Fig. 5 in Analysis of major sperm proteins in two nematode species from two classes, Enoplus brevis (Enoplea, Enoplida) and Panagrellus redivivus (Chromadorea, Rhabditida), reveals similar localization, but less homology of protein sequences than expected for Nematoda phylum

Fig. 5 Western blot analysis of MSP in E. brevis. a MSP has unusual mobility in gel and is found as protein with weight 36–38 kDa. Both male and female samples reveal MSP signal, because the latter include inseminated females. α-Tubulin was used as a loading control (approximate weight 55 kDa). b Peptide competition assay confirms reactivity of anti-MSP antibodies with protein band of 36–38 kDa
