Free cytoplasmic informosomes isolated from Datura stramonium plants infected by PVX contain a low-molecular ribonucleoprotein complex (RNP). This complex as to its main physico-chemical parameters (sedimentation coefficient 10S, buoyant density in CsSO4 1.31 g/cm3, stability to 1%
Tobacco floral nectar (FN) is a biological fluid produced by nectaries composed of sugars, amino acids and proteins called nectarins, involved in the floral defense. FN provides an ideal source of nutrients for microorganisms. Understanding the role of nectar proteins is essential to predict impacts
Lysosome membrane glycoproteins, lamp-1 and lamp-2, have been shown to contain 18 and 16 N-glycans, some of which are modified by poly-N-acetyl-lactosamine. We have localized the polylactosaminoglycans to specific sites on lamp-1 and lamp-2 purified from human chronic myelogenous leukemia cells.
Expression of apical cell surface proteins and glycoproteins was examined in polarized primary cultures of mouse uterine epithelial cells (UEC). Lectin-gold cytochemistry revealed that wheat germ agglutinin (WGA) bound specifically to the components of the apical glycocalyx as well as intracellular
The molecular integrity of monoclonal antibodies (MCAB) produced by murine hybridoma cell line TB/C3 was studied in batch and continuous-flow cultures. In batch culture, one band of MCAB was detected initially by Western blotting of sodium dodecyl sulfate (SDS)-polyacrylamide gels run under
A glycoprotein antigen with an apparent mw of 45 kD was observed to be predominant in the circulating immune complexes isolated from patients of allergic bronchopulmonary aspergillosis as well as in the immune complexes prepared in vitro. Further characterisation of 45 kD antigen with trypsin showed
