The alga was chosen not because of its colour or the two flagella it uses to swim but because, of all the primary producers in the aquatic environment at the the lowest level of the food chain of the food chain, it is the one whose genome has been fully sequenced.
The fusion protein also contains flagellin (FliC), a peptide found in nearly all bacteria with flagella (lash-like appendages) that acts as a strong catalyst when administered together with other antigens or foreign substances that induce an immune response in the body.
Using field emission scanning electron microscopy (FESEM), we first investigated the morphology (typology and topology) of cuticular sensilla on both the medial and lateral flagella of the antennules, with special attention paid to the aesthetasc sensilla.

Objective: The centriole is the largest evolutionary conserved macromolecular structure responsible for building centrosomes and cilia or flagella in many eukaryotes.
blattarum is usually round, oval, or pyriform, with size range from approximately 15 to 40 [micro]m, with a tuft of flagella extending from the anterior end of the organism.
In this workflow, bacterial isolates are cultured overnight, resuspended in water, and then flagella are captured and tryptically digested on a syringe filter.
