared by the real-time PCR method, it is found out that the mRNA is expressed in Peyer's patches and mesenteric lymph nodes, which play important roles in the intestinal tract immune system, at a level thrice as much as in spleen or more. Thus, the cells that are forced to express an intestinal tract tissue-expressed TLR (for example, TLR9) can be used to identify samples capable of activating the intestinal tract immune system.

The invention provides methods and compositions for identifying colon cancers in an individual. In one embodiment of the invention, a colon adenocarcinoma-associated protein may be detected in a tissue or body fluid sample of an individual, to provide an indication of the presence of an adenocarcinoma of the colon in the individual. The target adenocarcinoma-associated protein, may be detected, e.g., by reacting the sample with a labeled binding moiety, such as a labeled antibody, capable of specifically binding the protein. In another embodiment, the protein may be detected by isolating one or more colon adenocarcinoma-associated proteins from the sample, separating the proteins by two dimensional gel electrophoresis, and comparing the gel electrophoresis pattern with a standard. The invention provides a wide range of assay methods and compositions which may be used for detecting colon tumors in an individual rapidly and reproducibly, optimally at early stages of the disease.

1. A PROCESS FOR THE SEPARATION OF SECRETIN AND CHOLECYSTOKININ-PANCREOZYMIN FROM A MIXTURE THEREOF, COMPRISING (A) CONTACTING THE MIXTURE IN AQUEOUS SOLUTION AT A PH RANGING FROM ABOUT 9 TO ABOUT 12, WITH AN ANIONEXCHANGE RESIN TO CAUSE SELECTIVE ADSORPTION OF CHOLECYSTOKININ-PANCREOZYMIN ON SAID RESIN AND RESERVING THE REMAINING AQUEOUS SOLUTION, (B) ELUTING THE CHLOECYSTOKININ-PANCREOZYMIN FROM SAID RESIN BY CONTACTING IT WITH AN AQUEOUS ELUTING MEDIUM AT PH LOWER THAN 9: AND (C9 RECOVERING THE CHOLECYSTOKININ-PANCREZYOIN FROM THE ELUATE OF STEP (B) AND RECOVERING THE SECRETIN FROM THE AQUEOUS SOLUTION OBTAINED FROM STEP 8A), WHICH SOLUTION CONTAINS THE SECRETION NOT ADSORBED BY SAID RESIN.
摘要:
METHOD FOR THE SELECTIVE SEPARATION AND RECOVERY OF POLYPETIDE SUBSTANCES (E.G. BACTERIAL AND FUNGAL EXOENZYMES, HEME PIGMENTS, POLYPEPTIDE HORMONES) FROM A BIOTIC FLUID (E.G. CULTURE BROTH, BLOOD SERUM, URINE, SAP, EXTRACTS OF DISINTERGRATED CELLS). INVOLVES CONTACTING THE BIOTIC FLUID WITH A MACRORETICULAR RESIN TO EFFECT ADSORPTION OF THE POLYPETIDE, WASHING THE RESIN WITH WATER OR SALT SOLUTION, AND THEN ELUTING THE POLYPETIDE WITH AN AQUEOUS SOLUTION OF AN IONIZING SUBSTANCE AND A MISCIBLE LOW MOLECUALR WEIGHT ORGANIC SOLVENT. THE MACRORETICULAR RESINS EMPLOYED MAY BE COPOLYMERS OF DIVINYLBENZENE WITH STYRENE AND ETHYLVINLYBENZENE OR COPOLYMERS OF TRIMETHYLOLPRPANE TRIMETHYLACRYLATE WITH TRIMETHYLOLPROPANE DIMETHACRYLATE.
