Binding of lectins to “young” and “old” human erythrocytes
TLDR
It is thought that human erythrocyte aging is accompanied by elimination of some glycoconjugates which have affinity for six lectins, LPA, Con A, RCA-II, PHA-E, SBA and BPA, whereas no WGA receptor-containing glycconjugates are released from ery throat membranes. Expand
A Sialoglycopeptide liberated from Human Red Cells by Treatment with Trypsin
PREVIOUSLY1, it was shown that treatment of human red cells with crystalline trypsin in a low concentration resulted in destruction of the I agglutinogen on their cells and release of aExpand
MN blood-group active sialoglycopeptides released from human erythrocytes by pronase treatment.
Comparative study on the main membrane-surface sialoglycopeptides released from young and old human erythrocytes with trypsin.
TLDR
The amount of sialoglycopeptide mixture released from young (Y) erythrocytes by trypsin treatment was significantly larger than that from old (O) ones and the reactivities against the lectins of Limulus polyphemus and Phaseolus vulgaris were stronger in the Y-S GP than in the O-SGP. Expand
Purification and characterization of anti-N lectin from Vicia unijuga leaves.
TLDR
An anti-N lectin was extracted from Vicia unijuga leaves with phosphate-buffered saline and was not inhibited by any of mono- and di-saccharides, ABH-active glycoproteins, glycophorin AM and M-active sialoglycopeptide liberated from human M erythrocytes by treatment with Pronase or trypsin. Expand
Number and distribution density of ABH and MN antigen sites on young and old human erythrocyte surfaces.
TLDR
It is suggested from these and other observations that human erythrocyte aging is accompanied by elimination of a small amount of B and H antigens from cell membranes, while A, A1, M, N and Vicia graminea N antIGens are not released from cell membrane during in vivo aging. Expand
[Some chemical and serological properties of non-dialysable fractions of human seminal plasmas].
TLDR
Although WSF and WISF did not react with anti-M and -N sera respectively, both of the fractions reacted with the anti-N lectins of Vicia graminea and V. unijuga and also with Arachis hypogaea anti-T (Thomsen-Friedenreich) lectin. Expand
SOME PROPERTIES OF SIALOGLYCOPEPTIDES RELEASED FROM HUMAN ERYTHROCYTES BY TREATMENT WITH PROTEINASES
Some properties of sialoglycopeptides released from human erythrocytes by trypsin and pronase, were examined. It is suggested that the sialoglycopeptides possess a cation - exchange behavior.
[Separation of Thomsen-Friedenreich (T) antigen and N antigen precursor glycoproteins from perchloric acid-soluble fraction of cyst fluid of human ovarian clear cell carcinoma and their some chemical
TLDR
Reactivities against various hemagglutinins of these four fractions suggest that DEAE-Fr. Expand
