The Shell of the Invasive Bivalve Species <i>Dreissena polymorpha</i>: Biochemical, Elemental and Textural Investigations - Fig 2
<p>A) Inner and dorsal view of the <i>Dreissena polymorpha</i> shell. B) Infrared spectra of the shell powder.</p
Secondary electron images of the shell microstructure of <i>Dreissena polymorpha</i>.
<p>Black boxes show location of the other views. A) Transversal section. B) Thin uppermost layer constitutes chevron-like columns. C) Crossed-lamellar layer. D) Crossed-lamellar fibres at high magnification. E) Crossed-lamellar layer based on a prismatic aggregate myostracal layer. The lower layer of the view is a complex crossed-lamellar layer. F) Innermost layer of the shell.</p
Capacity of different amounts of <i>D</i>. <i>polymorpha</i> ASM to inhibit the <i>in vitro</i> precipitation of calcium carbonate.
<p>Different quantity of ASM are tested: âąâąâą 10, <b>---</b> 20, <b>-âą-</b> 30 ÎŒg ASM.</p
Quantification of the ASM and AIM organic matrix from <i>Dreissena polymorpha</i> shell.
<p>Quantification of the ASM and AIM organic matrix from <i>Dreissena polymorpha</i> shell.</p
Infrared spectra of the acid soluble and the acid insoluble matrices.
<p>a) ASM and b) AIM.</p
One-dimensional electrophoretic pattern of the ASM (lane 1) and of the LS-AIM (lane 2) on 4â20% SDS-PAGE gel with different staining.
<p>A) Coomassie Blue stained gel (CBB). B) Alcian blue at low pH stained gel. Black points (âą) highlight five discrete bands in the ASM and one in the LS-AIM (around 80 kDa). C) Silver stained gel. D) âStains-allâ stained gel.</p
Location of the sampling site in the SaĂŽne River.
<p>Site is shown by the arrow (â: 47° 08â 82.5âN, 05° 24â 08.5âE; â: 47° 07â 36.4âN, 05° 16â 58.4âE). Target (â) indicates the water quality measuring station of Charrey-sur-SaĂŽne.</p
Enzyme-Linked Lectin Assay (ELLA) with a set of 21 lectins against the ASM organic matrix of the <i>Dreissena polymorpha</i> shell.
<p>The results were normalized to the highest response (Wheat germ agglutinin, WGA) which corresponding to 100%.</p
Two-dimensional electrophoretic patterns of the ASM (A) and of the AIM (B).
<p>Protein samples were loaded on a 7 cm linear pH 3â10 IPG strip and second dimension was performed with a precast 4â20% SDS-PAGE gel. ASM gel was stained with Coomassie Blue and AIM one with silver nitrate.</p
