examples of inter- and intramolecular direct co-functioning of lectins and enzymes are summarized. the data indicate importance of lectin-enzyme relationships in molecular and clinical microbiology and medical biotechnology. lectin-enzyme relationships have extended prospects in medicine and biotechnology.

To evaluate the relative mobilities of cell surface glycoconjugates during myogenesis we have studied the redistribution of fluorescein-conjugated plant lectins on L6 rat myogenic cells. Previous experiments had demonstrated that the receptors for the lectins soybean agglutinin (SBA), wheat germ agglutinin, concanavalin A and Lens culinaris agglutinin all were relatively uniformly distributed o...

one of the important parts of innate immunity is complement system that occurs in three different ways; the classic, the alternative and the lectin pathway. the four pattern recognition molecules that have been identified till now are mannose binding lectin (mbl), a component of lectin pathway, and three ficolins (ficolin1,-2 and -3) which compound to the carbohydrates of the cell surface. mbl ...

during early neurogenesis, the floor plate plays an essential role(s) in the differentiation of the ventral portion of neural tube. in this study, we detected the specific distribution of unique glycoconjugate during the floor plate differentiation. formalin fixed paraffin sections of balb/c mice (10-14 embryonic days) were processed for histochemical studies using horseradish peroxidase-labell...

glycoconjugates and their programmed changes during the course of development in the cell-surface as well as in the extracellular matrix, are known to affect cell differentiation, cellular interaction and other developmental phenomena during embryogenesis. the purpose of this study was to localize n-acetylgalactosamin as well as fucose-containing glycoconjugates in situ during thymus developmen...

objective(s) the aim of this study was to investigate glycoconjugates distribution patterns as well as their changes during the course of pituitary portal vasculogenesis and angiogenesis. materials and methods formalin fixed paraffin sections of 10 to 20 days of sprague dawly rat fetuses were processed for histochemical studies using four different horseradish peroxidase (hrp) conjugated lectin...

results in this study, 45 (13.4 %) urine samples were positive for candida species (17 males and 28 females). the most common isolated yeast was candida albicans (34%), followed by c. glabrata (32.1%), c. tropicalis (9.4%), other candida species (22.6%), and rhodotorula species (1.9%). the mean serum levels of mbl were 0.85 ± 0.01 ng/ml and 1.02 ± 0.03 ng/ml among candiduric patients and contro...

background: ‍‍cryopreservation has some detrimental impacts on sperms surface molecules. modification of the sperm surface molecules can affect on fertility rate. one of the important surface molecules are glycoconjugates. objective: the objective of this study was to evaluate the changes of content of the glycocalyx after standard cryopreservation procedure. materials and methods: forty five h...

The generalization of p-frame in Banach spaces is considered in this paper. The concepts of an $tilde{X}$-frame and a system conjugate to $tilde{X}$-frame were introduced. Analogues of the results on the existence of conjugate system were obtained. The stability of $tilde{X}$-frame having a conjugate system is studied.

Polyclonal antisera were raised against a peptide containing the cysteine residue required for carbohydrate binding activity in the lima bean lectin. The antisera were tested for cross-reactivity with (a) synthetic peptide analogs to the essential cysteine containing peptide, (b) proteolytic digests of related lectins, (c) native lectins. The antisera were specifically inhibited from binding to...
