keratan-sulfate endo-1,4-beta-galactosidase

02/01/1995 - "Endo-beta-galactosidase digestion resulted in the elimination of these antigens not only in papillary carcinomas but also in other neoplasms.(ABSTRACT TRUNCATED AT 250 WORDS)"
08/01/1995 - "Blood-group-related antigens expressed in papillary carcinomas and other types of neoplasm of the human thyroid glands have been shown to be carried by poly-N-acetyllactosamines containing a linear domain susceptible to endo-beta-galactosidase digestion. "
08/01/1995 - "To make clear more precisely the backbone poly-N-acetyllactosamine structures, labelled lectins specific to different types of these structures and specific to core structures with beta 1-6GlcNAc branching of N- and O-linked glycoproteins were employed in conjunction with prior endo-beta-galactosidase digestion on formalin-fixed, paraffin-embedded neoplasms of the human thyroid glands. "
03/01/1986 - "(streptomyces hyaluronidase, testicular hyaluronidase, chondroitinase ABC, chondroitinase AC, keratanase, heparinase, heparitinase.) According to these experiments, high-grade, and high-stage tumors contained large amounts of sulfated mucopolysaccharides. "
09/01/1996 - "Blood group ABH antigens, which are simultaneously expressed together with keratan sulphate epitope in cancer cells, were eliminated by digestion with endo-beta-galactosidase and N-glycosidase F, but were resistant to keratanase and keratanase II treatment. "

08/01/1995 - "Prior digestion with endo-beta-galactosidase completely eliminated or markedly reduced the reactivity with PWM and LEA in papillary carcinomas. "
09/01/1996 - "Along with the endo-beta-galactosidase-GSA-II labelling procedure, labelling with 5-D-4 may be a useful diagnostic means for distinguishing papillary carcinoma from other types of thyroid neoplasms."
02/01/1995 - "Endo-beta-galactosidase digestion resulted in the elimination of these antigens not only in papillary carcinomas but also in other neoplasms.(ABSTRACT TRUNCATED AT 250 WORDS)"
09/01/1996 - "The reactivity of 5-D-4 with papillary carcinomas was markedly reduced or abolished by prior digestion with endo-beta-galactosidase, keratanase II, or N-glycosidase F. "
01/01/1996 - "Staining with lectins specific to poly-N-acetyllactosamine in combination with endo-beta-galactosidase digestion demonstrated that poly-N-acetyllactosaminyl structures ubiquitously and consistently produced in thyroid papillary carcinomas are highly heterogeneous in their chain length and branching status and quite different from those produced in other thyroid neoplasms. "

01/01/1984 - "Since the molecular basis of this membrane abnormality has not yet been defined, membrane glycoproteins of HEMPAS erythrocytes were analysed by cell surface labelling and endo-beta-galactosidase digestion in this study. "
12/15/1986 - "Presently, we have isolated polylactosaminyl lipids from HEMPAS blood cells and analyzed their structures by fast atom bombardment-mass spectrometry (FAB-MS), methylation analysis, endo-beta-galactosidase digestion. "
01/01/1984 - "HEMPAS glycan was characterized by micelle formation, a monomer molecular weight of 4000, susceptibility to endo-beta-galactosidase and resistance to protease. "

04/11/2003 - "The results indicate that endo-beta-galactosidase-sensitive and mAb FH6-reactive carbohydrate chains are generated under the control of expression levels of FUT6 and involved in the adhesion of colon carcinoma cells to liver sections."
09/15/2000 - "Involvement of cell surface glycans in adhesion of human colon carcinoma cells to liver tissue in a frozen section assay: role of endo-beta-galactosidase-sensitive structures."
01/01/2001 - "Our observations suggest that endo-beta-galactosidase-sensitive carbohydrate chains containing an epitope recognized by mAb FH6 play an important role in the adhesion of human colon carcinoma cells to human liver sections. "
01/01/2001 - "This adhesion was not blocked by anti-E-selectin monoclonal antibodies, but pretreatment of the carcinoma cells with endo-beta-galactosidase significantly reduced both cell surface binding of mAb FH6 and the ability of the cells to adhere to liver sections. "
09/01/1996 - "Although keratanase digestion had no effect on 5-D-4 labelling, it revealed the binding sites of Griffonia simplicifolia agglutinin II (GSA-II), which recognizes terminal N-acetylglucosamine in a limited number of carcinoma cells from some individuals. "

01/01/1991 - "Thirty female rabbits were immunized, 5 per group, with 100 micrograms each of either 1) SIZP, solubilized isolated zonae pellucidae; 2) ZP3, a purified porcine zona preparation containing the two principle glycoproteins, ZP3 alpha and ZP3 beta, endo-beta-galactosidase-digested ZP3 glycoproteins (approximately 30% deglycosylated) termed 3) ZP3 alpha/EBGD and 4) ZP3 beta/EBGD; and chemically deglycosylated ZP3 alpha and ZP3 beta (greater than or equal to 92% deglycosylated), termed 5) ZP3 alpha/DG and 6) ZP3 beta/DG. "
06/01/2001 - "We have previously reported that apparent relative molecular masses of bovine zona glycoproteins on SDS/PAGE under nonreducing conditions after removal of poly N-acetyllactosamine at the nonreducing portion of sugar chains with endo-beta-galactosidase are 72 000, 58 000 and 45 000 [Noguchi, S., Yonezawa, N., Katsumata, T., Hashizume, K.,Kuwayama, M., Hamano, S., Watanabe, S. "
10/01/1995 - "The sperm receptor activity of pig zona pellucida has been previously shown to exist in one of the components, pig zona protein 3 alpha (PZP3 alpha), that can be purified after the removal of sialylated and/or sulfated N-acetylpoly(lactosamine) by digestion with endo-beta-galactosidase. "
01/01/1990 - "These results together with those of the analyses of endo-beta-galactosidase digests showed that the charge heterogeneity of the porcine zona proteins is due mainly to differences in the amount of sulfated lactosamine, which is predominantly distributed in the non-reducing regions of the sugar chains."
