octamer
(gcide) | oligomer \o*lig"o*mer\, n. (Chem.)
A molecule composed of a small number of linked monomer
units; a short polymer; -- compounds called oligomers have
less than one hundred monomer units and usually less than
thirty. Oligomers of increasing length are called dimer,
trimer, tetramer, pentamer, hexamer, heptamer,
octamer, nonamer, decamer, etc. In colloquial
laboratory jargon, they may also be referred to as
nine-mer, ten-mer, eleven-mer, twelve-mer, etc.,
especially for oligomers of greater than eight units.

octamer
(gcide) | octamer \oc"ta*mer\ ([o^]k"t[u^]*m[~e]r), n. [Octa- + Gr. me`ros
part.] (Chem.)
A molecule composed of eight monomer units bound to each
other, usually in a linear array; as, an octamer formed from
eight nucleotides is called an octanucleotide.
[PJC]
Note: An example of an octapeptide might be represented using
the standard abbreviations for the component amino
acids, e.g.: met-ala-ser-glu-lys-ala-val-gly
An octanucleotide might be represented using the
standard single-letter abbreviations for the component
mononucleotides, e.g.: ATGCATGC.
