The four minor pseudopilin soluble constructs XcpHp, XcpIp, XcpJp, and XcpKp contain 25, 14, 36, and 42 acidic residues, respectively, distributed along their primary sequences. Thus the use of adipic acid dihydrazide (ADH) coupled to 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methyl-...
(clone D21H11; Cell Signaling Technology) at 1:1000 ratio. For the secondary antibody visualization, Goat anti-Rabbit or Goat anti-Mouse Alexa-Fluor 800 nm (Thermo Fisher Scientific) was used to bind the primary antibodies. An equal amount of pooled urine EVs was loaded in lane 1 of ...
while the production rate of the related oxidation products in UOOA are enhanced during summer resulting in its dominant contribution. In contrast, the primary (BBOA and CPOA) and secondary (COOA) fractions related to biofuel combustion are mainly observed during the cold period due to residential...
