Terminal alpha (1,3) galactosyl galactoside epitopes (alpha-gal) on membrane glycoproteins expressed by vascular endothelial cells represent the major xenoreactive antigens in pig to primate xenotransplantation. In other discordant xenotransplantation combinations, such as from guinea pig to rat,
A galactose-specific lectin has earlier been isolated from the seeds of Dolichos lablab in our laboratory by conventional protein purification methods. We now established conditions to bind the lectin on Sepharose-galactose gel in the presence of 1.5 M ammonium sulfate in Tris-buffered saline, pH
The mannose/glucose-binding Dolichos lablab lectin (designated DLL) has been purified from seeds of Dolichos lablab (hyacinth bean) to electrophoretic homogeneity by affinity chromatography on an ovalbumin-Sepharose 4B column. The purified lectin gave a single symmetric protein peak with an apparent
Ex vivo culture of hematopoietic stem cells is limited by the inability of cytokines to maintain primitive cells without inducing proliferation, differentiation, and subsequent loss of repopulating capacity. We identified recently in extracts of kidney bean and hyacinth bean a mannose-binding
The conformation of the lectins from Dolichos biflorus and Robinia pseudoacacia was studied by means of circular dichroism (CD). It was found that N-acetyl-D-galactosamine induced significant changes in the near-ultraviolet CD spectrum of Dolichos lectin but was ineffective with the lectin from
The structural properties of eight lectins (agglutinins) were studied by the circular dichroism (CD) probe. The lectin from Maclura pomifera (osage orange seed) exhibited in the far-ultraviolet spectral zone a positive CD band centered at 201 nm, whereas the other lectins had positive bands at
This paper reports a study on the hydroxylation of ferulic acid and tyrosine by field bean (Dolichos lablab) polyphenol oxidase, a reaction that does not take place without the addition of catechol. A lag period similar to the characteristic lag of tyrosinase activity was observed, the length of
A proteinase inhibitor resembling Bowman-Birk family inhibitors has been purified from the seeds of cultivar HA-3 of Dolichos lablab perpureus L. The protein was apparently homogeneous as judged by SDS-PAGE, PAGE, IEF, and immunodiffusion. The inhibitor had 12 mole% 1/2-cystine and a few aromatic
Seeds of Dolichos lablab var. lignosus (field beans) and variety typicus (lablab beans) contain glucose/mannose specific lectins that have been affinity purified and well characterised (Siva Kumar N., and Rajagopal Rao, D., J.Biosci., 1986, 10, 95-109, (1) Rajasekhar et al., (Biochem.Archives. 1997,
The circular dichroism (CD) spectra of lectins from Dolichos biflorus, Helix pomatia, Lotus tetragonolobus, Phaseolus vulgaris (erythroagglutinin), Pisum sativum, Sophora japonica, and Ulex europaeus I were analyzed, before and after the conformational transitions which were effected by sodium
Development of suitable selective marker for buffalo spermatogonial stem cells (SSCs), optimization of long-term IVC conditions, and their pluripotent retention capacity in buffaloes can be of prime importance in selective genetic modifications of this species. In the present study, we identified
The goal of the present study was to identify cytochemical markers characteristic of muscle afferents in hatchling chicks. To this end, we stained neurons in the trigeminal mesencephalic nucleus with a variety of markers that label subsets of neurons in avian dorsal root ganglia. We found that
