Boiling Reduces Glycan Detection on Glycoproteins
نویسندگان
چکیده
Glycobiology is emerging as a primary field of interest for biological research. As such, it is crucial to develop and improve tools for the study of sugar-modified biomolecules. Many research endeavors in the field of protein glycobiology involve boiling of proteins in sample buffer for 5-10 minutes prior to gel electrophoresis and their further characterization. Here we examined the effect of boiling purified glycoproteins, as well as a mixture of protein lysate, in sample buffer on their sugar content and found that prolonged boiling partially reduces detection of certain glycans, such as of the cytoplasmic OGlcNAc. This should be taken into consideration when characterizing glycans using common assays.

Altered Glycosylation in Tumours Focused to Cancer Diagnosis
The lack of specific and sensitive tumour markers for early detection of cancer is driving a search for new approaches that could identify biomarkers. Markers are needed to alert clinicians at the early stages of tumourogenesis, before the cancer has metastasized, when the therapeutic drugs are more effective. Most tumour markers currently used in clinics are serum glycoproteins, frequently hig...

Early detection of cancer is the key to improving survival. Since most clinically used serum cancer biomarkers are either glycoproteins or glycan structures that can be recognized by specific monoclonal antibodies, developing glycan structure-based biomarkers from human serum/plasma glycoproteins through mass spectrometry (MS) analysis are active research field during the past decades. Numerous...

Aberrant glycosylation on glycoproteins that are either presented on the surface or secreted by cancer cells is a potential source of disease biomarkers and provides insights into disease pathogenesis. N-Glycans of the total serum glycoproteins from advanced breast cancer patients and healthy individuals were sequenced by HPLC with fluorescence detection coupled with exoglycosidase digestions a...

The extensive involvement of glycan-binding proteins (GBPs) as regulators in diverse biological phenomena provides a fundamental reason to investigate their glycan-binding specificities. Here, we developed a glycoconjugate microarray based on an evanescent-field fluorescence-assisted detection principle for investigation of GBPs. Eighty-nine selected multivalent glycoconjugates comprising natur...
متن کاملChanges of major wall polysaccharides and glycoproteins of tobacco cells in response to excess boron
Effects of excess concentrations of boron on major cell wall components of tobacco cells(Nicotiana tabacum L. cv. Burley 21) were studied. Pectin, xyloglucan, hydroxyproline-richglycoproteins (extensin), and arabinogalactan proteins were characterized. Results showedthat increased boron supply resulted in significant decrease in cell and cell wall dry weights.Also, high concentrations of boron ...
