Notes
Numerous strains of different mating types of the marine ciliate Euplotes raikovi have been found to be autonomous excreters into the surrounding medium of specific mating-inducing factors (gamones) (Luporini, P et al., J.exp.zool. 226 (1983) 1 [9]). The gamone from the mating type represented by strain 13 has been isolated and identified as a glycoprotein with a molecular weight (MW) of about 12 kD and a pI of 4. It has been termed euplomone r 13. At a concentration of 3x10(-12) M, euplomone r 13 specifically induces cells of a complementary mating type to unite in conjugation within 2 hr.
