A blue protein present in the mucus coating blue forms of walleye, Sander vitreus, was purified to homogeneity by a combination of ion exchange and hydrophobic interaction chromatography. The purified protein has a molecular mass of 87,850 and is a homotetramer with a subunit molecular mass of 21,836. Solutions of the protein are deep blue in color and show absorbance maxima at 383 and 633 nm, respectively. Acetone treatment of the protein releases a blue chromophore with the spectral…

The spectral properties and crystal structures of engineered monomeric Sandercyanin-BLA complexes are reported and a mechanism for modulating photo-states in BLA-bound lipocalins, known only in phytochromes till date is postulated.
Localization and seasonal variation of blue pigment (sandercyanin) in walleye (Sander vitreus)
- Environmental Science, Biology
- 2015
Sandercyanin was found solely on dorsal surfaces of the fish and was localized to novel cells in the epidermis, similar in appearance to secretory sacciform cells, and concentrations were significantly higher in fish collected in summer versus other seasons.
Blue protein with red fluorescence
- BiologyProceedings of the National Academy of Sciences
- 2016
It is reported here that the blue pigment of the North American walleye shows bright red fluorescence when excited with UV light, and it is hypothesized that the protection to damaging UV radiation happens by absorption of the UV light and its emission in the lower energy red wavelength.

Contemporary walleye populations possess high levels of genetic diversity and divergence, despite habitat degradation and exploitation, and genetic and previously published tagging data indicate that natal homing and spawning site philopatry led to population structure.

Results reveal broad-scale correspondence to isolation by geographic distance, however, their fine-scale population structures show less relationship, often with pronounced genetic differences among some nearby reproductive groups.
Sexual selection acting on a speciation trait in darters (Percidae: Etheostoma)
- Biology, Psychology

It is demonstrated that female E. barrenense discriminate between the orange and red body hues of conspecific males and exhibit an association preference for orange over red models, providing evidence for a link between sexual selection and behavioral isolation and by extension for a role of sexual selection in speciation.
