Relative hemagglutination titers of capsid subunits (higher numbers = poor agglutinator)

A relative comparison of protein concentrations that induced agglutination of human erythrocytes.
Higher numbers = poor agglutinator: Like sample (e.g. dodecahedra vs. dodecahedra, fiber heads vs. fiber heads, or trimeric clusters vs. trimeric clusters) can be compare.
The highest concentration of HAd3 dodecahedra alone or in complex with mini-fibers was 3×10−4 µg/µl.
The highest concentration of His-tagged CAV-2 fiber head constructs was 5×10−4 µg/µl. α(2-3,-6,-8 and -9) neuraminidase was used in this assay.
∞ = no agglutination.
