bpIs131 [sepa-1p::sepa-1::GFP + unc-76(+)]. Him. SEPA-1::GFP aggregates form in a temporal pattern. Diffuse SEPA-1::GFP is detectible in most cells at the comma stage and greatly diminished by the 2-fold stage. After hatching, cytoplasmic SEPA-1::GFP aggregates were found in a few unidentified cells in the head and tail regions and also in the intestine, especially in the anterior and posterior pairs of intestine cells.
