sambucus nigra/albumin

In our research we used the extract from dietary supplement of elderberry (EE) and its dominant anthocyanin-cyanidin 3-O-glucoside (Cy 3-gluc). By interacting with a model membrane that reflects the main lipid composition of tumor membranes, the extract components, including Cy 3-gluc, caused an

A label-free electrochemical impedance spectroscopy biosensor for selective detection and discrimination of the cancer-associated sialyl-Tn (STn) antigen was developed by using Sambucus nigra agglutinin type I (SNA-I) as the recognition element. The SNA-I biosensor was constructed by immobilizing

A new lectin, purified from black elder-berries, Sambucus nigra L. (SNA I, hereafter called SNA), was used for fractionation of normal human marrow cells. The stem cell enrichment capability of SNA was investigated by comparing colony formation (GM-CFU) in unagglutinated cell fractions (SNA-)

Serum protein glycosylation is known to be affected by pathological conditions, including cancer and inflammatory diseases. Pancreatic cancer patients would benefit from early diagnosis, as the disease is often detected in an advanced stage and has poor prognosis. Searching for changes in serum

Carbohydrates have been suggested to account for some IgE cross-reactions between various plant, insect, and mollusk extracts, while some IgG antibodies have been successfully raised against plant glycoproteins. A rat monoclonal antibody raised against elderberry abscission tissue (YZ1/2.23) and

Growing evidence supports a cardio-protective role for anthocyanins; however, there is limited evidence on their efficacy and safety following the consumption of relatively high but dietarily achievable doses in humans. We conducted a parallel-designed, randomized, placebo-controlled study to

Lectins are carbohydrate binding proteins found in plants, animals, and microorganisms. They serve as important models for understanding protein-carbohydrate interactions at the molecular level. We report here the fabrication of a novel sensing interface of biotinylated sialosides to probe

A solid-phase assay for the activity of CMPNeuAc:Gal beta 1-4GlcNAc-R alpha-2,6-sialyltransferase (2,6ST) has been developed. In the assay an acceptor glycoprotein is immobilized onto microtiter plate wells. The two glycoprotein acceptors used were asialofetuin (ASF), which contains oligosaccharides

This work describes the bioadhesive properties of poly(methyl vinyl ether-co-maleic anhydride) (PVM/MA) nanoparticles fluorescently-labelled with rhodamine B isothiocyanate, and coated with either Sambucus nigra lectin (SNA-NP) or bovine serum albumin (BSA-NP). The different formulations (10 mg)

In this study, we characterized the glycome of cervical-vaginal fluid, collected with a Catamenial cup. We quantified: glycosidase levels; sialic acid and high mannose specific lectin binding; mucins, MUC1, MUC4, MUC5AC, MUC7; and albumin in the samples collected. These data were analyzed in the

The identification of biocompatible nanomaterials with high conductivities as sensing interfaces is important in developing novel electrochemical cytosensors. We prepared a novel protein-inorganic nanomaterial-bovine serum albumin (BSA) incorporated Ag nanoflowers with three-dimensional porous
