Binding of extracellular matrix proteins to Aspergillus fumigatus conidia
1996
As detected by confocal immunofluorescence microscopy, binding of fibronectin and laminin appeared to be associated with the protrusions present on the outer cell wall layer of resting Aspergillus fumigatus conidia. Flow cytometry confirmed that binding of laminin to conidia was dose dependent and saturable. Laminin binding was virtually eliminated in trypsin-treated organisms, thus suggesting the protein nature of the binding site. Conidia were also able to specifically adhere to laminin immobilized on microtiter plates. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis and Western blotting (immunoblotting) with laminin and antilaminin antibody of whole conidial homogenates allowed…
Onco-fetal/laminin-binding collagen from colon carcinoma: detection of new sequences.
1995
We have recently identified an oncofetal-laminin binding collagen (OF/LB) composed of three alpha chains, with the apparent molecular mass of about 100 kDa each, but bearing different pI. One of the chains appears markedly acidic in a bidimensional electrophoretic system, where the NEPHGE is used as first dimension separating gel, while the two more basic chains have similar migration as alpha 1(III) and alpha 1(I) collagen chains, respectively. Sequence analyses have been performed on CNBr-peptides, derived from pepsinized triple helical molecules and on tryptic fragments obtained after in gel digestion of the acidic band. The research of sequence homology with computerized databases indic…
